New study: first life pushed back earlier, leaving less time for naturalist magic

Christianity and the progress of science

Whenever you discuss origins with naturalists, it’s very important to get them to explain how the first living organism emerged without any help from an intelligent agent. The origin of life is an information problem. A certain minimal amount of biological information for minimum life function has to be thrown together by chance. No evolutionary mechanisms have the potential to work until replication is already in place.

Evolution News reports on a new study that makes the window for naturalistic forces to create the first self-replicating organism even smaller.

Excerpt:

A paper in Nature reports the discovery of fossil microbes possibly older, even much older, than any found previously. The lead author is biogeochemist Matthew Dodd, a PhD student at University College London. If the paper is right, these Canadian fossils could be 3.77 billion years old, or even as old as — hold onto your hat, in case you’re wearing one — 4.28 billion years.

From the Abstract:

Although it is not known when or where life on Earth began, some of the earliest habitable environments may have been submarine-hydrothermal vents. Here we describe putative fossilized microorganisms that are at least 3,770 million and possibly 4,280 million years old in ferruginous sedimentary rocks, interpreted as seafloor-hydrothermal vent-related precipitates, from the Nuvvuagittuq belt in Quebec, Canada. These structures occur as micrometre-scale haematite tubes and filaments with morphologies and mineral assemblages similar to those of filamentous microorganisms from modern hydrothermal vent precipitates and analogous microfossils in younger rocks. The Nuvvuagittuq rocks contain isotopically light carbon in carbonate and carbonaceous material, which occurs as graphitic inclusions in diagenetic carbonate rosettes, apatite blades intergrown among carbonate rosettes and magnetite–haematite granules, and is associated with carbonate in direct contact with the putative microfossils.

This new paper is interesting to compare with a paper from last year, Nutman et al., “Rapid emergence of life shown by discovery of 3,700-million-year-old microbial structures,” also in Nature, which found microbial structures that are a bit younger.

But the “microbial structures” from Nutman et al. 2016 are different from these new “microfossils” presented by Dodd et al. 2017. In Nutman et al., they only found stromatolite-type structures rather than actual microfossils. Some stromatolite experts were a bit skeptical that what they found were really stromatolites.

But the new paper by Dodd and his colleagues, “Evidence for early life in Earth’s oldest hydrothermal vent precipitates,” seems to offer potential bacteria-like microfossils. They are tiny black carbonaceous spheres and “hematite tubes” which the authors think are biogenically created. We’ve seen more convincing ancient microfossils, but these aren’t bad.

According to Dodd et al., these new finds would be the oldest known microfossils, if that is in fact what they are. Very interesting. If so, that just keeps pushing unquestionable evidence of life’s existence on Earth further and further back, which leaves less and less time for the origin of life to have occurred by unguided chemical evolution after Earth became habitable.

If they are in fact 4.28 billion years old, then that would mean there was life very, very early in Earth’s history — as Cyril Ponnamperuma said, it’s like “instant life.”

Instant life is “rational” for naturalistic fideists, but for evidence-driven people who understand the long odds on generating even a simple protein by chance, it’s irrationality.

Let’s recall exactly how hard it is to make even a simple protein without intelligent agency to select the elements of the sequence.

The odds of creating even a single functional protein

I’ve talked about Doug Axe before when I described how to calculate the odds of getting functional proteins by chance.

Let’s calculate the odds of building a protein composed of a functional chain of 100 amino acids, by chance. (Think of a meaningful English sentence built with 100 scrabble letters, held together with glue)

Sub-problems:

  • BONDING: You need 99 peptide bonds between the 100 amino acids. The odds of getting a peptide bond is 50%. The probability of building a chain of one hundred amino acids in which all linkages involve peptide bonds is roughly (1/2)^99 or 1 chance in 10^30.
  • CHIRALITY: You need 100 left-handed amino acids. The odds of getting a left-handed amino acid is 50%. The probability of attaining at random only L–amino acids in a hypothetical peptide chain one hundred amino acids long is (1/2)^100 or again roughly 1 chance in 10^30.
  • SEQUENCE: You need to choose the correct amino acid for each of the 100 links. The odds of getting the right one are 1 in 20. Even if you allow for some variation, the odds of getting a functional sequence is (1/20)^100 or 1 in 10^65.

The final probability of getting a functional protein composed of 100 amino acids is 1 in 10^125. Even if you fill the universe with pre-biotic soup, and react amino acids at Planck time (very fast!) for 14 billion years, you are probably not going to get even 1 such protein. And you need at least 100 of them for minimal life functions, plus DNA and RNA.

Research performed by Doug Axe at Cambridge University, and published in the peer-reviewed Journal of Molecular Biology, has shown that the number of functional amino acid sequences is tiny:

Doug Axe’s research likewise studies genes that it turns out show great evidence of design. Axe studied the sensitivities of protein function to mutations. In these “mutational sensitivity” tests, Dr. Axe mutated certain amino acids in various proteins, or studied the differences between similar proteins, to see how mutations or changes affected their ability to function properly. He found that protein function was highly sensitive to mutation, and that proteins are not very tolerant to changes in their amino acid sequences. In other words, when you mutate, tweak, or change these proteins slightly, they stopped working. In one of his papers, he thus concludes that “functional folds require highly extraordinary sequences,” and that functional protein folds “may be as low as 1 in 10^77.”

The problem of forming DNA by sequencing nucleotides faces similar difficulties. And remember, mutation and selection cannot explain the origin of the first sequence, because mutation and selection require replication, which does not exist until that first living cell is already in place.

Is Christianity intended to provide you with health, wealth and happiness?

Is Christianity supposed to provide you with health and wealth?

Consider post on the Gospel Coalition.

It says:

I am a pastor in a small village about 500 kilometers west of Nairobi—in Kenya’s sugar belt region. For the better part of my adult life, I was a Pentecostal/charismatic/Word of Faith preacher. But the day came when my faith made no sense at all.

I first heard the gospel as a young man, though the message contained false advertising about a Jesus who would meet all my needs and fulfill all my dreams. Remaining unsaved would lead to a life of misery, sickness, and poverty, I was told. It appeared logical, then, to embrace Christ and step into a world of limitless blessing.

I wanted all God had for me, and I zealously rose to become a herald of the message I had received—which I later learned is Word of Faith teaching some call the “prosperity gospel.” I knew of no other gospel. I believed God was good, and this meant nothing uncomfortable came from him.

I learned to deal with Satan for causing anything negative in my life. Spiritual warfare was ingrained in me. As part of the “God class,” as Word of Faith teachers say, I had absolute authority to create my own world through positive thinking and faith-based confessions.

I believed God’s will included health and wealth, which I could call into existence by faith. Anything less should be repudiated. If all else failed, I could engage the heavenly language of angels—praying in tongues—to bypass Satan and the hosts of darkness.

Do you believe any of that?

Well, the pastor goes on to explain all the terrible things that happened to him – and these are the most difficult experiences that can happen to anyone. How did he respond to God allowing all these bad things happening to him?

Well, pretty badly at first:

Without answers, we were dismayed with God, whose ways no longer made sense to us. Though faith became a mirage, we kept up appearances, trying to pretend we didn’t despair. Yet inwardly we felt doubtful, hopeless, even cursed.

How could we reconcile these bad things with a good God? Our Word of Faith teaching instructed us to dismiss Job’s suffering as a consequence of his negative confession: “The LORD gave, and the LORD has taken away” (Job 1:21). But how could we make sense of Paul himself falling sick (Gal. 4:13) and yet rejoicing in his afflictions (2 Cor. 12:10)? How could we continue to reconcile this portrait with modern “super-apostles” who market health and wealth in their books, DVDs, and mega-meetings?

In my faith crisis and anger at God, I vowed to quit the ministry. I felt like a fraud for preaching a “gospel” that did not work. God had become an enigma, and faith a labyrinth. Yet the passage of time and the routine activities of Churchianity soothed our restless minds—for a while.

But then this happened:

My friend asked me to translate in Swahili as Billy delivered a message in English. The topic, “justification by faith alone through the imputed righteousness of Christ,” sounded ridiculous to me. Onstage for one awkward hour, I forced myself to deliver words I believed were unbiblical and heretical. But the sovereign Lord worked in my heart, calling forth reason through an inner witness to the truths proclaimed. The Holy Spirit planted sufficient doubt about the system I’d defended.

Over the next three weeks I felt tortured by God for my errors, which became apparent with every Bible text I once thought supported my beliefs. The same verses now looked different, affirming Billy’s message.

[…]Though I didn’t understand the fine points of theology, my conversion was decisive. Enthralled by Christ, who bids his own to “take up his cross daily and follow me” (Luke 9:23), I now felt that “the sufferings of the present time are not worth comparing with the glory that is to be revealed to us” (Rom. 8:18).

I guess I should say the obvious – I have no idea how you would get the idea that you can coerce God into giving you health, wealth and prosperity. This is such an immature view of God. Anyone who has ever been involved in any kind of serious enterprise knows that the best people are the ones who stick to the mission through thick and thin, and just keep on fighting through the hunger, suffering, sickness and other setbacks. And that’s everywhere in the Bible. For goodness sake: Jesus was obedient to God to the point of suffering torture and giving his life as a sacrifice to save others from their rebellion against God. How do you get health, wealth and happiness from that?

But more than that, this makes me think of when I was young and first exposed to the Christian message. Far from being something that pushed me away from Christianity, the Bible’s message of suffering with honor, and doing the moral thing regardless of happy outcomes, really resonated with me. It is very real world. In this world, it is rare that doing the right thing works out for you. In fact, there should be some area of your life where you are missing something that you really want and need. Consider that a joy, because when you are poor and hungry sad and meek, that’s when you are most like the people in the Bible who had to experience these things while remaining faithful and obedient. For me, not being married and not being a father is my empty hole that will never be filled. I get asked about it a lot by my co-workers, and they know I am not happy about it, but they also know I am still faithful even if my needs are not met.

These are my two favorite passages in the Bible:

1 Corinthians 4:2:

1 This is how one should regard us, as servants of Christ and stewards of the mysteries of God.

2 Moreover, it is required of stewards that they be found faithful.

3 But with me it is a very small thing that I should be judged by you or by any human court. In fact, I do not even judge myself.

4 For I am not aware of anything against myself, but I am not thereby acquitted. It is the Lord who judges me.

Matthew 5:13:

10 “Blessed are those who have been persecuted for the sake of righteousness, for theirs is the kingdom of heaven.

11 “Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me.

12 Rejoice and be glad, for your reward in heaven is great; for in the same way they persecuted the prophets who were before you.

13 “You are the salt of the earth; but if the salt has become tasteless, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled under foot by men.

14 “You are the light of the world. A city set on a hill cannot be hidden;

15 nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house.

The Bible doesn’t shy away from suffering and evil. That’s part of the normal Christian life. And how you respond to lack and suffering and evil is a powerful signal to the watching world about what Christianity is all about.

From a practical point of view, I do recommend making good decisions to prepare for potential troubles and tragedies. If you are careful to make yourself defensible to unexpected setbacks, not only will you be able to endure them, but you will be strong to help others endure them, too. The goal is to not let go of God because unmet desires and dashed expectations. A wise person understands that everyone has a breaking point, but with a little wisdom and preparation, you can build your defenses so that the stress that might break someone less prepared does not break you.

Study: brain of child neglected by mother is smaller and underdeveloped

Dina sent me this article from the UK Daily Mail. In the past, I’ve written about how much children need their fathers, but this time I’m focusing on how much children need their mothers, especially in the first 5 years of development.

Here is two brain scans to compare:

Brain scans of 3-year old children: normal vs neglected
Brain scans of 3-year old children: normal vs neglected

Excerpt:

Both of these images are brain scans of a two three-year-old children, but the brain on the left is considerably larger, has fewer spots and less dark areas, compared to the one on the right.

According to neurologists this sizeable difference has one primary cause – the way each child was treated by their mothers.

The child with the larger and more fully developed brain was looked after by its mother – she was constantly responsive to her baby, reported The Sunday Telegraph.

But the child with the shrunken brain was the victim of severe neglect and abuse.

According to research reported by the newspaper, the brain on the right worryingly lacks some of the most fundamental areas present in the image on the left.

The consequences of these deficits are pronounced – the child on the left with the larger brain will be more intelligent and more likely to develop the social ability to empathise with others.

But in contrast, the child with the shrunken brain will be more likely to become addicted to drugs and involved in violent crimes, much more likely to be unemployed and to be dependent on state benefits.

The child is also more likely to develop mental and other serious health problems.

Professor Allan Schore, of UCLA, told The Sunday Telegraph that if a baby is not treated properly in the first two years of life, it can have a fundamental impact on development.

He pointed out that the genes for several aspects of brain function, including intelligence, cannot function.

[…]The study correlates with research released earlier this year that found that children who are given love and affection from their mothers early in life are smarter with a better ability to learn.

The study by child psychiatrists and neuroscientists at Washington University School of Medicine in St. Louis, found school-aged children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress.

The research was the first to show that changes in this critical region of children’s brain anatomy are linked to a mother’s nurturing, Neurosciencenews.com reports.

The research is published online in the Proceedings of the National Academy of Sciences Early Edition.

Lead author Joan L. Luby, MD, professor of child psychiatry, said the study reinforces how important nurturing parents are to a child’s development.

My friend Katy tweeted this article from far-left NPR:

Parents do a lot more than make sure a child has food and shelter, researchers say. They play a critical role in brain development.

More than a decade of research on children raised in institutions shows that “neglect is awful for the brain,” says Charles Nelson, a professor of pediatrics at Harvard Medical School and Boston Children’s Hospital. Without someone who is a reliable source of attention, affection and stimulation, he says, “the wiring of the brain goes awry.” The result can be long-term mental and emotional problems.

The article goes on to talk about children who grow up without mothers in Romanian orphanages:

As the children grew older, the researchers were able to use MRI to study the anatomy of their brains. And once again, the results were troubling. “We found a dramatic reduction in what’s referred to as gray matter and in white matter,” Nelson says. “In other words, their brains were actually physically smaller.”

The scientists realized the cause wasn’t anything as simple as malnutrition. It was a different kind of deprivation — the lack of a parent, or someone who acted like a parent.

A baby “comes into the world expecting someone to take care of them and invest in them,” Nelson says. “And then they form this bond or this relationship with this caregiver.” But for many Romanian orphans, there wasn’t even a person to take them out of the crib.

“Now what happens is that you’re staring at a white ceiling, or no one is talking to you, or no one is soothing you when you get upset,” Nelson says. So areas of the brain involved in vision and language and emotion don’t get wired correctly.

I expect the woman I marry (if I marry) to have a college degree, and preferably a graduate degree, and a couple of years of employment. But I think to be fair to the research on child development, she has to stay home and invest in those children through the first five years at least. After that she can stay home or work as much as she thinks is beneficial to the family goals of impacting the university, the church and the public square – as well as continuing to raise those children.  I would take over more of the parenting as the children’s needs changed. When it comes to children, we work backward from their needs, and those needs create responsibilities and obligations on the grown-ups. That doesn’t mean the children are spoiled – it means that they get what they need.

Christian parents have to go even further

Here is a relevant post from Lindsay, a Christian mother who has a graduate degree in biology and was teaching biology before leaving her career to care for her children.

She writes:

Now, can a woman handle the logistics of the home, ensure her family is cared for, and still work outside the home? Perhaps, in some cases – especially if they do not yet have children. But no woman is Superwoman. We all have limitations. It’s just not possible for any woman to adequately care for children and home while holding down a full time job. The care of children and the home is primarily a woman’s responsibility in a way it isn’t for her husband. If there are no children, it may be possible for her to care for the home and her husband and still keep a job outside the home, but she must keep the home and her husband as her priority.

Once children arrive, it becomes pretty much impossible for her to work outside the home and still fulfill her duties at home. The funny thing about children is that they need constant care. One cannot care for children and work outside the home too. The choice once children come along is whether to outsource the care of the children to someone else or to do it yourself. I firmly believe that God entrusts children to a husband and wife because he wants them to be the primary influences in their children’s lives. That doesn’t happen if the children spend a majority of their waking hours in the care of someone else.

Children don’t just need food and shelter provided to them, they need love, teaching, discipline, a sense of security, and examples of how they are to live. All of those things are best done when the child spends time primarily with his or her parents. Daycare workers, school teachers, and even grandparents simply cannot provide them in the same way parents can. No one loves a child like his own parents do. No one has such a vested interest in ensuring that he grows up with the proper spiritual and moral training. Even if others care about the child, the responsibility for the training of a child belongs to his parents. Daycare workers and teachers and grandparents won’t answer to God for the soul of that child. His parents will.

For Christian parents, the stakes are even higher. Not only do they have to care about basic needs of child, but the higher spiritual needs as well. Men really need to be careful to pick a mother for their child who has demonstrated ability in caring for the needs of others, letting the needs of others override her own selfish desires.
