New study: there is no gay gene that causes homosexuality

I heard one of the authors of this new study commenting on how he was a gay man, and the purpose of his research was to show a genetic basis for homosexuality, in order to make it equal to race. His goal was to make it impossible to disagree with homosexual behavior, because homosexual behavior would be seen as natural and normal. Let’s see if his new study helps him out.

The blog of the peer-reviewed journal PLOS One reported on the new study, which was published in the prestigious journal Science.

Excerpt:

The once-prevailing concept of a “gay gene” dictating sexual orientation has been put to rest in a powerhouse study published today in Science. The work brilliantly illustrates the very nature of science: evolving with the input of new data, especially the large-scale contributions of bioinformatics and crowd-sourcing.

“We formed a large international consortium and collected data for more than 500,000 people, comparing DNA and self-reported sexual behavior. This is approximately 100 times bigger than any previous study on this topic,” said lead author Andrea Ganna, of the Institute of Molecular Medicine in Finland and an instructor at Massachusetts General Hospital and Harvard Medical School, opening a news conference earlier this week.

[…]The investigation estimates a genetic contribution to same-sex sexual behavior as under 1 percent, thanks to analysis of a trove of data from the UK Biobank and the consumer genetic testing company 23andme.

So, there you have it, there is no gay gene. But this is of course something we’ve known for decades, as all the previous studies had found the same thing.

The normal way that people do these studies is to analyze identical twins, and see how often both identical twins are gay.

Eight major studies of identical twins in Australia, the U.S., and Scandinavia during the last two decades all arrive at the same conclusion: gays were not born that way.

“At best genetics is a minor factor,” says Dr. Neil Whitehead, PhD. Whitehead worked for the New Zealand government as a scientific researcher for 24 years, then spent four years working for the United Nations and International Atomic Energy Agency. Most recently, he serves as a consultant to Japanese universities about the effects of radiation exposure. His PhD is in biochemistry and statistics.

Identical twins have the same genes or DNA. They are nurtured in equal prenatal conditions. If homosexuality is caused by genetics or prenatal conditions and one twin is gay, the co-twin should also be gay.

“Because they have identical DNA, it ought to be 100%,” Dr. Whitehead notes. But the studies reveal something else. “If an identical twin has same-sex attraction the chances the co-twin has it are only about 11% for men and 14% for women.”

Because identical twins are always genetically identical, homosexuality cannot be genetically dictated. “No-one is born gay,” he notes. “The predominant things that create homosexuality in one identical twin and not in the other have to be post-birth factors.”

Dr. Whitehead believes same-sex attraction (SSA) is caused by “non-shared factors,” things happening to one twin but not the other, or a personal response to an event by one of the twins and not the other.

By the way, a previous study also found that transgender behavior was not genetic, but was clearly linked to environmental factors such as peer approval and social media.

Here is the report from Science Daily:

This month, a Brown University researcher published the first study to empirically describe teens and young adults who did not have symptoms of gender dysphoria during childhood but who were observed by their parents to rapidly develop gender dysphoria symptoms over days, weeks or months during or after puberty.

[…]The study was published on Aug. 16 in PLOS ONE.

Littman surveyed more than 250 parents of children who suddenly developed gender dysphoria symptoms during or after puberty.

[…]“Of the parents who provided information about their child’s friendship group, about a third responded that more than half of the kids in the friendship group became transgender-identified,” Littman said. “A group with 50 percent of its members becoming transgender-identified represents a rate that is more 70 times the expected prevalence for young adults.”

A previous study also found that children are more likely to be gay if they are raised by gay adults. It was reported in AOL News.

Excerpt:

Walter Schumm knows what he’s about to do is unpopular: publish a study arguing that gay parents are more likely to raise gay children than straight parents. But the Kansas State University family studies professor has a detailed analysis that past almost aggressively ideological researchers never had.

[…]His study on sexual orientation, out next month, says that gay and lesbian parents are far more likely to have children who become gay. “I’m trying to prove that it’s not 100 percent genetic,” Schumm tells AOL News.

His study is a meta-analysis of existing work. First, Schumm extrapolated data from 10 books on gay parenting… [and] skewed his data so that only self-identified gay and lesbian children would be labeled as such.

[…]Schumm concluded that children of lesbian parents identified themselves as gay 31 percent of the time; children of gay men had gay children 19 percent of the time, and children of a lesbian mother and gay father had at least one gay child 25 percent of the time.

[…]Finally, Schumm looked at the existing academic studies… In all there are 26 such studies. Schumm ran the numbers from them and concluded that, surprisingly, 20 percent of the kids of gay parents were gay themselves. When children only 17 or older were included in the analysis, 28 percent were gay.

It’s very important for people to understand that there is a trend in society to make every behavior traditionally seen as sinful into something caused by genetics. The twin goals of this effort are to insulate the behaviors from criticism, and to minimize evaluation of the effects of these behaviors on society as a whole. The genetic argument was used extensively to normalize same-sex marriage and transgenderism. I have seen the genetic argument used to defend other behaviors like pedophilia and incest. But the scientific research does nothing to support any of these arguments. What’s amazing is how a majority of people in the United States have such false beliefs about the scientific research. They vastly overestimate the number of gay people, and also the influence of genetics.

Does the fossil record match Darwinist predictions or Design predictions?

Recently, I wrote a post about how you can make a simple argument for intelligent design based on junk DNA.  Step 1: find out what Darwinian naturalists claim about junk DNA. Step 2: find out what design proponents claim about junk DNA. Step 3: compare those predictions with scientific discoveries about junk DNA over the past decades. Today we’ll do it with the fossil record.

I’m going to use an amazing article from Günter Bechly from over at Evolution News. Günter writes an article about fossils every Friday (he calls it “Fossil Friday”).

Here’s last Friday’s article, where he gave a nice overview of why Christians should care about the fossil record.

He writes:

This Fossil Friday I want to address the common request to provide an expanded written form of my lectures on discontinuities in the fossil record (e.g., on YouTube) together with references to mainstream scientific papers that back up these arguments against neo-Darwinism. Since the sudden appearance of trilobites in the Cambrian Explosion is one of the best known examples for discontinuities in the fossil record, I chose the early trilobite Wanneria sp. from the Lower Cambrian of Canada as today’s featured fossil. So let’s jump right in.

Then he talks about the predictions of Darwinists and design proponents:

Every theory makes certain predictions and these predictions have to be tested with empirical evidence. Charles Darwin’s theory of evolution necessarily predicts a gradual development of life. Therefore he insisted on gradualism, against the advice of his good friend Thomas Huxley. Darwin quoted in his magnum opus The Origin of Species (Darwin 1859) not less that six times the Latin dictum “natura non facit saltus”, nature does not make jumps, because he wanted to present a fully naturalistic explanation for the history of life on our planet, knowing perfectly well that saltations would have tacitly implied miracle-like intelligent interventions. The prediction of gradualism is not accidental and not a dispensable side issue in Darwinism. This was made clear by Richard Dawkins, arguably the most ardent modern popularizer of Darwinism, in his bestselling book The Greatest Show on Earth (Dawkins 2009), where he explicitly clarified that “Evolution not only is a gradual process as a matter of fact; it has to be gradual if it is to do any explanatory work.” In another book titled Climbing Mount Improbable (Dawkins 1996) he explained the reasons with a beautiful metaphor: Imagine the task to reach the top of a steep and tall cliff from the sea shore. It would be an improbable (or rather impossible) miracle to achieve this task with a single big jump. However, if there was a gentle slope on the backside of the cliff, you could easily and effortlessly climb the mountain with a lot of small successive steps. This is the way evolution must operate according to Darwin and Dawkins: not by sudden miraculous jumps, but many small steps, that are each not unlikely to happen accidentally without intelligent intervention, and which accumulate over long periods of time to add up to big biological differences.

Engineers don’t check in code gradually, one letter at a time. We check in a bunch of related changes to different files that implement some feature. Some days, I have a lot of meetings. Some days, I spend time doing code reviews or making diagrams or writing documentation. And some days, I get to write code all day. So, if you look at my Github history, you’ll see that some days I have 35 commits, and other days none. That’s consistent with having a “designer”. The complexity increases in “jumps”, with each jump containing changes to several files, and the changes add some new feature. But that’s not available to Dawkins and Darwin, they don’t like engineers, or sudden jumps in complexity.

Günter lists out a bunch of biological “jumps”, where God pulled an all-nighter, with pizza and Mountain Dew, and checked in a whole bunch of new code all at once.

Here are a few from his list of about 15 of them:

  • The Origin of Life (3.8 bya)
  • The Origin of Photosynthesis (3.8 bya)
  • The Cambrian Explosion (537-508 mya)
  • The Carboniferous Insect Explosion (325-314/307 mya)
  • The Early Triassic Marine Reptile Radiation (248-240 mya)
  • The Mid Triassic Gliding / Flying Reptile Radiation (230-210 mya)
  • Upper Triassic Dinosaur Explosion (234-232 mya)
  • The Abominable Mystery of the Origin of Flowering Plants (130-115 mya)
  • The Paleogene Big Bang of Modern Birds (65-55 mya)

Günter has the details of each of these, but if you have listened to our recent episode about the origin of life with Dr. Fazala Rana, then you already know about the first one. The point is that the fossil record has a whole bunch of “big bangs”, where God checked in a whole bunch of new code in a very short period of time. This is strictly forbidden in Darwinian theory, but the fossil record doesn’t care about theories.

Günter concludes:

The gradualistic core predictions of any unguided evolutionary mechanisms such as neo-Darwinism are strongly contradicted by the empirical evidence. The cumulative conflicting evidence from molecular biology, genetics, population genetics, and the discontinuous fossil record can no longer be explained away as anomalies or as artifacts such as under-sampling of an incomplete fossil record. The total evidence is better explained with pulses of infusion of new information from outside of the system (top-down), rather than with a purely mechanistic stepwise bottom-up process. The only known cause in the universe that is able to produce significant amounts of new complex specified information is the activity of an intelligent conscious agent, so that intelligent design theory qualifies as superior alternative to unguided Darwinian evolution in an inference to the best explanation (abductive reasoning) among competing hypotheses. This is not an argument from ignorance (i.e., God of the gaps) as is often incorrectly claimed by critics, but is based on empirical data and our positive knowledge about the regular causal structure of the universe and the type of causes that exclusively are known to produce certain effects.

And I found a nice lecture that he gave on the topic:

The article was tough for me to understand, but I think I got the big picture of what he was saying. I blogged on it so that I can find it again if I get questions about what evidence there is for a designer. I sure hope that we are making more scientists like him for Team Design, because his post was quality work.

Science and Faith conference scheduled for February 8th, 2025 in Dallas, TX

I noticed that there is a new Dallas, TX Science and Faith conference scheduled for February 8th, 2025. This one is offering online viewing, if you can’t make it to Dallas. Well, I thought it might be fun to review some lectures from the 2019 Dallas, TX Science and Faith conference, because they posted them online. It’s a nice way to get an easy, popular-level introduction to science apologetics.

Here are a few of the sessions from the upcoming conference that I’m looking forward to:

  • The miracle of butterfly metamorphosis (Paul Nelson)
  • The amazing honeybee (Eric Hedin)
  • The scientific evidence of the human soul (Michael Egnor)
  • The intelligent design of plants (Emily & Daniel Reeves)
  • The theory of ID as fuel for scientific discovery (Casey Luskin)
  • The origin of animal body plans (Stephen Meyer)

When it comes to scientific arguments, I have 6 that I usually use:

  • origin of the universe
  • fine-tuning of the initial conditions of the universe
  • origin of the life
  • sudden origin of body plans in the Cambrian explosion
  • habitability and discoverability
  • molecular machines

If you want to get an idea of what these events are about, the ID folks did one of these conferences about 6 years ago in 2019, and they posted the videos. And they actually covered a few of these arguments.

Here is the YouTube playlist. And below are some of the lectures.

The origin of the universe:

The origin of life:

Habitability and Discoverability:

Cambrian explosion:

If you’re wondering, “is this the lecture where James Tour got really, really excited with a church audience?” Yes, this is the one.

One of my heroes is speaking at the 2025 conference, Dr. Richard Sternberg. You might remember that Dr. Sternberg was thrown out of his job at the Smithsonian Institute, just for publishing a paper by Dr. Stephen Meyer that supported intelligent design in a peer-reviewed journal.

For decades, opponents of intelligent design derided the theory as unscientific because it hadn’t been published in peer-reviewed science journals. “What intelligent design advocates fail to realize is that the peer-review process could benefit them enormously,” sneered one such opponent, computer scientist Jeffrey Shallit, in 2001. But when a peer-reviewed journal published an ID-friendly paper in 2004, the response from Darwinists was simply more derision. And for Dr. Richard Sternberg, it was worse. Sternberg endured sustained hostility from his colleagues at the Smithsonian, including conspiracy theories and wild accusations, that damaged his reputation and resulted in his premature departure.

These are the real heroes. The ones who have to pay a price for standing up for the truth.

Here is his biography:

Richard Sternberg is an evolutionary biologist with interests in the relation between genes and morphological homologies, and the nature of genomic “information.” He holds two Ph.D.’s: one in Biology (Molecular Evolution) from Florida International University and another in Systems Science (Theoretical Biology) from Binghamton University. From 2001-2007, he served as a staff scientist at the National Center for Biotechnology Information, and from 2001-2007 was a Research Associate at the Smithsonian’s National Museum of Natural History. Dr. Sternberg is presently a research scientist at the Biologic Institute, supported by a research fellowship from the Center for Science and Culture at Discovery Institute. He is also a Research Collaborator at the National Museum of Natural History.

From 2001-2004, Sternberg served as Managing Editor of the Proceedings of the Biological Society of Washington, and has also served on the Editorial Board of the International Journal of General Systems. In 1999, he was a Visiting Associate Professor of Biology at Northern Michigan University, and from 1999-2001 was a Postdoctoral Fellow in the Department of Invertebrate Zoology, National Museum of Natural History. He has received postdoctoral fellowships from both the NIH and the National Museum of Natural History, and has published refereed articles in such journals as Genetica, Evolutionary Theory, Journal of Comparative Biology, Crustacean Research, Journal of Natural History, Journal of Morphology, Journal of Biological Systems, and the Annals of the New York Academy of Sciences.

People sometimes try to talk to me about charismatic pastors, and Big Eva politicians, famous Christian athletes, famous Christian artists, etc. And I just have no regard for people who talk about things that they haven’t investigated themselves. I’m even a little suspicious of analytic philosophers! The guys who I admire and look up to are the STEM guys. The mathematicians and the scientists. The guys who work in the labs. The guys who move the ball forwards by giving us evidence that we can talk about and use with people who don’t even know where to begin looking for evidence.
