Did your science textbook teach that embryo drawings prove evolution?

Haeckel's embryos and scientific fraud
Haeckel’s embryos and scientific fraud

Jonathan Wells, a biologist with Ph.Ds from Yale and UC Berkeley, writes about one example of fake evidence here:

Charles Darwin thought that “by far the strongest” evidence that humans and fish are descended from a common ancestor was the striking similarity of their early embryos. According to Darwin, the fact that “the embryos of the most distinct species belonging to the same class are closely similar, but become, when fully developed, widely dissimilar… reveals community of descent.” 2 To illustrate this, German Darwinist Ernst Haeckel made some drawings in the 1860s to show that the embryos of vertebrates (fish, amphibians, reptiles, birds and mammals) look almost identical in their earliest stages.

But Haeckel faked his drawings. Not only do they distort vertebrate embryos by making them appear more similar than they really are (in a way that Stephen Jay Gould wrote “can only be called fraudulent” 3), but they also omit classes and stages that do not fit Darwin’s theory. Most significantly, Haeckel omitted the earliest stages, in which vertebrate embryos are strikingly different from each other. The stage he portrayed as the first is actually midway through development. Yet according to Darwin’s logic, early dis-similarities do not provide evidence for common ancestry.

Haeckel used his faked drawings to support not only Darwinian evolution, but also his own “Biogenetic Law,” which stated that embryos pass through the adult stages of their ancestors in the process of development.

…Haeckel’s drawings were exposed as fakes by his own contemporaries, and his Biogenetic Law was thoroughly discredited by 20th century biologists. It is now generally acknowledged that early embryos never resemble the adults of their supposed ancestors. A modern version of recapitulation claims that early embryos resemble the embryos of their ancestors, but since fossil embryos are extremely rare, this claim is little more than speculation based on the assumption that Darwin’s theory is true.

Now the standard response from Darwinists: no textbooks are still using the fraudulent embryo images.

You can see the actual faked pictures from the modern textbooks here. These textbooks were being produced as late as 2004, even though the fraud was detected in the 1800s! Is this the vaunted self-correction of science, or science being twisted to support social and political goals?

And this excerpt from that article is interesting:

Some Darwinists continue to deny that there has been any misuse of Haeckel in recent times. If that is the case, why did Stephen Jay Gould attack how textbooks use Haeckel in 2000? Gould wrote: “We should… not be surprised that Haeckel’s drawings entered nineteenth-century textbooks. But we do, I think, have the right to be both astonished and ashamed by the century of mindless recycling that has led to the persistence of these drawings in a large number, if not a majority, of modern textbooks!” (emphasis added) Similarly, in 1997, the leading embryologist Michael K. Richardson lamented in the journal Anatomy and Embyology that “Another point to emerge from this study is the considerable inaccuracy of Haeckel’s famous figures. These drawings are still widely reproduced in textbooks and review articles, and continue to exert a significant influence on the development of ideas in this field.” (emphases added)

Here is a link to the peer-reviewed journal Science, where there is an article talking about the fraudulent embryo drawings. Yes – the drawings really are fraudulent.

And finally, Casey Luskin has a new post up at Evolution News that lists all the textbooks that contain the fraudulent drawings. One is dated 2013! The drawings just keep getting recycled over and over as a “proof” of evolution.

Does a new, distinct human being begin at conception?

Scott Klusendorf posted a public reply to a critic of his debate on the Unbelievable show, which I blogged about yesterday.

The full reply is here, but I wanted to highlight’s Scott’s scientific defense that the embryo is a human being.

He writes:

First, your claim that because biological life is continuous (an “unbroken tree” as you put it), we can’t say when the embryo’s life begins, is demonstrably false. Just because life is continuous between generations does not mean we can’t tell when an individual human begins to exist. The science of embryology points to a clear, non-arbitrary divide between sperm/egg on one hand, and a newly conceived embryo on the other. That is to say, from the earliest stages of development, embryos are distinct human beings. True, they have yet to grow and mature, but they are human nonetheless. Leading embryology textbooks affirm this.

For example, in “The Developing Human: Clinically Oriented Embryology” (Saunders/Elsevier, 2008), Keith L. Moore & T.V.N. Persaud write: “A zygote is the beginning of a new human being. Human development begins at fertilization, the process during which a male gamete or sperm…unites with a female gamete or oocyte…to form a single cell called a zygote. This highly specialized, totipotent cell marks the beginning of each of us as a unique individual.”

T.W. Sadler’s “Langman’s Embryology” (Saunders, 1993) states: “The development of a human begins with fertilization, a process by which the spermatozoon from the male and the oocyte from the female unite to give rise to a new organism, the zygote.”

Embryologists Ronan O’Rahilly and Fabiola Müller write, “Although life is a continuous process, fertilization is a critical landmark because, under ordinary circumstances, a new, genetically distinct human organism is thereby formed” (Human Embryology & Teratology. 2nd edition. New York: Wiley-Liss, 1996).

And then he quotes some pro-choice scholars, including Peter Singer and David Boonin, to make the point:

Contemporary defenders of abortion also reject your claim that we can’t tell when individual life begins. For example, in his book “Practical Ethics” (Cambridge, 1993) Peter Singer—a bioethicist at Princeton University and supporter of both abortion and infanticide —denies your claim the beginning of human life is can’t be known. He writes: “Whether a being is a member of given species is something that can be determined scientifically, by an examination of the nature of the chromosomes in the cells of living organisms. In this sense, there is no doubt that from the first moments of its existence an embryo conceived from human sperm and eggs is a human being.”

Philosopher David Boonin, author of “A Defense of Abortion” (Cambridge, 2002), writes: “A human fetus, after all, is simply a human being at a very early stage in his or her development.”

I tried to space it out a bit to make it more readable. I think what his sources are saying is that when an egg and sperm meet, they create something with a completely different DNA signature than either the sperm or the egg. I think if you have an organism that has human DNA, distinct from the mother and father, and it is developing in a self-directed way (unlike your finger nails, or hair, say), then you have a distinct human life. And I don’t think “because I’m bigger than she is” is an adequate reason to kill that other human being.

I have a rule in my life. Don’t do anything that is likely to get an innocent person killed. Why can’t everyone have this rule? Is recreational pre-marital sex REALLY that important? I don’t think any of the reasons that people give for having sex (self-esteem, pleasure, etc.) are more important than not killing an innocent human being. When little lives are at stake, we grown-ups should all try to control ourselves, so that we don’t harm people who are smaller and weaker than we are. It just isn’t right.
