The Best-Laid (Body) Plans Humans, indeed all tetrapods, have 1 head, 4 limbs arranged in two pairs, a tail, and a variety of other gross morphological features. Why? And more interestingly, where did this basic body plan come from?
Yesterday, I discovered a new set of studies that I had not previously known about. I may write about all of them, but I definitely want to talk about this particular study for two reasons. The first reason is that … Continue reading
In 2008, the International Society for the Study of Origins of Life, held a symposium on the origins and early evolution of life. 350 scientists from all over the world came together with more than 310 presentations. The journal Origins … Continue reading
One question that always seems to come from the anti-science crowd when discussing the origin of life is, “Where did the genetic code come from?”. Scientists will often point out the simple fact that every living thing on the planet … Continue reading
We have previously established that organic compounds, including nucleotides, are trivially easy to produce from inorganic sources. We have also established at least two methods from which long chain RNA molecules could develop without organic processes… including one that requires … Continue reading
Origins of life is a tricky business. We can’t know how it happened. We weren’t there and chemical reactions and molecules just don’t fossilize well. The point is not to show how it happened. Likewise, the point is not (necessarily) … Continue reading
We know that it is almost trivial for inorganic compounds to spontaneously react to form organic compounds. We can see this in hundreds, if not thousands of similar experiments since Miller-Urey. We can also observe these organic products in places … Continue reading
