Your Inner Fish – Chapter 6

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?

Origins of Life: General RNA Polymerases

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

Recent Origins of Life Research

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

Origins of Life – Amino Acids and the Triplet Codon

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

Origin of Life – RNA Self Replicators

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 – Darwin’s Little Warm Pond

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

Origins of Life – Can RNA Spontaneously Assemble?

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

Origins of Life – What are the odds?

I hope to make this the first in a series of posts about current (relatively) origins of life research.  The reasoning behind this is two-fold.  The first is because I’m curious and the blog provides an opportunity to share what … Continue reading
