Metamorphosis

Another Severe Challenge to Darwinian Evolution

Classical evolutionary theory describes how the diversity of plants and animals that we see today developed gradually over time in form and function from a single universal common ancestor. In his book, On the Origin of Species, Charles Darwin reasoned that, just as mankind can develop desirable traits in domestic plants and animals by selectively breeding for these traits, nature can develop desirable traits by a similar process (albeit, undirected), which he called "natural selection" acting on random variation. The key point is that each step needs to provide some increased survival benefit for the individual, or there is no reason to retain it for future generations.

We need to realize that the word...

 

is a (mostly) retired metallurgist. He received a BS in math and physics, before moving into materials science, then finishing with a Ph.D. in metallurgy. He is now spending some free time in exploring some of life’s generally accepted, but poorly supported ideas. For topics in biology, it helps a lot to have a wife who knows biology.

earned a BS in math and chemistry. She worked in the field of molecular biology at the University of Colorado for 15 years, carrying out research in genetics, where she learned a lot about biological systems. After her children were grown, she went on to earn a Ph.D. in biostatistics, thus combining her love for both math and biology. Her interest is in quantitatively modeling biological systems.
