Evolution Bug

ArachnidNothing is simple in biology. Monica Young and Paul Hebert of the Biodiversity Institute of Ontario, Canada, have found within the amino acid sequences of eight-legged critters, known as arachnids, an evolution bug.

In one of the most extensive invertebrate amino acid sequence studies to date, Young and Hebert found highly variable patterns of amino acid sequences in the hemeprotein known as cytochrome C between species. None of Charles Darwin’s continuous “successive, slight” evolutionary changes in more than 4,000 species of arachnids studied were found. The paper, published in the highly respected journal PLOS ONE in August 2015, demonstrates a persistent flaw in the theory of natural selection – the absence of a common ancestor.
