Larvae and Evolution


Add your own review!

Overview

This is an explanation of the major anomalies between adults and their larvae in many groups of animals, presenting evidence for a non-Darwinian type of evolution taking place alongside Darwinian evolution. The author's thesis is that at various points in the evolutionary time - quite rarely, but often enough to effect major changes in the direction of evolution - organisms captured genes from distantly related organisms. These genes were then incorporated into the genomes of the host organisms, where they are expressed in larval or juvenile stages, but not in adults. These are explained by presenting a number of widely known and otherwise unfathomable incongruities between larval stages and corresponding adults.
