Patterns in the distribution of living and fossil species tell us how modern organisms evolved from their ancestors.. The Problem . (in case you’ve forgotten). It is difficult to make a document/presentation “accessible”. It must be formatted in a certain way in order to allow accessibility applications to ‘read’ it. Leonard Brand.

Evaluate the current state of the evidence for the evolution of life forms by random mutation and natural selection. B. iology . E. vidence. Leonard Brand, PhD. Professor of Biology and Paleontology.

Evidence for evolution can come in the form of anatomy and physiology. For example vestigial, analogous, and homologous structures. . Vestigial Structure:. The concept of vestigiality applies to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species. An example is the human appendix..
