The diversity of the living world is staggering.The theory of evolution by natural selection is attributed to 19th century British naturalist Charles Darwin. The theory is widely accepted based on fossil records, DNA sequencing, embryology, comparative anatomy and molecular biology. Darwin’s finches are examples of evolutionary adaptation.Evolution by natural selection occurs when certain genotypes produce more offspring than other genotypes in response to the environment. It is a non-random change in allele frequencies from one generation to the next.

In 1922, Walter Garstang declared that ontogeny (an individual's development) does not recapitulate phylogeny (evolutionary history); rather, it creates phylogeny.

The tree-building process explained above is based on the principle of parsimony. The parsimony principle is basic to all science and tells us to choose the simplest scientific explanation that fits the evidence. In terms of tree-building, that means that the best hypothesis is the one that requires the fewest evolutionary changes.

Recombination DNA changes when chromosomes shuffle, or recombine. This happens normally in the process of making a sperm or an egg. As a result, every new child or offspring inherits a unique assortment of DNA from each parent. Although both children inherited their chromosomes from the same parents, each child got different versions. Selection ….
