Modern

evolution theory

Molecular evidences:

All living organisms are made of and make use of the same molecules, and all of them use DNA for the storage of their genetic information (genes).

But most important, the more closely related two species are, the greater the percentage of DNA they have in common.

Phylogenetic tree

Comparative embryology

The study of embryos has proven that closely related organisms go through similar stages in their embryotic development.

Paleontological evidence; the fossil record:

Evidence for the evolution theory

Homologous structures and organs

They are anatomical resemblances that represent variations on a structural theme originally present in a common ancestor.

On the other hand analogous structures or organs are those that have a different origin, but carry out the same function

Biological evidence:

When a species undergoes a change in some of its biological characteristics, such as the appearance of pigments in certain butterflies for camouflage.
