Evolutionary Development through Regulatory Genes

Did you know you  share about 85% of your DNA with a mouse? This video provides a description of the field of evolutionary developmental biology and examples of some findings of this fascinating field of science.

Evolutionary developmental biology is a relatively new field  that compares the developmental processes of different organisms to determine their ancestral relationship and to discover how these processes evolved.

‘Developmental  regulatory genes’ tell the body where and how to grow, controlling the identity of different body part. Due to differences in these regulatory genes variations occur in different species; although regulatory genes might tell a growing mouse and a growing human both are vertebrates and require a spine, the regulation of certain genes varies across species.

By studying the correlation between these genes and the growth they cause we can learn a lot about the ancestry  of a species and what its relatives may be.
