Quick Summary

Evo-devo, short for evolutionary developmental biology, is a field that merges evolutionary and developmental biology. It investigates how changes in developmental processes drive evolutionary diversity. This science explores the mechanisms behind the vast array of organic forms we see.12

Evo-devo has prompted new thinking on long-standing evolutionary questions. A key area of study involves homeotic genes, which contain a DNA sequence called a homeobox. These genes are crucial for directing cell development into specific body parts during embryonic stages. Mutations in these genes can lead to significant developmental alterations, illustrating the link between genetic changes and evolutionary outcomes. The development of an organism often retains features from its ancestors, as evolutionary changes typically build upon existing structures and processes.1345

Many researchers in evo-devo argue that nature imposes certain general constraints on the ways in which organisms may develop, and therefore natural selection, the means by which function determines form, does not…
