Ecological evolutionary developmental biology [c] integrates research from developmental biology and ecology to examine their relationship with evolutionary theory. [78] Researchers study concepts and mechanisms such as developmental plasticity , epigenetic inheritance , genetic assimilation , niche construction and symbiosis .
Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth.
Evolutionary developmental biology is the study of the evolution of developmental processes across different organisms. It is utilized within multiple disciplines, primarily evolutionary biology and anthropology. Groundwork for the theory that "evolutionary modifications in primate development might have led to … modern humans" was laid by ...
In terms of evolutionary developmental biology, heterotopy means the positioning of a developmental process at any level in an embryo, whether at the level of the gene, a circuit of genes, a body structure, or an organ. It often involves homeosis, the evolutionary change of one organ into another.
Toolkit genes are central to the synthesis of molecular genetics, palaeontology, evolution and developmental biology in the science of evolutionary developmental biology (evo-devo). Many of them are ancient and highly conserved among animal phyla.
How the Snake Lost Its Legs: Curious Tales from the Frontier of Evo-Devo is a 2014 book on evolutionary developmental biology by Lewis I. Held, Jr. The title pays homage to Rudyard Kipling's Just So Stories, but the "tales" are strictly scientific, explaining how a wide range of animal features evolved, in molecular detail.
An area of current investigation in evolutionary developmental biology is the developmental basis of adaptations and exaptations. [187] This research addresses the origin and evolution of embryonic development and how modifications of development and developmental processes produce novel features. [188]
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration , asexual reproduction , metamorphosis , and the growth and differentiation of stem cells in the adult organism.
