Evolutionary developmental biology

Definition

Evolutionary developmental biology is the comparative study of organismal development and how it has evolved. There is a particular focus on the genetic basis of phenotypic structures, how they change during evolution, and how novel structures arise.

    A focus on sea anemones throws the classic concept of germ layer homology on its head, as cnidarians are found to possess the gene expression programmes for three, rather than two, germ layers.

    Species-dependent regulation of plexin A1 signalling may underlie the elimination and retention of cortico–motor neuronal contacts in developing mice and in developing primates, respectively.

    Three new bivalve genomes are resources for comparative genomics over broad timescales, providing a glimpse into the evolution of understudied marine animals and their adaptations to extreme environments.

    Morphology and gene expression in mid-embryogenesis are highly conserved across species of the same phylum. In nematodes, developmental constraints, rather than natural selection, explain how this pattern was established during evolution.

    Biologists have long been captivated by bats, whose unique adaptations are wonders of evolution. We examine some of the many reasons why they are so important to ecologists and evolutionary biologists.

    Bat species that echolocate using signals from their larynx, and those that do not, all share a similar pattern of inner ear development that is distinct from other mammals, implying a single evolutionary origin of laryngeal echolocation.
