molecular pathways that determine different developmental processes operate independently from one another.
morphological differences between species
due to differences in their genomes (what happens due to...?)
Hox gene cluster
provides positional information and control pattern formation in early Drosophila embryos
functional entities encompassing genes and various signaling pathways that determine physical structures such as body segments and legs.
a period of developmental or reproductive arrest that allows the organism to better survive
The capacity of an organism to alter its pattern of development in response to environmental conditions.
Alteration in the timing of developmental events, leading to different results in the adult organism.
A functional entity in the embryo encompassing genes and signaling pathways that determine a physical structure independently of other such modules.
In evolutionary developmental biology, DNA sequences controlling developmental mechanisms that have been conserved over evolutionary time.
Parallel phenotypic evolution
highly conserved developmental genes make it likely that similar traits will evolve repeatedly.
