NEET BIOLOGY

Detailed explanation-1: -Evolutionary developmental biology (Evo-Devo) as a discipline is concerned, among other things, with discovering and understanding the role of changes in developmental mechanisms in the evolutionary origin of aspects of the phenotype.

Detailed explanation-2: -Evolutionary developmental biology (evo–devo) is that part of biology concerned with how changes in embryonic development during single generations relate to the evolutionary changes that occur between generations. Charles Darwin argued for the importance of development (embryology) in understanding evolution.

Detailed explanation-3: -One of the examples is the study of feathers to elucidate the origin of birds/flight. Other examples include flowers and the origin of land plants, wings and the origin of insects, and shells and the origin of turtles. These features have provided the theoretical basis of evo-devo studies.

Detailed explanation-4: -Developmental changes, as well as new genes, may help explain, for example, how some hoofed mammals evolved into ocean-dwellers, how water plants invaded the land, and how small, armored invertebrates evolved wings.

Detailed explanation-5: -An evolutionary developmental perspective posits that an extended childhood is necessary to acquire the skills needed for the complexities of the human social world.
