Detailed explanation-1: -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-2: -Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved.
Detailed explanation-3: -Anatomical evidence of evolution focuses on similarities and differences in the body structures of different species. Comparative anatomy is the field of study dedicated to this. Similarities in anatomical structures of different species signify that the two species have a relatively recent common ancestor.
Detailed explanation-4: -A body plan is a suite of characters shared by a group of phylogenetically related animals at some point during their development. The concept of bauplane, or body plans, has played and continues to play a central role in the study of evolutionary developmental biology (evo-devo).
