LIFE SCIENCE

Detailed explanation-1: -Lesson Summary. Homologous structures are structures in related species with a common evolutionary origin that have the same form but may hold a dissimilar function.

Detailed explanation-2: -Homologous Structures. The structures derived from a common ancestor or from the same evolutionary or developmental origin are referred to as homologous structures. Homologous structures may not necessarily perform the same function. An example of homologous structures is the forelimbs of humans and bats.

Detailed explanation-3: -Structures that have different mature forms but develop from the same embryonic tissues are called homologous structures. Similarities and differences in homologous structures help biologists group animals according to how recently they last shared a common ancestor.
