Detailed explanation-1: -Of which pattern of macro-evolution is this an example? Ostriches and giraffes are both native to the savannahs of Africa. They share the same characteristic of a very long neck. Also called adaptive radiation.

Detailed explanation-2: -Examples of convergent evolution include the relationship between bat and insect wings, shark and dolphin bodies, and vertebrate and cephalopod eyes. Analogous structures arise from convergent evolution, but homologous structures do not.

Detailed explanation-3: -Mammals. Several groups of ungulates have independently reduced or lost side digits on their feet, often leaving one or two digits for walking. That name comes from their hooves, which have evolved from claws several times. For example, horses have one walking digit and domestic bovines two on each foot.

Detailed explanation-4: -In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities. VLRs and TCRs/BCRs both serve as antigen receptors, but are evolutionarily unrelated.
