NEET BIOLOGY

Detailed explanation-1: -Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.

Detailed explanation-2: -Convergent evolution can be seen in the structurally similar eyes of Squid and humans, in the mobility of worms and snakes with hot legs, and in the wings of bats and birds.

Detailed explanation-3: -In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution.

Detailed explanation-4: -As organisms adapt and evolve, not everything about them changes. The differences, such as the zebra’s stripes, show that each species adapted to its own environment after branching off from the common ancestor. The bodies of deer, moose, zebras, and horses are very similar, and these animals are very closely related.
