Humans share several features with salamanders. Certain genes and proteins are nearly identical between the two species; both sp
ecies have four limbs with a similar skeletal structure; the species' early embryos are similar; and where the salamander has a functional tail, humans have a vestigial tailbone. In evolutionary terms, these are examples of _______
Homology refers to the presence of similar or shared body structures, body parts, gene sequences, proteins, etc. among various lineages. It represents divergent evolution of these lineages from a common ancestor.
Presence of various similar structures in human and salamander reflects the fact that these two species have shared a common ancestor during their evolution. The shared ancestry between human and salamander led to the presence of various homologous body parts and identical gene sequences in them.
It is the main organ that regulates nutrients and sugar flow in the blood. That is why diabetes and other diseases most commonly occur in the pancreas.
