Question

How can we say that vertebrates heart show divergent evolution

Answer 1

Divergent evolution or divergent selection is the accumulation of differences between closely related species populations, leading to speciation. Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation) and experience different selective pressures that drive adaptions to their new environment. After many generations and continual evolution, the populations become unable to interbreed with one another.[1] The American naturalist J. T. Gulick (1832-1923) was the first to use the term "divergent evolution",[2]with its use becoming widespread in modern evolutionary literature. Classic examples of divergence in nature are the adaptive radiationof the finches of the Galapagos or the coloration differences in populations of a species that live in different habitats such as with pocket mice and fence lizards

Answer 2

Function of Vertebrates Heart

Explanation:

• In vertebrate animals, the heart is an hollow muscular organ that capacities to pump the blood through the circulatory system.
• It can contain up to four chambers (just like the case in warm blooded animals and birds, including humans, and it works by musically contracting and dilating
• Blood passes in grouping through the ventricle, and conus arteriosus,sinus venosus and atrium
• The ventricle is the principle siphoning chamber, all things considered in the hearts of all land vertebrates
