Morphology (biology) is the study of the form or shape of an organism or part thereof.

Comparative anatomy is the study of similarities and differences in the anatomy of organisms. It is closely related to evolutionary biology and phylogeny (the evolution of species).

Two major concepts of comparative anatomy are:
1. Homologous structures - structures (body parts/anatomy) which are similar in different species because the species have common descent. They may or may not perform the same function. An example is the forelimb structure shared by cats and whales.
2. Analogous structures - structures which are similar in different organisms because they evolved in a similar environment, rather than were inherited from a recent common ancestor. They usually serve the same or similar purposes. An example is the torpedo body shape of porpoises and sharks. It evolved in a water environment, but the animals have different ancestors.

The rules for development of special characteristics which differ significantly from general homology were listed by Karl Ernst von Baer (the Baer laws).

History
Edward Tyson is regarded as the founder of comparative anatomy. He is credited with determining that marine mammals are, in fact, mammals. Also, he concluded that chimpanzees are more similar to humans than to monkeys because of their arms.

in the event that they wanted peace they could try this - yet as all of us be attentive to they do no longer desire peace with Israel at any time interior the destiny. Hamas has the function of agitator indiscriminately focused on Israel to impact retaliation which then become the fault of Israel. Hamas is in accordance with hate for Jews and their supporters interior the midsection East and someplace else help and inspire this hatred. Hamas is the violent equivalent of the folk who write poisonous lies approximately Israel and Jews - the point of the two communities is to break Israel using violence or fake propaganda. most of the folk who try this fake propaganda could deny their hatred of Jews and say this is in simple terms Israel's movements they dislike. yet whilst Arab Muslims dedicate atrocities against Christians and Africans in Darfur it extremely is disregarded.
