The evolutionary history of an organism is called its ontogeny. This is a study of biology that focuses on the origin of organisms.
A bacteria that moved into a cell and stayed alive.
Charles Darwin's theory of evolution by natural selection related to the origin of structural and physiological adaptations because : Natural selection is when a certain organism adapts to its environment changes . For example , The Box Jellyfish has been existing befor the Dinasours which eventually helps us understand that it adapted to the changes in its environment in order for it to not extinct . It might have become the predator of its habitat or used camouflage to survive .
that all organisms are linked by common ancestry

As far as thousands of years of breeding, evolutionary studies, genetic observations, and common sense are concerned, there is no evidence that cows are of extraterrestrial origin.

The evolutionary order of invertebrate phyla are sponges, cniderians, and bilaterians. The origin of invertebrate phyla begin in the Precambrian times.

The evolutionary theory of the origins of the state emphasizes the government.
Homologous features of animals are a lot more recent in contrast to evolution, where as analogous dates far back. Homologous features are similar in structure, but perform different functions, such as the human hands and dolphin flippers, which makes room to allow recent evolution comparisons while analogous consists of wings of a bee and a bird, which are completely different. When trying to determine evolutionary relationship between two species, biologists concentrate on homologous features, as analogous features would be considered useless in this case.
