[ 2 ] The term may also refer to excellence in " moral virtue." [ 1 ]
Technically, in a human–animal hybrid, each cell has both human and non-human genetic material. It is in contrast to an individual where some cells are human and some are derived from a different organism, called a human-animal chimera. [1] (A human chimera, on the other hand, consists only of human cells, from different zygotes.)
Human chimera. A human chimera is a human with a subset of cells with a distinct genotype than other cells, that is, having genetic chimerism. In contrast, an individual where each cell contains genetic material from a human and an animal is called a human–animal hybrid, while an organism that contains a mixture of human and non-human cells ...
The linear view of human evolution began to be abandoned in the 1970s as different species of humans were discovered that made the linear concept increasingly unlikely. In the 21st century with the advent of molecular biology techniques and computerization, whole-genome sequencing of Neanderthal and human genome were performed, confirming ...
Biologists classify humans, along with only a few other species, as great apes (species in the family Hominidae).The living Hominidae include two distinct species of chimpanzee (the bonobo, Pan paniscus, and the chimpanzee, Pan troglodytes), two species of gorilla (the western gorilla, Gorilla gorilla, and the eastern gorilla, Gorilla graueri), and two species of orangutan (the Bornean ...

Embryological origins of the mouth and anus. The embryological origin of the mouth and anus is an important characteristic, and forms the morphological basis for separating bilaterian animals into two natural groupings: the protostomes and deuterostomes. In animals at least as complex as an earthworm, a dent forms in one side of the early ...
