or DNA molecule.
Adaptation
getting use to something.
Species
A group of organism that are closely related and can
mate to produce fertile offspring.
Evolution
a process of inherit characteristics within a population change over generations such the new species sometimes arise.
Fossils

Selective Breeding
The human practice of breeding animals or plants that
have certain desire characteristics.
Natural Selection
The process by which individuals that are better adapted to their environment survive and reproduce more successful than less well adapted individuals.
Generation Time
The period between the birth of one generation and birth of the next generation.
Speciation
The formation between animals of new species as a result of evolution.
Primates
A type of mammal characterize by opposable thumbs and binocular vision.
Hominid
A type of primate characterize by bipedalism relatively long lower limbs and lack of a tail.
Homo sapiens
The species of hominid that includes modern humans and their closest ancestors and that first appeared about 100,000 to 150,000 years ago.
