Paleontology is the study of prehistoric life, including organisms' evolution and interactions with each other and their environments. As a "historical science" it tries to explain causes rather than conduct experiments to observe effects.

General

[edit]

Early humans

[edit]

Homo is the genus that includes modern humans and species closely related to them. The genus is estimated to be about 2.3 to 2.4 million years old, evolving from australopithecine ancestors with the appearance of Homo habilis. All species of the genus except Homo sapiens (modern humans) are extinct. The other extant Homininae—the chimpanzees and gorillas—have a limited geographic range. In contrast, the evolution of humans is a history of migrations and admixture. Humans repeatedly left Africa to populate Eurasia and finally the Americas, Oceania, and the rest of the world.

Paleobotany

Paleobotany

Paleobotany is the branch of paleontology or paleobiology dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and both the evolutionary history of plants, with a bearing upon the evolution of life in general.

Paleozoology

[edit]

Paleozoology is the branch of paleontology or paleobiology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
