Document Summary
Human origins: replacement or multiregional hypotheses: the advent of powerful genetic tools for investigating human origins has contributed much debate. Morphological evidence: morphological evidence for the replacement and multiregional hypotheses centres on whether h. sapiens interbred with contemporaneous congenera, particularly h. neanderthalensis, the replacement hypotheses states that no such interbreeding occurred. These results seemed to support the replacement hypotheses, and led to a flurry of research on the genetics of human origins. Mitochondria: structures in eukaryotic cells that turn nutrients into energy for the cells (i. e. , the power plants of cells). Natural selection and human adaptation: humans exist or have existed in environments ranging from equatorial jungles through scorching deserts to the awesome expanses of the arctic ice shelf. Body size and shape: for example, we range in height from an average of 1. 5 m in the pygmies of central africa to.
