1) The Life Cycle-- tracing the development of a baby from the fetus stage to old-age adulthood.

2) The genetic "evolution" of human natural selection that gives rises to the different "races" of people, which is really variations (with the emphasis on phenotypical variations) within human kind. There is nothing beyond this, as ameobas to man type of macro-evolution is not only a philosophical story, it is also not well supported scientifically. This belief is, therefore largely assumption and less scientific.

I'm not sure why the questioner limits the number of processes of evolution to just two. It is well known that populations can change due to migration, mutation, genetic drift (small populations), natural selection, and non-random mating. Any of these, alone or in combination, can result in changes in allele frequencies in populations (i.e. in evolution).

What is the next stage of human evolution called?

The next stage of human evolution is called homo sapiens sapiens. More accurately, evolution has no "stages". Species names are merely labels attached to a particular morphotype - and since morphologies are continuously changing, must be considered arbitrary. Although the force of natural selection is greatly reduced in the human species, we are still evolving. However, predicting what direction our evolution will take requires the consideration of so many factors that it can't really be done.


What are subdiciplines used to understand human evolution?

Subdisciplines used to understand human evolution include paleoanthropology, genetics, archaeology, paleontology, and primatology. Each of these fields provides unique insights into the origins and development of humans through the study of fossil evidence, genetic analysis, ancient artifacts, and the behavior of closely-related species.
