Phylogenetics is the scientific discipline concerned with describing reconstructing the patterns of genetic relationships among species among higher taxa. Ontogeny is the developmental history of an organism within its own lifetime as distinct from phylogeny which refers to. First used to refer to speakers of a common language then to denote national affiliations by the 17th century the term race began to refer to physical ( phenotypical) traits.
A race is a grouping of humans based on shared physical or social qualities into categories generally viewed as distinct by society. Human evolutionary genetics second edition pdf. Modern scholarship regards race as a social construct that is a symbolic identity. MEGA is an integrated tool for conducting automatic mining web- based databases, inferring phylogenetic trees, estimating rates of molecular evolution, manual sequence alignment testing evolutionary hypotheses. Ontogeny ( also ontogenesis development of an organism, morphogenesis) is the origination usually from the time of fertilization of the egg to the organism' s mature form— although the term can be used to refer to the study of the entirety of an organism' s lifespan.
Population genetics is a subfield of genetics that deals with genetic differences within and between populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure. Population genetics was a vital ingredient in the emergence of the modern evolutionary synthesis.
