Anthro Chapter 1 notes

Close human relative from 4 mya.

genetic changes in populations over time that can result in speciation (appearance co a new species), especially when those pops are isolated from each other.

genetic alterations in populations that cause populations of a species to differ from one another in frequency of certain traits.

the strategy by which humans adapt to the natural environment. Culture is learned. All humans product of culture raised in. Since behavior is learned it follows that human behavior, perceptions, values, and reactions are shaped by culture. Predisposition to culture is maybe most critical component of human evolutionary history. Even earliest hominins had culture. over time culture influenced many aspects of our biological makeup; and in turn, aspects of biology influenced cultural practices. Long term interaction between biology and culture called biocultural evolution.

the study of patterns of belief and behavior found in modern and historical human cultures. Origins of it in 19th century when travel brought Europeans into contact with other cultures. Study of nonwestern cultures is ethnography. Today focus shifts to urban populations.

the study of human speech and language including the origins of language in general and specific languages. Identify language families.
