Burial of the dead: homo sapiens are the only ones who do so, demonstrates some sort of abstraction. Defines a scientific strategy of using multi[le, independent methods to test a theory. Converging evidence is particularly important for investigations of evolution because of the inherent limits to experimentation. Is there an agreement between fossil record and: dna matching, hemoglobin matching, albumin matching, transferrin matching. Differences in the chain of amino acids of hemoglobin. Human horse: 43 differences: common ancestor is way back in time, mutations in evolution. Methods for investigating evolution from a biological perspective include the fossil record, carbon dating, genetic analysis, and immunological comparisons across species. Animals are selectively bred for their behaviors: genetics has some sort of control on behavior/personality.
