ANTH 011 Lecture Notes - Lecture 25: Peptide, Population Genetics, Wilhelm Johannsen
Document Summary
Example of importance of heredity: universal existence of kin naming systems, which vary from culture to culture. Their very existence in all cultures shows the importance of identifying and labeling groups of people who are linked to one another via heredity. Johannsen did not know what a gene was in biochemical sense, used it to describe the. Something - the particulate unit of inheritance- that was being passed on from generation to generation. Not just information; a part of the essential machinery of the living body. Johannsen also coined terms genotype" and phenotype" (see ch. Blueprint- one cannot unbuild a body as a builder can destruct a building. Recipe- environments in which genes exist cannot be controlled as the environment specified by a recipe can be controlled.
