Key Evolutionary and Genetic Concepts
Fixism
Belief that all species were created as we see them today. Species are therefore immutable.
Lamarckism
Evolutionary theory proposed by Lamarck. It considers that living beings change throughout their lives as a result of the use or disuse of organs. Body modifications acquired are transmitted to the offspring. Also called evolutionism.
Genotype
The combination of specific alleles of a cell of an individual for the full genome, or more often, a particular gene.

Four Properties
1.
Higher indifference curves are preferred to lower ones.
2. Indifference curves cannot cross
3. Indifference curves are downward sloping.
4. Indifference curves are bowed inward –convexity-
Tangency Condition
MRS = P1 / P2
Consumer’s Optimal Choice
MU1 / MU2 = P1 / P2
Proportionality Rule
MU1 / P1 = MU2 / P2
Perfect Substitutes:
Indifference curves are straight lines. Optimal choice is at one extreme (all of one good).
Perfect Complements:
Indifference curves are L-shaped.
Historical Foundations of Ritual, Protocol, and Power Dynamics
