Anthro Final Flashcards
Darwinian Evolution
all species share a common ancestor, (change, descent with modification, survival, reproduction, isolation, gradual)
Descent with Modification
species change over time and give rise to new species
Natural Selection
the mechanism by which evolution occurs, increases variation, shift in traits in response to environment
Thomas Malthus
claimed human misery would keep population in check, promote control of marriage and parenthood, though of poor as a burden
Essay on the Principal of Population
Thomas Malthus, claimed that high populations lead to poverty, population control
Reproductive Success
over generations leads to fitness, allow your genes to carry on
Fitness
Ability to have your genes survive over many generations
Malthusian orthodoxy
underestimated earth’s carrying capacity, promoted population control
Cultural Evolutionists
Edward Tylor, Lewis Henry Morgan, Herbert Spencer, unilineal evolution and evolution of culture as an organism
Unilineal Evolution
evolution of culture and society as an organism (savagery, barbarism, civilization)
Edward Tylor
British Quaker, first professor of Anthropology at Oxford, evolution of religion in stages, argued increased rationality
Lewis Henry Morgan
American Lawyer, ethnical periods (savargy, barbarism, civilization)
Herbert Spencer
Survival of the Fittest, self-taught, the social organism, misquoted Darwin
Survival of the Fittest
most adjusted organisms will have greatest fitness
Social Darwinism
growth of laissez-faire capitalism, justified war and eugenics
Francis Galton
father of hereditarianism/eugenics, eminent man, ranked races by intelligence, proposed social intervention
Eugenics
studying human reproduction in order to increase occurrence of heritable, desirable characteristics
Gregor Mendel
different gene forms are alleles, law of segregation, law of dominance, punnet squares
Genotype
the set of genes an organism carries
phenotype
observable characteristics
law of segregation
only one of two gene copies in a parent is passed to offspring
law of dominance
only the dominant trait will exist as the phenotype
Continuous Trait
traits in which variations are distributed on a continuum
discontinuous traits
traits that may be placed into discrete categories
Ronald Fisher
genes may be influenced by the environment
Complex traits
phenotypes that are controlled by two or more genes
Chromatin
form chromosomes, packager
Chromosomes
carry genes
homologous chromosomes
pairs of chromosomes in a diploid organism that have similar genes, not necessarily identical, we have 23 pairs
Genes
basic unit of hereditary
alleles
alternative forms of a gene
intron
sequence within a gene that is not expressed in the final RNA product
exon
coding portions of DNA
protein
structural, functional, hormone, regulatory
regulatory genes
control expression of other genes
Homeobox genes
regulates features in early stages of embryonic development, segmentation of embryonic tissue
Positive Eugenics
good genes, reinforced with tax incentives, birth stipends
negative eugenics
reduce undesirable traits, methods such as marriage restriction, sterilization, abortion, and euthanasia
Franz Boas
Father of American Anthropology, cultural relativism and holism, mind of the primitive man
Racial Stereotypes
root of ethnic conflict, beliefs about an entire group of people
