ANT211H5 Lecture Notes - Lecture 3: Congenital Adrenal Hyperplasia, Cortisol, Dihydrotestosterone
Document Summary
Evolution as modification of developmental processes over generations. Defusing the nature vs. nurture debate: complicated relationship between the two. Sociobiology issue: can"t ignore development, and can"t ignore the environment and its effects, environmental changes and the effects they can have on organisms. Epigenetic perspective: the original structure of the cell changes over time. Gonadal hormones (sex hormones: organizing function, happens in utero, permanent sex difference, activating function, sex differences as developed during puberty, example: the development of breasts in girls. Jost (scientist: he experimented with embryos, removed the testicals from embryos. In the absence of testosterone, female internal and external parts develop: the mullerian ducts stay in tact, in males, testosterone makes the wolfian ducts, the mullerian ducts begin the process of degeneration until they no longer exist. Congenital adrenal hyperplasia (cah: when females are exposed to testosterone, adrenal glands produce androgen instead of cortisol.
