This Concept Map, created with IHMC CmapTools, has information related to: Development Wyatt Ch 3 092618, bonding with the newly born lamb with the adaptive function / current utlity, DNA (genetics / heredity) for example FoxP2 Gene, "for" individuals with "adaptations" leading to "well adapted" populations (but not "perfectly adapted" populations, more testosterone that stimulates male reproductive devleopment, Imprinting which allows ducklings to learn from their mother, releasing testosterone that in turn, stimulates the hypothalamus to secrete hormones, Imprinting requires ????, the development song in young birds that sing (not all birds sing) but for which "exon 7" (expressed codon 7) seems to be unique for each of these groups (humans; whales & dolphins; birds) (which could lead to slightly different proteins in the 3 groups) (Webb & Zhang 2005), Gene Expression for example in reptiles, FoxP2 Gene determining song-learning in non-human mammals (whales & dophins), whether an individual becomes male or female (interestingly, we all start out embryologically as females) by releasing testosterone, a release of the hormone "oxytocin" leading to bonding with the newly born lamb, the adaptive function / current utlity being increased survival of the ducklings, female sheep giving birth during which the expanding vagina & cervix, signals to the pituitary to release more testosterone, The development (ontogeny) of an animal's behavior with Natural Selection, Imprinting which allows ducklings to immediately follow their mother after hatching (these are "precocial" birds), ducklings to learn from their mother by mimcking her actions, Internal Genetic Factors (3) ("Nature") including DNA (genetics / heredity), The "SrY" gene (turned on early in development in mammals) determines whether an individual becomes male or female (interestingly, we all start out embryologically as females)
