NERVOUS AND ENDOCRINE SYSTEMS
work together to produce all human action
ENDOCRINE SYSTEM: system of ductless glands that regulate body functions through hormones secreted into bloodstream
Consists of hypothalamus, pituitary gland, thyroid, adrenal glands, & gonads (ovaries & testes)

NATURAL SELECTION
Charles Darwin
driving force behind evolution
animals specifically choose mates & produce offspring that will survive environmental conditions…rest will die off

PHENOTYPE VS. GENOTYPE
PHENOTYPE observable physical characteristics inherited by parents (eye color, hair color, height, etc.)
GENOTYPE: Your unique combination of genes (aka: genetic makeup) and the environment you grew up in

GENETIC MUTATIONS
Genes MUTATE to aid survival, BUT also produce troublesome traits (i.e. mental retardation, depression, etc)
