Humans (primates) show up in the last 5mya, our earliest ancestors reach back to 50mya. Science (a process) understands how things change over time (evolution) and testing processes that change over time. science is always growing, building on new facts/ new discovery disproven. 1859 origins of species book publishes first (given credit) In their studies they noticed these postulates o . Variability in (genetic) fitness (some individuals have advantages over other in a population, genetic fitness = ability to reproduce- healthiest kids) (their genes are best represented in future generations) These ideas led to the theory of natural selection the process by which some individuals have advantages over others (more fit) and will be most represented in future generations. Stabilizing selection the advantages and disadvantages cancel each other (height), norm human height between 5-6 ft.
