Document Summary
Charles darwin"s theory of evolution: main points of origin of species. Survival and reproduction: potential for rapid reproduction + constant population size . Competition for survival: competition for survival + variability in structures and behavior + some inherence of variability natural selection: on average, organisms best suited to an environment leave the most offspring. Evolution: a change in the allele frequency of a population over time: natural selection + variability evolution, most famous stop: galapagos islands, genetic composition of population changes (evolves, differential survival (natural selection) Selects advantageous adaptations: the more time, the more change, eventually become much different. What is science: the observation, identification, description, experimental investigation, and theoretical explanation of phenomena. Theory: such activities restricted to a class of natural phenomena, hypothesis: tentative explanation of observations, theory: general explanation of natural phenomena, developed. Educated guess. through extensive and reproducible observations.
