BIOL 1001 Chapter : Bio Notes Ch. 1
Document Summary
Organism with certain inherited traits survive and reproduce better than others in a particular environment. Organism that best meet environmental challenges leave the most offspring. Structures, physiological processes, or behaviors that aid in survival and reproduction. May fit in one environment but not in another. Humans often accelerate the rate of environmental change since advantageous mutations are relatively rare, human activities often drive extinction. Diversity of habitats coupled with selection produce species variety or species richness. Can be studied at diff levels biologist classify organisms based on their evolutionary relationships cells share common features. Three major groups or domains: bacteria (prokaryotic, archaea (prokaryotic, eukarya (eukaryotic) Systematic inquiry- through observation and experiment-into the origins, structure, Prokaryotic (before nucleus) biologists use a binomial system according to the figure, which group of organisms is most closely related to humans? assuming each of the following species names is spelled correctly. Biologists test hypothesis using controlled experiments experiments must science is useless unless communicated.
