Document Summary

Pattern-how things are in nature/statement summarizing observations eg. for special creation: species created independently of one another, don"t change. Process-produces that pattern/set of observations eg. for special creation: instantaneous and independent creation of orgs. by god. Plato claimed organisms made perfect by god, unchanging. Aristotle ordered organisms into ladder of life/chain of being-more big & complex at top. Lamarck: species change, evolve from lower ladder species to higher better ones. Darwin & wallace: variation among individuals very imp, not linear like ladder idea. Theory of evolution"s pattern claimed: 1) species change thru time 2) related. Fossil-any trace of an organism that lived in the past (eg. bones, shells, tracks, dung) Extinction: darwin said because array of species has changed through time. Transitional form-fossil species with traits intermediate btwn old & younger species. Law of succession: extinct species succeeded by similar species (they"re related) eg. fossils show whales used to be land/h20 creatures w/ limbs, now h20 & no limbs.

Biological evolution is the process whereby earthâs life changes over time through changes in the genes of populations of organisms in succeeding generations. Species have evolved from earlier, ancestral species through natural selection. Discuss this process in detail. Why is this beneficial for species? Why do you think there is controversy about human evolution?

In evolution, why is it important that individuals vary from each other?

	A.	Variation allows some individuals to do better than others, so those variations are selected for.
	B.	If variations or mutations are extreme enough, new species can result.
	C.	Variations are important because individuals have to change through time.
	D.	Variations are important because they're inherited.
	E.	Variation gives every individual an equal chance of surviving so they can be selected for.
