AP Biology Exam Questions and Answers Graded A+ What are the 2 theories of evolution? Explain each Gradualism- geologic changes result from slow, gradual, continuous process Punctuated Equilibrium- Long period of stasis punctuated by short bursts of significant change. What was Lamarck's theory and why was it wrong?

Micro-evolution - Answer-- a change in an evolution's gene pool over a succession of generations - changes in allele frequencies within populations - often associated with adaptation - can be measured from one generation to the next Macro-evolution - Answer-- major changes in the history of life - origin of new species - generates biological diversity Species - Answer-A population or group of populations whose members have the potential to interbreed with one another in nature to produc...

micro-evolution - Changes in allele frequencies within populations, often associated with adaptation, can be measured from one generation to the next "small changes" macro-evolution - Major changes in the history of life, origin of new species, generates biological diversity "big changes" species - -a group of populations whose members can interbreed -produce fertile offspring allopatric speciation - -Species evolve in geographic isolation, usually bc of a geographic barrier -...
