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? Lamarck = Inheritance of Acquired characteristics- traits acquired during lifetime could be passed on What is natural selection Comptetition for limited resources re...

IB Biology: Evolution Questions and Answers Already Passed What is a theory? A comprehensive explanation of some aspect of nature (vs a hypothesis, which is just a prediction as to the result of an experiment). What were some ideas from Darwin's time that influenced his work? French naturalist Buffon in the mid-1700s studied fossils and said the Earth must be older than previously assumed; Lamarck in the early 1800s proposed that life changes over time. Define acquired vs heritab...

Adaptive Radiation - An evolutionary pattern in which many species evolve from a single ancestral species Allele - An alternative form of a gene. Allele Frequency - Number of times that an allele occurs in a gene pool in comparison to the total number of alleles allopatric speciation - The formation of new species in populations that are geographically isolated from one another. allopolyploidy - a species with multiple sets of chromosomes derived from different species Alpha (origination...
