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...

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...

What is micro-evolution? - Changes in allele frequencies within populations, often associated with adaptation, can be measured from one generation to the next "small changes" What is macro-evolution? - Major changes in the history of life, origin of new species, generates biological diversity "big changes" What is a species? - a group of populations whose members have the potential to interbreed with one another in nature to produce fertile offspring What is allopatric speciation? - ...

Convergent vs Divergent Evolution - ANSWER -Divergent: one broad class but because of different features they diverge -Convergent: similar features between 2 different classes Punctuated Equilibrium vs Gradualism - ANSWER -Punctuated: concrete & defined phenotypes -Gradualism: phenotypes gradually evolve Speciation - ANSWER Formation of new species 1) Allopatric: separated by geographical barrier (mountain, ocean, river) -Barrier divides species 1 and species 2 2) Parapatric...

Natural selection - ANSWER Process that determines which individuals will pass on their genes to the next generation Evolution - ANSWER the changes that we see in the genes and characteristics displayed by successive generations of a population Speciation - ANSWER the production of a new species from a previously existing species Allopatric speciation - ANSWER separated by land Sympatric speciation - ANSWER speciation in the same area; exploiting unused resources causes them to becom...

BIOL 112 FINAL EXAM REVIEW WITH COMPLETE SOLUTIONS Darwin’s theory of evolution is a strong theory, but at the time of proposing the theory, some aspects were yet to be explained. Which of the following things below did Darwin understand and incorporate into his theory? a. That inherited variations could increase an organism's ability to survive and reproduce b. How chromosomes were inherited c. That genetic mutation could be responsible for making new alleles d. That genes were t...

What is microevolution? - The change in allele frequencies that occurs over time within a population. What is macroevolution? - Major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. What is a species? - A group of populations whose members possess similar anatomical characteristics and have the ability to interbreed. What is allopatric speciation? - The formation of a new species in populations that are geographi...
