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? Speci...

1. What is microevolution? - a population's gene pool over a succession of generations; evolutionary changes in a species over a relatively brief period of geologic time 2. What is macroevolution? - evolutionary change above the species level, including the origin of evolutionary novelty and new taxonomic groups and the impact of mass extinctions on the diversity of life and its subsequent recovery 3. What is a species? - a group of populations whose members possess similar anatomical cha...
