Macroevolution is a large-scale evolutionary change, that usually occurs over long periods of time, and leads to formation of a new species. There are four major evolutionary patterns: 1. evolution a. Sympatric speciation b. Allopatric speciation c. Adaptive radiation - a special case of allopatric speciation 2. evolution 3. 4.

Macroevolution is a large-scale evolutionary change, that usually occurs over long periods of time, and leads to formation of a new species. There are four major evolutionary patterns: 1. evolution a. Sympatric speciation b. Allopatric speciation c. Adaptive radiation - a special case of allopatric speciation evolution 2. 3. 4. 1. Divergent Evolution Divergent evolution occurs when an ancestral species separates into that evolve and then over time become new species. Usually a occurs that causes natural selection to select for different_ . Ex. the penguins in the tropical Galapagos are a different species than the Antarctic Emperor penguins due to adapting to different_ and Processes for divergent speciation The processes for leading to divergent speciation are: A. Sympatric speciation occurs when gene flow is altered by ........: like in plants, |||| Ov bacteria or algae. Polyploidy occurs when the number of chromosomes in one generation due to A species. Ex. Polyploidy in new species forms_ Phlox flowers. Polyploidy forms a new species in one generation! B. Allopatric speciation occurs when a population is into that evolve into Salamander Calfuma different species. Ex salamanders on different sides of the Rocky Mountains.
