JMU BIO 150 Exam 2 Define macroevolution ️evolutionary change above the species level, including the origin of a new group of organisms or a shift in the broad pattern of evolutionary changes over time How do we identify a species? ️groups of actually or potentially interbreeding populations that are reproductivley isolated from other such groups Define reproductive isolation ️cannot produce viable offspring Define viable ️offspring can reproduce Define speciation ️splitt...

What is reinforcement? How does it play out? What is it's role in the speciation process? correct answers secondary contact is for selection to "reinforce" existing isolating mechanisms -selection favors the evolution of prezygotic isolating mechanisms -hybrids unfit-> selection favors assortative mating-> mate preferences lead to decline in hybridization -Coyne and Orr: prezygotic isolation evolves faster in sympatric species -mate choice based on toad calls How is reproduct...

BIOL 3040 STUDY GUIDE II, PART A Chapter 4 Synapomorphy: A character or trait that is shared by two or more taxonomic groups and is derived through evolution by a common ancestor. Homoplasy: Correspondence between parts or organs acquired as a result of parallel evolution or convergence. Homoplasy is analogous and can be due to convergent evolution 1. According to the tree below: a Species B is more closely related to species G than species A b Species B is equally related to specie...
