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...

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...

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...

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 po...

bio 181 exam 1 (kosal)Compare and contrast the different mechanisms of speciation (allopatric, sympatric, parapatric, peripatric). - correct answer -Allopatric speciation takes place when populations are geographically isolated. Volcano explodes and populations are divided. -Sympatric occurs without geographic isolation. Occurs through the process of polyploidy: producing individuals with more than two sets of chromosomes. It is a genetic change within a population. -Parapatric speciation ...

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...
