Isolations
What form of Isolation has a physical separation boundary that stops two species from being able to mate?
Geographical Isolation
What is speciation?
new species forming by evolution of a pre-existing species
What is Divergent Evolution?
different species arising from one shared common ancestor
What is extinction?
Elimination of an entire population
What did Charles Darwin develop?
Natural Selection Theory
What type of Isolation involves the sperm and ova being unable to be compatible?
Gametic Isolation
During speciation what happens to the gene pools?
The gene pools gradually become different, leading to not reproducing with each other UNABLE
What is Coevolution?
two populations of organisms form a relationship where they change in response to each other
Gradualism is slow _______ changes over a ______ period of time
constant;long
TRUE OR FALSE: flowers and insects pollinating them is a type of coevolution
TRUE
What type of Isolation contains differences in mating rituals/ calls - which prevents two species from mating?
Behavioral Isolation
TRUE OR FALSE: Speciation rages anywhere from a few generations to millions of years?
TRUE
What is Convergent Evolution?
unrelated species evolve similar characteristics due to similar environments
Mass extinction occurs when a catastrophic event changes the environment ______ ?
when
suddenly; all of a sudden; abruptly
What species did Charles Darwin study on his mission to discover evolution?
Galapagos Finches
What type of Isolation has different reproductive anatomy that blocks the two species from reproducing?
Mechanical Isolation
What must occur during speciation?
A form of isolation
TRUE OR FALSE: Birds and Pterodactyls are related because they both fly
FALSE, not related but they both fly
What is Gradual Extinction?
a species being eliminated at a slow rate
What is EVOLUTION?
biological change in populations over time that makes the descendents genetically different from ancestors
What type of Isolation seperates two populations from breeding due to different periods of day, season - leading to not mixing gametes?
