In 1995, a hurricane deposited a collection of uprooted trees and leaves on the
eastern beaches of the island of Anguilla in the Caribbean. The vegetative matter
likely came from Guadaloupe, an island a few hundred miles away. Approximately one
dozen green iguanas, which were native to Guadaloupe but had never been seen on
Anguilla, were observed emerging from the vegetation deposited on the Anguilla
beach. Over the past 20 years, the iguanas on Anguilla have been diverging
genetically from the original Guadaloupe population through genetic drift. If the two
populations become two new species, the most likely method would be____ speciation
by means of _____.
Give this one a try later!
allopatric; dispersal
Allopatric (Occurs in small populations that are physically isolated)
Dispersal (Individuals migrate from one area to another)
, An adaptation is a feature that:
Give this one a try later!
increases the chance that an individual will reproduce
The movement of a genotype into or out of a population is called:
Give this one a try later!
migration
What is the name of the major clade of life that is the sister taxon to Animalia?
Give this one a try later!
Choanoflagellatea
In the diagram above, what is the sister taxon above, what is the sister taxon (closest
living relative) of the squirrel monkey?

capuchin monkey
