Which inference is the most likely explanation for the universal properties of the genetic code?
O A. Other, less useful, versions of the genetic code were eliminated gradually throughout the course of evolution
OB. The genetic code evolved very early in the history of life, and it was used by an ancient ancestor of all or nearly all living things
O
C. The genetic code evolved relatively recently in bacteria and then it quickly spread to all living things in all evolutionary lineages.
OD. The genetic code evolved early in the history of animal evolution, and then it quickly spread to all other living things in other
evolutionary lineages.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
