Answer #1

Ans) The formation of new species by the accumulation of changes due to much reduced gene flow when the species are geographically separated as a result of which the species starts adapting to different geographical niche and as time passes they start to diverge from one another and thus they are reproductively isolated and ultimately form new species which is known as speciation. If the species can still reproduce and form fertile offspring,this suggests that speciation has not occurred.

Over 20 species of fish have descended from a single common ancestral species. Fossil evidence shows that each of these species evolved when fluctuating water levels totally isolated small sub-populations of the original ancestral species into several different small lakes and prevented interbreeding. Today they are all completely sympatric (all live in the same large lake.) We can identify them all accurately by their morphology. With this evidence, how best can we hypothesize what type of speciation was involved ?...

Most speciation (formation of new species) occurs allopatrically. This means A. new species usually form when one species lives in the same location and same habitat for a long time B. members of one species become separated geographically so that gene flow is stopped between the new populations eventually resulting in enough changes between the populations that they become different species C. a catastrophy causes the formation of a new species by a bottleneck effect D. gene flow between different...

The Northern hard clam and the Southern quahog are two clam species that are normally isolated by environmental tolerances. However, hybridization tends to occur when these species are cultivated in hatcheries as they are kept under the same temperature ranges and sharing enclosures. Which of the following is true? Group of answer choices A. Reproductive isolation between these species of clams is complete. B. Reproductive isolation between these species of clams is incomplete. C. Environmental conditions in their natural habitat...
