As you saw in Part C, the body sizes of sympatric and allopatric P. cinereus and P. hoffmani are consistent with a hypothesis of character displacement resuiting from nformation would strengthen the argument that character dsplacement is in fact responsible for body size avolution in these sawlamander? Which of the following observations would support the hypothesis that Plethodon salamanders did indeed experience character displacement for body size? A) The resouroes used by both species of salamanders are avaisble in limited supply B) Body size is a hertable trait in salamanders Salamanders that are closer in body sine compete less strongly for food C) The sympatric salamander popuiations evolved their present body sizes ater they became sympatric D) In sympaic popuations, saler P cinereus afults survive better and reproduce more

A) The resources used by both species of salamanders are available in limited supply

B) Body size is a heritable trait in salamanders Salamanders that are closer in body sine compete less strongly for food

C) The sympatric salamander populations evolved their present body sizes afterthey became sympatric

D) In sympatric populations, smaller P. Cinereus adults survive better and reproduce more.

All of the above are correct.
