What were the requirements that Charles Darwin believed were necessary for adaptive evolution? Group of answer choices A. A population contains variation for some character B. The distribution of the character in the population would change over time C. Some variants sruvive and reproduce at higher rates than other D. All of the answers are correct E.

To test evolutionary hypotheses, you make a phylogeny of a group of organisms based on six traits. You suspect tree dwelling evolved to allow for nest building. A В 4 2 E 5 G 3 J 1 = singing 2= nest-building 3 = short legs K 4 4 = hollow snout M - 6 N 5 = crest 6=tree dwelling a) Based on your phylogeny, did hollow snouts evolve to allow singing? Explain your answer. b) Your friend wants to put all of the species that have hollow snouts into a single taxonomic group. Is this a good taxonomic group? Explain your answer. CO

Construct a phylogenetic tree with the species and label the traits according to their number (ex. T1, T2, etc.)
