Iguanas are living in a relatively dry habitat. genotypes and phenotypes for iguana feet can be seen above. the population of iguanas in the dry habitat contained individuals that did not have webbed feet. over three generations, the phenotype of the iguanas changed although the habitat did not. the ratio of webbed to non-webbed feet changed over time from 100% not webbed: 0% webbed to 50% not webbed: 50% webbed. elaborate on the reason for the change in phenotype within the population

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.
