Question 1. Based on figure 4.1, is it correct to state that we understand deep relationships among Eukaryotes? How do we represent ambiguity in branching pattern on phylogenetic trees? Hint: look at figure 1.27. No, we cannot say we understand deep relationships among Eukaryotes because there is a polytomy that represents ambiguity on the phylogenetic tree. No, you cannot define deep relationships amongst eukaryotes because the nodes include polytomies which signifies ambiguity/indefinite...

If chimpanzee and human genomes differ only about 1.3% at the level of DNA base pairs, how can we explain dramatic differences in appearance, behavior, cultures, and so on between humans and chimps?Important difference exist in the expression of the genes in the humans and chimps The primary process responsible for the adaptive modifications that occur in populations of organisms over geological time isNatural Selection The wing-ed-ness of a bat wing and hummingbird wing are probably products ...
