- 4. As defined above, is a crown group monophyletic? Is a stem group monophyletic? It is sometimes useful to think in terms of stem groups and crown groups because it helps us to place extinct taxa in their appropriate evolutionary context without having to "force" them into a box (e.g., bird-like reptiles do not have to be classified as birds, per se). And so, when we discuss extinct taxa in this course, we will sometimes refer to them as being part of a stem group.arrow_forward24.arrow_forward7. How can two species be nearly identical with regard to genotype but very different phenotypically? How can variations in genotype (but not necessarily phenotype) lead to potential speciation?arrow_forward
- 13. A group of birds feed on two different types of algae. The birds that feed on the red algae have a more saturated coloration that those feeding on the green algae. When these birds reproduce, no matter their diet was, their offspring has dull colors. Is this evolution? If yes, explain why and what process is occurring. If no, explain why and indicate the name of the phenom occurring herearrow_forward3) Allopolyploidy involves a.a genetic divergence that results in nonviable offspring. b.a decrease in chromosome number within a single species. c.an increase in chromosome number following hybridization of different species. d.an increase in chromosome number within a single species.arrow_forward3.
