)Approximately how far back in time does the fossil record extend? 3.5 million years 5.0 million years 3.5 billion years 5.0 billion years -) How could the duplication of the Hox gene complex help facilitate animal adaptive radiation? The new gene copies helped facilitate the evolution of more complex body plans. The new gene copies helped facilitate the evolution of smaller bodies. The new gene copies led to lower metabolic rates. It is unlikely that gene duplication events in the Hox complex played a role in the adaptive radiation animals. ) Whatever its ultimate cause(s), the Cambrian explosion is a prime example of mass extinction evolutionary stasis adaptive radiation a large meteor impact

Consider the following sample dataset of character traits for five taxa (A, B, C, D, and E) and an outgroup (O) and answer the following: Taxon, Character 1 A B C D 1 1 1 0 0 Character 2 0 0 0 1 1 0 Character 3 1 1 0 0 0 0 Character 4 1 1 1 0 0 0 (A) Identify which character traits are ancestral and which are derived, (B) Determine the two taxa most closely related to each other (C) Are any of the character traits obvious homoplasies? If so, which ones? (D) Name three taxa that if put in their own taxonomic group would be considered paraphyletic.
Species A and B have long wings, whereas species C has short wings. Which of the following pieces of evidence would best support the hypothesis that long wings are a synapomorphy? A. DNA evidence showing that species B and C are sister species B. Fossil evidence showing that the common ancestor of species A, B, and C had short wings C. DNA evidence showing that species A and C are sister species D. Fossil evidence showing that the common ancestor of species A, B, and C had long wings E. Evidence showing that species A and B live in an environment that favors long wings, whereas species C lives in an environment that favors short wings
The phylogentic tree below depicts the evolutionary relationships of the following species A through M.
Researchers studied the effects of artificial selection on largemouth bass. The fish are bred in fisheries to have the desired trait of a high vulnerability rate (HVR) so they are easily caught by human anglers, and then released in artificial ponds and lakes that allow recreational fishing. Within three generations, a fishery can produce a population saturated with members that have the HVR trait in the study. Researchers compared the health of three groups of fish, as measured by the time it took them to recover after exercise: fish with HVR, fish with a low vulnerability rate (LVR), and a control group of wild fish. Each groups' cardiac output, heart rate, and stroke volume are represented in the graph. 85 80 75 70 65 60 55 50 Control LV HV Group of Fish Does the practice of artificial selection in fisheries of largemouth bass for a greater frequency of members with HVR affect the variability in their heart rate, and why? No, artificial selection produces fish with the HVR trait…

Choose True for yes and False for no, for each of the statements 1) If fossil evidence of the most recent common ancestor of A and B (10 million years ago) was found on both sides of the river (that formed 20 million years ago), then the distribution of A and B is best explained by vicariance. True or false 2) Is It possible that species C will speciate ? True or false
Answer with true or false for each statement: A. The Anthropocene is proposed to represent the modern era where human-generated change is extensively modifying global landscapes and climates. b. Theories for the source of common primate characteristics include an arboreal adaptation, and switching the diet from insects to plants and fruits. c. Although there are many bases, DNA ordinarily makes use of only four: guanine and cytocine, and adenine and thymine.
