In Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes. Scientists found the remains of a large organism that had no resemblance to any current form of life on Earth. The organism also had no resemblance to any fossils ever found, including the very few fossils ever recovered from Vuvatu (fossils are rarely ever found in Vuvatu since volcanic landscapes are generally not conducive of fossilization). The world buzzed with the possibility that this was a crash site for an extraterrestrial body. An extensive study of the uncovered remains was conducted by many research facilities. Their conclusions regarding the organism’s features are listed below: Physical features: The organism has a surprisingly soft and malleable exoskeleton that reflects ambient light, creating mesmerizing patterns. In fact, the remains highly suggest that most of its body parts are soft and blubbery rather than rigid. Habitat: Given its relationship with…
1. Contrast homology and analogy. Give an example of homoplasy. 2. Discuss adaptation and preadaptation. 3. Compare and contrast divergent, convergent, parallel, and organic evolution. 4. What is a vestigial structure? A rudimentary structure? 5. Describe heterochrony – specifically paedogenesis, neoteny, and paedomorphosis.

Genetic diversity 1. Why do multicellular organisms have two copies (alleles) of any given gene? 2. What genotype(s) will result in a dominant phenotype, and why? 3. What genotypes(s) will result in a recessive phenotype, and why? 4. What do mean by the “gene pool” of a population? And why is this such an important concept inunderstanding how evolution works on small scales?5. If p = 0.75, what does q equal? And how do you know this? 6. What does it mean to say that a population has been become “fixed” for a particular trait? Whatvalues for p or q tell us that fixation has occurred? 7. Ultimately, why are we concerned about the loss of genetic diversity (i.e., fixation)? 8. Contrast natural selection with genetic drift. Which one is always adaptive? Explain your answer. 9. What’s the bottleneck effect? Describe some examples of organisms that have experienced this &what caused it to occur. 10. How can gene flow help to restore variation that may have been lost through bottleneck…
Question 2U Which is NOT an example of homoplasious characters? A More than one of these. B Bats and birds are both monophyletic groups with wings. Many species of insects, amphibians, and fish have evolved red and yellow warning coloration to advertise their poisonous skin or organs. Sharks and dolphins have fins and fuselage-shaped bodies, despite sharing a distant common ancestor. E) The amniotic egg is a synapomorphy of terrestrial vertebrates, but has been lost in many groups. Do you have additional content? You can add text, images, and files that support your answers.

Evolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related? O A. Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous. O B. All prokaryotes and eukaryotes use DNA to carry their genetic information. OC. Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease. O D. Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to each other. O E. The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins. «< Question 5 of 120 A Moving to another question will save this response. 11:51 AM 12/16/202 End F10 pgUP F11 PgDn F12 Home PrtScn F8 DII F5 F7 F6 F3 F4 F2 & #3 2$ 7 8 9.…
