nolhlond to sonsblud mont sqrienols What's More Activity 3. Deepening The Concepts Directions: Answer the following questions. 1. How does (a) relative dating and (b) absolute/radioactive dating determine the age of fossils? 2. How does embryology provide evidence for evolution? 3. How do homologous and vestigial structures provide evidence for evolution? 4. What could be possible for some species belonging to the same family to be presently living in various locations on Earth? You can further support your answer with an example.

Imagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?
Carbon-14 dating works for fossils up to about 75,000 years old;fossils older than that contain too little 14C to be detected. Mostdinosaurs went extinct 65.5 million years ago.

If it was incorporated into dinosaurbones, could it be used to date the dinosaur fossils? Explain
Please exaplain 1. One of the explanations for the diversity seen in the fossils corresponding to the Cambrian explosion is the existence of an evolutionary “arms race” between predators and prey. True or False ? 2.Our planet is undergoing such a rapid transition that we may have shifted into a new epoch: the Anthropocene. True or False?

Hello, I need help with number 3 a, b, & c using the diagram below. Pls & thank you! 3. a) What features does the organism shown above have that indicate that it is our direct ancestor among the Cambrian fauna? 3. b) When the organism shown above was swimming in the Cambrian seas, it was very small compared to the apex predator (Anomalocaris), which was several feet long. What adaptations might the organism shown above have to evade predation by Anomalocaris? 3. c) A famous evolutionary biologist says that “everything in evolution is contingent”, which he explains means that events could always have turned out differently. Do you think that the survival of our direct ancestor is an example of a lucky accident that allowed the later evolution of vertebrates, including us? Why or why not? Photos reference: Futuyma, D.

WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.
