Textbook Question
Chapter 18, Problem 21TYK
SCIENTIFIC THINKING In one of the experiments described in Module 18.13, researchers tested the hypothesis that the highly successful arthropod body plan resulted from new genes that originated in the arthropod lineage. Draw a diagram showing the evolutionary relationship between arthropods and velvet worms and use it to explain why velvet worms were a good choice to test this hypothesis. What results would have supported the hypothesis?

Biology
A colleague has given you a population of avian neural crest cells to use in an in vitro culture system, but that individual keeps poor records and does not remember if the neural crest cells are still undifferentiated. How would you go about testing the cells to determine if they were undifferentiated or differentiated down a particular neural crest lineage? Include your experimental design and any necessary controls you will need to interpret your results.
Which gene family was found to control the development and differentiation of limbs in vertebrate lineages?
A) Hox
B) Sonic hedgehog
C) Noggin
D) Eyeless
Morphological analogs are structures having similar functions but different origins. For example, the wing of an airplane and a wing of a bird are analogous but certainly have different origins. Name and explain the comparisons of THREE ideas that humans have borrowed from plants and animals to use in building structures and making materials.

- Use the information and diagram to answer the following question. In humans, the pelvis and femur are involved in walking. Despite the fact modern whales live in water, they contain a pelvis and femur that are common in land dwelling animals. Based on your observation of the whale diagram and your understanding of evidence that supports evolution, what is TRUE about the pelvis and femur found in living whales today? A. They are newly developed structures found in modern whales due to mutations. B. They are examples of fossilized remains of ancient organisms. C. They are traits acquired by modern whales over time as they adapted to living in water. D. They are vestigial structures which are remnants of structures that served a function in the organism’s ancestors.arrow_forwardWhat Darwin Never Knew.

The similarities suggest that chickens and humans are the direct descendants of modern day fish with tails and gill slits. B. The similarities suggest that vertebrates passthrough each of the adult stages of their evoluntionary history as they develop. C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slitsarrow_forward
