Chapter 33, Problem 9TYU
FOCUS ON EVOLUTION
The human esophagus and trachea share a passage leading from the mouth and nasal passages, which can cause problems. After reviewing vertebrate evolution (see Concept 21.4), explain how descent with modification explains this “imperfect” anatomy.

Embryos go through various stages that suggest the animal’s evolutionary process. Embryos are frequently fossilized and illustrate change over time. Embryos provide evidence for which life forms existed at the same time. Embryos contain the code for all life on Earth.arrow_forward

- Regents Practice: Base your answer to question 1 on the information below. Ten years ago, scientists discovered a well-preserved set of dinosaur remains in China. This dinosaur, which walked on Earth about 125 million years ago, had feathers and was about the same size as a turkey - but don't be fooled. This dino's bite was a lot worse than a turkey's gobble. After a close (and careful!) examination of the dino's teeth, scientists recently concluded that this dinosaur was probably poisonous. The study was led by David Burnham, who works and teaches at the University of Kansas in Lawrence. Source: www.sciencenewsforkids.org 1. State one inference that could be made based on the fact that this dinosaur had feathers. 2. Extension Activity: Evaluate the different types of evidence supporting evolutionary relationships between species. Which type of evidence do you think provides the most support for evolution today? Justify your response. Evidence:arrow_forwardGive at least 10 exoskeletons found in animals, source, its description and state their embryonic origin.

How does the anatomy of the digestive system influence the food preference of the perch, compared to that of the shark? What is the comparison of both the shark and the perch in their buoyancy mechanisms and their oxygen/carbon dioxide exchange?

- Mammals have a particularly good sense of earing thanks to their inner ear which includes three tiny bones. Reptiles, in contrast, have a single inner ear bone. The lower jaw of reptiles is composed of multiple bones while the lower jaw of mammals is a single bone. Fossil and developmental evidence indicate that the inner ear bones of mammals evolved from lower jawbones. This suggests that the inner ear bones of mammals are 1. an analogy 2. an exaptation 3. a living fossil 4. a transitional trait 5. a vestigial structurearrow_forwardIf you are a scientist studying the evolution of animals, what is the best approach you can use for analysis? analyzing behaviors of living animals with a common ancestry analyzing embryos and skeletons of animals of the same species analyzing DNA sequences and embryonic development analyzing the the fossilized remains of animals from different time periodsarrow_forwardTest Your Understanding 6.Which of the following is not characteristic of birds?
