Chapter 38, Problem 17TYK
Summary Introduction
To review:
Natural selection favors the evolution of additional tissue types and organ systems in larger organisms.
Introduction:
Natural selection is the process governed by nature where nature selects the beneficial traits and eliminates the harmful ones. Evolution is a developmental process, where there is a development of new trait or a new organism, which is accomplished by the change in inherited characters, which leads to the development of a new species.

Segmentation
Can be fused into specialized functional regions
Is seen in insects, worms, and their relatives
Is important in the evolution of increasing organismal disparity
Is seen in the Cnidaria (jellyfish and friends)
Is seen in vertebrates (animals with backbones, like you)
One of the earliest experimental embryology experiments was conducted by Wilhelm Roux, who used a hot needle to kill one of the cells in an amphibian embryo at the two-cell stage. In the experiment, the remaining living cell formed only half of an embryo. However, later vertebrate experiments showed that by completely separating cells in early embryos, each can make complete individuals. What could explain the discrepancy in these experiments?
You have seen many examples of how form fits function at all levels of the biological hierarchy. However, we can imagine forms that would function better than some forms actually found in nature. For example, if the wings of a bird were not formed from its forelimbs, such a hypothetical bird could fly yet also hold objects with its forelimbs. Describe the concept of “evolution as tinkering” to explain why there are limits to the functionality of forms in nature.

- Can you suggest why, during the evolutionary history of animals, there has been a tendency for maximum body size to increase? Do you think it inevitable that complexity should increase along with body size? Why or why not?arrow_forwardHow can embryos help scientists understand evolution? 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_forwardThe word invertebrate is so broad that it describes 95 percent of all living animal species. Do you think the term invertebrate is too broad to be useful to scientists? Give reasons to support your answer.arrow_forward
- Scientists believe that animals have a common ancestor because a. all animal appendages have been modified into limbs. b. all animal genes are very similar. c. all animals are autotrophs. d. all animals share unique features of the junctions between cells.arrow_forwardQuestion 4 Which of the following is not a statement of von Baer's laws? Less general characters develop from the more general, until finally the most specialized appear. The general features of a large group of animals appear earlier in development than do the specialized features of a smaller group. C) All of the above are Statements of von Baer's laws. D The early embryo of a higher animal is never like a lower animal, but only like its early embryo. E) The embryo of a given species, instead of passing through the adult stages of lower animals, departs more and more from them.arrow_forwardThe evolution of different body plans in animals has led to a wide diversity of species. For example, in Cnidaria (which includes jellyfish and corals) we see a radically different body plan compared to insects or birds. What significant evolutionary development is exhibited by insects and birds that is not present in Cnidaria? The development of bilateral symmetry and cephalization. The development of radial symmetry. The development of a calcified exoskeleton. The development of tentacles for capturing prey.arrow_forward
- Most animals show derived characteristics (character states) that differentiate them from their common ancestor (ancestral character state). However, evolution can also move in reverse, involving the change of a derived character state back to an ancestral state. Provide two examples from invertebrates of such ‘reverse evolution’ from a derived state (specialized state) back to a more ancestral character state. Make sure to use examples provided in this class. Provide two examples from invertebrates of such ‘reverse evolution’ from a derived state (specialized state) back to a more ancestral character state. Make sure to use examples provided in this class.arrow_forwardWhich choice best describes a reasonable mechanism for animal structures becoming better suited over evolutionary time to specific functions? Animals that eat the most food become the most abundant. Animals that restrict their food intake will become less abundant. Animals with mutations that give rise to effective structures will become more abundant. Animals with parents that continually improve their offspring's structures will become more abundant. Animals with inventions that curtail reproduction will become more abundant.arrow_forward4 The diagram below represents a Lystrosaurus. Lystrosaurus was an herbivore that lived on land about 250 million years ago. Fossils of this dinosaur have been discovered on the widely separated continents of Africa and South America. Which statement best explains why Lystrosaurus fossils are found on these two continents? (1) This dinosaur could fly to distant locations. (2) Both continents were once joined together. (3) Predators transported the remains of this dinosaur between continents. (4) Glaciers transported the fossils to the two continents.arrow_forward
- Many cephalopods have a structure found inside of their head called the "pen". Because cephalopods have a "pen", evolutionary biologists have concluded; Cephalopods are evolving an endoskeleton The pen is the result of a random mutation in cephalopods The ancestor to the these cephalopods had a shell That cephalopods are evolving a shellarrow_forwardIllustrate the Evolution of man and briefly explain. (You can either draw it or paste a printed illustration)arrow_forwardConsider Lamarck’s idea in a hypothetical situation. For example, you decided that when you have children, you want them to be big ang strong. You decided to go to the gym every day for a year. You did all your exercise routines diligently and you were able to develop really bulky and toned muscles because you believed that your kids would inherit your big impressive muscles. Do you think this would work? Justify your answer using the concepts you have learned from Genetics, as well as Darwin’s concept of evolution.arrow_forward
