Chapter 19, Problem 3PDT
Summary Introduction
To suggest: Some hypothesis for the apparent conflict between insect diversification and co-evolution of vascular plants.
Introduction: Competitive displacement is the process in which increasing diversity of species one clade causes a decline in the corresponding clade of species. Incumbent replacement is characterized by the extinction of one clade of species which enables the corresponding clade of species in the process of diversification later in their life. The evidence given by Labandeira and Sepkoski with respect to insect diversification and evolution of vascular plants did not favor the hypothesis given by Ehrlich and Raven.

If we compare DNA sequences of related species pairs (human vs. gorilla and D. melanogaster vs. C. elegans), which species pair is likely to show the most adaptive differences with the related species? Is it the human-gorilla pair or the fruitfly-nematode worm pair? Justify your answer.
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?
A.
Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous.
B.
Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease.
C.
The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins.
D.
All prokaryotes and eukaryotes use DNA to carry their genetic information.
E.
Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to each other.

- Peter and Rosemary Grant of Princeton University have studied the ecology and evolution of finches on the Galapagos Islands since the early 1970s. They have shown that finches with large bills (as measured by bill depth; see Figure) can eat both small seeds and large seeds, but finches with small bills can only eat small seeds. In 1977, a severe drought on the island of Daphne Major reduced seed production by plants. After the birds consumed whatever small seeds they found, only large seeds were still available. The resulting food shortage killed a majority of the medium ground finches (Geospizafortis) on Daphne Major; their population plummeted from 751 in 1976 to just 90 in 1978. The Grants research also documented a change in the distributions of bill depths in the birds from 1976 to 1978, as illustrated in the graphs to the right. In light of what you now know about the relationship between bill size and food size for these birds, interpret the change illustrated in the graph.

Next to the species names are the tooth morphology of each species. For example, species A has prominent molar teeth, thus likely a herbivore. On the other hand, species C has prominent canine teeth, thus likely a carnivore. Which of the following statements is correct? The most recent common ancestor for species A to H is probably a carnivore. The most recent common ancestor for species A to H is probably a herbivore. It is impossible to tell what the main food source is for the most recent common ancestor of species A to H. For species C, D, E, F, G, there are four evolutionary events that lead to the evolution of canine tooth morphology. IF the common ancestor of species C, D, E, F, G is a carnivore, then the molar teeth for species D is a plesiomorphy.arrow_forward

Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? Question options: Skeletal structures that indicate the development of legs. An intermediate structure between lungs and gills. Teeth that are intermediate to the lobe-finned fishes and amphibians. A neck that is more flexible than lobe-finned fishes.arrow_forwardHomo is best characterized by _________________ a.bipedal locomotion, large brain and biocultural evolution. b. lsrge teeth, bipedal locomotion and large brain c. quadrupedal locomotion , sexual dimorphism, and biocultural evolution d. bipedal locomotion, large brain and monogamyarrow_forward

Explain in terms of different adaptive behaviors to maximise growth, survival & other traits that contributes to the fitness of the species in a highly variable coastal environment. *arrow_forwardOn the nineteenth-century notion of a “scale of nature,” living amphibians were considered remnants of archaic terrestrial vertebrates largely superseded by “higher” forms including birds and mammals. Nonetheless, amphibian species are often more abundant and of longer evolutionary duration than avian or mammalian species. In what ways are amphibians unusally well suited for evolutionary persistence?arrow_forwardIs this evolutionary conservation of the pecten structure evidence that natural selection might be maintaining the pecten in its present form in many bird species? Is this theory one that suggests the pecten has a significant adaptive function in birds? Do you believe that experiments might be useful in determining the adaptive function of the pecten if it indeed serves an adaptive function? Outline a simple experiment to see whether the presence of a pecten in the bird's eye is an adaptation.arrow_forward
- Ornithopods and ceratopsians are characterized by numerous instances of convergence. Which of the following is NOT an example of convergence in (at least some members of) these groups? Select one: a. Some members of both groups evolved dental batteries to help them grind food more effectively. b. Both had bipedal ancestors, but independently became large and (at least partially) quadrupedal. c. Both groups independently lost their lower front teeth. d. Both evolved elaborate ornamentation (crests, frills, etc.) on their heads.arrow_forwardWhat hypothesis did Alfred Russel Wallace make about the uniquebirds and mammals on either side of an imaginary line in the MalayArchipelago? How did the eventual explanation for Wallace’s linedemonstrate the predictive power of evolution?arrow_forwardAnole lizards can be found on many islands in the Caribbean that share similar environmental habitats. Anoles on the different islands share similar ecological morphotypes because of their similar habitats. Anoles on each island have evolved from a common ancestor into a variety of different species that occupy different ecological niches as shown below. Which of the following statements explains how the morphotypes found on one island, and shown in the figure, occurred as a result of speciation? Convergent evolution occurred, causing new species to evolve based on diverse new habitats. Phenotypic diversification occurred as a result of divergent evolution as the anoles adapted to new habitats. Natural selection occurred, so individual anoles with certain phenotypes can survive and reproduce only in a specific ecological niche. Reproductive isolation occurred as a result of habitat isolation since the anoles are unable to move into different ecological niches to breed.arrow_forward
