Question
Chapter 13, Problem 9WIO
Summary Introduction
To determine:
The term determining the evolutionary divergence of the plants (plants of Chile and San Francisco) that happened long before this seed-dispersal method arose in each plant and to explain the answer.
Concept Introduction:
The two types of plants present in the two different geographical locations that have the same seed-dispersing method. The plants have diverged from each other before the generation of the seed-dispersing method.

Imagine that you wanted to know if speciation rate in plant groups is linked to whether the plants are pollinated by bees or hummingbirds. To do this, you identified 20 genera of angiosperms that contained species pollinated by both types of animals. There were substantially more species in the groups that were pollinated by bees. Which of the following conclusions are most consistent with your data?
A.
Hummingbirds promoted speciation less than did bees.
B.
Hummingbirds promoted speciation more than did bees.
C.
Each genus should first be split into two new genera.
D.
The rates of speciation are independent of pollinator type.

- Evaluate the following statements about seeds from two biology textbooks: I. The seed coat is an adaptation that protects the plant embryo from damage, water loss, and infection. II. Evolution has come up with a clever solution for protecting plant embryos: seed coats that prevent damage, water loss, and infection. Do these statements accurately represent the evolution of seeds? a) Yes, both statements are accurate. b) No, neither statement is accurate. c) Only the first statement is accurate.arrow_forwardOf the trees in the diagram below, which one of the four trees depicts a different evolutionary history than the others?

- Redraw and rearrange the branches of the tree below to make the most parsimonious(simplest) tree. A minus (“-“) next to a character indicates that that particular character isnot present in the taxa connected to that branch.arrow_forwardWhen building a phylogenetic tree, where do you place a number used to designate a change in character state?options: at a mark crossing the branch for the species that exhibits the new state at a node where two branches diverge at the end of a branch between the last species to exhibit the old state and the first to display the new statearrow_forwardThe “Progression Rule” of biogeography states that the oldest islands of an archipelago will host the oldest lineages of a radiation and the youngest islands will host the youngest lineages. The Hawaiian islands offer a number of examples of progression, one of which is depicted below. First, do Darwin’s Giant Daisies follow the Progression Rule? Second, describe a historical process of diversification and dispersal that might be responsible for the pattern you actually observe for Scalesia. This needn’t be completely precise—I don’t want every dispersal event documented!—just sufficient to capture the general process. (as a hint, he told me to consider speciation, extinction, and/or dispersal as the historical processes)arrow_forward
- Which statement portrays the concept of ontogeny in phylogenetics? option a.) scientist gathers physiological traits and genetic data about a group of endemic monkeys. option b.) Both chick and human embryos go through a stage where they have slits and arches in their necks that are identical to the gill slits and arches of fish. option c.) The progression of morphological forms observed in fossil record is consistent with inferences about the major branches of descent in the tree of life. option d.) Crocodiles have amniotic eggs while rodents and rabbits don't have.arrow_forwardA consortium of dairy and beef farmers has hired you to study the evolutionary origins of domestic cattle.

Identify the null hypothesis for this investigation? A. If the mean number of trichomes is greater in the second generation than in the parent population, then selection has occurred. B. There will be no difference between the mean number of trichomes in the second generation compared to the parent population. C. As a result of selection, the mean number of trichomes will be greater in the second generation. D. If plants with the most trichomes in the first generation are selected as parents, then the second generation will have more trichomes.arrow_forwardWhere in a phylogenetic tree would you expect to find the organism that had evolved most recently? a. at the base b. within the branches c. at the nodes d. at the branch tipsarrow_forward
