SCIENCE, TECHNOLOGY, AND SOCIETY
In the United States, the rare red wolf (Canis lupus) has been known to hybridize with coyotes (Canis latrans), which are much more numerous. Although red wolves and coyotes differ in terms of morphology, DNA, and behavior, genetic evidence suggests that living red wolf individuals are actually hybrids. Red wolves are designated as an endangered species and hence receive legal protection under the Endangered Species Act. Some people think that their endangered status should be withdrawn because the remaining red wolves are hybrids, not members of a “pure” species. Do you agree? Why or why not?

Evolution in Humans
1) explain what evolutionary mechanisms are involved in creating variation in populations
2) define homology and analogy and discuss examples of each
The biological species concept is based on the assumption that species are reproductively isolated and do not share genes. And yet a number of organisms that are considered different species hybridize (mate and exchange genes). Hybridization between different species is more common in plants than in animals. Propose some possible reasons for this difference.
Which of these is an example of a key innovation?
A caterpillar of a butterfly species provides honey to an ant colony in order to receive protection and care.
A founding population of honeycreepers evolves beaks capable of cracking the seed of a tree species in their new habitat.
A new flower color morph arises in a plant population, but an associated pollinator does not distinguish flowers by color.
Co-occurring diploid species of wheat and goatgrass hybridize to form a viable tetraploid offspring that can no longer breed with its parents.

- According to the French naturalist Comte de Buffon (George Louis Leclerc), since the lion (Panthera leo), the tiger (Panthera tigris), and the leopard (Panthera pardus) are usually unable to produce fertile hybrids when cross-mated, we should classify: the lion and the tiger as members of the same species, but the leopard as a separate species the tiger, the leopard, and the lion as members of the same species the leopard and the lion as members of the same species, but the tiger as a separate species D. the lion, the tiger, and the leopard as three different species the tiger and the leopard as members of the same species, but the lion as a separate speciesarrow_forwardPlease help me and explainarrow_forwardPlease Help mearrow_forward

- A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring. Evolution is an important mechanism in the formation of new species. The evolution of a new species requires several components including all, BUT A) Evolution of a new species requires a long time. B) Evolution of a new species requires the need for a genetic change. C) Evolution of a new species requires a separation that prevents interbreeding. D) Evolution of a new species requires mutations that produce new genetic traits. not graded use photoarrow_forwardRama the cama, a llama-camel hybrid, was born in 1998. The idea was to breed an animal that has the camel's strength and endurance, and the llama's gentle disposition. However, instead of being large, strong, and sweet, Rama is smaller than expected and has a camel's short temper. The breeders plan to mate him with Kamilah, a female cama. What potential problems with this mating should the breeders anticipate?arrow_forwardInterspecific hybrids, if they survive, are (a) always sterile (b) always fertile (c) usually sterile (d) usually fertile (e) never sterilearrow_forward
