Textbook Question
Chapter 17, Problem 1MC
The biological species concept is difficult or impossible apply to
- a. asexually reproducing organisms.
- b. large organisms.
- c. rapidly evolving organisms.
- d. plants.
Expert Solution & Answer
Summary Introduction
Introduction:
Biological species concept involves interbreeding populations in the environment, which shows reproductive isolation from each other. Biological species do not involve exclusively asexual organism.
Answer to Problem 1MC
Correct answer:
The biological species concept is difficult to apply to asexually reproducing organism. Therefore, option (a). is correct.
Option (a). is given as “asexually reproducing organism”.
Explanation of Solution
Justify reason for the correct statement:
The biological species concept does not involve organism which reproduces asexually, as asexual reproduction does not provide species boundaries for sexual isolation.
Hence, option (a). is correct.
Justify reasons for the incorrect statements:
Option (b). is given as “large organism”.
Interbreeding does not occur in species which involves large organism and they are restricted to reproductive isolation. Hence, it is a wrong answer.
Option (c). is given as “rapidly evolving organism”.
In a species, identical population diverge and leads to the formation of new species by maintaining its reproductive isolation. Hence, it is a wrong answer.
Option (d). is given as “plants”.
Plants are sexually reproducing organism and they maintain their reproductive isolation. Hence, it is a wrong answer.
Hence, options (b), (c) and (d) are incorrect.
Conclusion
Biological species involves organisms of the same species which can interbreed with each other.

Which of the following claims of the biologist are true and which are false? 1. The BSC potentially would work for all multicellular organisms. 2.

- The biological species concept depends on the existence of barriers to reproduction. What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…arrow_forwardEvolution is the theory that species change over time. According to this theory, new species form from existing species through variation and natural selection. The evolutionary process is very slow and the transformation of one species into another requires thousands of years. Several evidences are used to prove evolution and somehow reconstruct how this process occur: 1.Fossil Records. 2.Homologous Body Structures. 3.Vestigial structures. 4.Similarity of embryo. 5.Geographical evidencearrow_forwardOf the following taxonomic categories which is the most inclusive (i.e. is the highest in hierarchy)?
