Design an experiment lasting 100,000 years to test whether allopatric separation leads to speciation. What would your study organism be? Why? What would you measure, how often would you measure it, and what would you expect to find if the allopatric speciation hypothesis is correct?

Expert Solution & Answer

Summary Introduction

To design:

An experiment which lasts 100,000 years to test whether allopatric separation leads to speciation, and what would be the organism of study, and why that particular organism is chosen. Also, to determine how often experiment would be measured, and expectation related to finding if the allopatric speciation hypothesis is correct.

Introduction:

Speciation means the formation of a new species from the pre-existing ones. Allopatric speciation occurs when geographic isolation creates reproductive barrier among the individuals of the same population.

Explanation of Solution

Hypothesis: Allopatric speciation is correct.

Experimental animal: Drosophila, as it fulfills the conditions as an experimental animal, which must have a known genetic sequence and short lifespan of about 30 days.

Experiment: To test the hypothesis that the allopatric speciation is correct.

Method: Same species of Drosophila are collected from the same geographical environment, and divided into three groups: two experimental groups and one control group.

The two experiment groups are isolated in two different geographical areas, whereas the control group is kept in the same geographical environment.

Measure: The experiment is screened every 30 days in every new generation in order to obtain data about the traits gained and the traits eliminated in all three groups.

Analysis: Along the generations, each experimental group emerged with different characters and accumulated changes in genetic composition in comparison to the control group.

Finding: After 100, 000 years, along with the generations, the accumulated changes in both experimental groups lead to speciation.

Conclusion

Drosophila would be the study organism for allopatric speciation, as it has a very short lifespan and its genetic composition is known. The result of the experiment is measured after every generation.

Students have asked these similar questions

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…

Compare the forms of speciation that are slow to those that occur more rapidly. Make a list of the slow and fast forms. With regard to mechanisms of genetic change, what features do slow and rapid speciation have in common? What features are different?

which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.
