Concept explainers
To design: A study to determine whether two groups of mice living on the opposite sides of the river belong to the same species.
Concept introduction: Maximum studies in biodiversity involve field studies than lab studies, as it includes studies involving habitat fragmentation, demographic changes, mortality, fecundity, and many more. Therefore, best results will be obtained only when those studies are done on field. When animal studies are conducted where more than two species are to be studied, their
To explain: Mice captured from one field study and taken to lab will affect the experimental design for the field study or not.
Concept introduction: Maximum studies in biodiversity involve field studies than lab studies, as it includes studies involving habitat fragmentation, demographic changes, mortality, fecundity, and many more. Therefore, best results will be obtained only when those studies are done on field. When animal studies are conducted where more than two species are to be studied, their phenotypic characters are taken for studies to differentiate species initially.

- Imagine that two completely unrelated species in very different families were accidentally given the same name. What kind of confusion would this cause? What if both were separately the subject of several scientific studies, and results were published in papers that did not mention the family name. Would it be possible to know which study concerned which species?arrow_forwardIn your own words, describe why the orange beetles survived in relationship to what you have learned about natural selection.arrow_forwardWhat is Sympatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate themarrow_forward
- Why is it so important to learn about the Piltdown Hoax? Do you think it demonstrates that scientists may lose their objectivity when they want data to fulfill their expectations and desires or does it demonstrate the self-corrective nature of science? Why were people so willing to believethat one of the oldest specimens was found in south England?arrow_forwardThis technology to recreate extinct species is called _________arrow_forwardHow would you design an experiment to determine whether two populations of snakes are distinct species according to the biological species concept? For which types of populations does the biological species concept not work as a way of determining how they are related?arrow_forward
- In one paragraph, using your own words, describe how natural selection led to polar bears evolving to have white fur.arrow_forwardGive typing answer with explanation and conclusion What is an example of the bottleneck effect that actually happened in Earth's past? Why is that event a bottleneck and how does this bottleneck affect the evolution of the species involved?arrow_forwardWhich condition is the basis for a species to be reproductively isolated from other members? a. It does not share its habitat with related species. b. It does not exist out of a single habitat. c. It does not exchange genetic information with other species. d. It does not undergo evolutionary changes for a significant period of time.arrow_forward
- Do you think it is important that all species be prevented from going extinct? Explain your reasoning. Also, there is a process called “de extinction” where scientist use DNA from an extinct species and genetically “recreate” that species. Do you think this is a good idea? Explain you reasoning.arrow_forwardWhat are two ways that scientist measure similarity between organismsarrow_forwardExplain how the stickleback fish in this Alaskan Lake illustrated the process of natural selection.
