You have seen many examples of how form fits function at all levels of the biological hierarchy. However, we can imagine forms that would function better than some forms actually found in nature. For example, if the wings of a bird were not formed from its forelimbs, such a hypothetical bird could fly yet also hold objects with its forelimbs. Describe the concept of “evolution as tinkering” to explain why there are limits to the functionality of forms in nature.
Vestigial structures have ________ in a modern organism.
minimal influence
minimal influence
key roles
key roles
no apparent function

For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs.

- Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________.

- A. Explain which force of evolution is seen here by a hybrid bird landing on an island that is not its home and breeding with the indigenous population. B. Explain which force of evolution randomly chooses an individual from a larger gene pool to form a new, smaller population with less genetic variety.arrow_forwardof this =rab or ditions ionary escen- se or 5. Describe two examples of vestigial structures that you can find among the Caminalcules. These are structures that have been reduced to the point that they are virtually useless. Ear muscles and the tail bones are examples of vestigial structures in our own species. Explain how vestigial structures provide clues about a species' evolutionary past. Illustrate your argument with vestigial structures found in humans or other real species.arrow_forwardMost animals show derived characteristics (character states) that differentiate them from their common ancestor (ancestral character state). However, evolution can also move in reverse, involving the change of a derived character state back to an ancestral state. Provide two examples from invertebrates of such ‘reverse evolution’ from a derived state (specialized state) back to a more ancestral character state. Make sure to use examples provided in this class.
