1. The exercise we performed used the example of geographical separation to isolate the populations. However, populations can become isolated even when they are living side by side. List four things that could change in a population that would result in reproductive isolation of two populations despite the absence of a geographical barrier. Explain your reasoning for each. (1 pt.) 2. The wing of a bird, a bat, and a honeybee are all very different structurally yet they achieve the same goal: flight. Explain how each of these three unrelated organisms could have developed such similar but different traits. (1 pt.)

Structural barriers refer to physical differences in anatomy that prevent successful mating, behavioral barriers involve differences in mating behaviors or signals, and temporal barriers occur when populations breed at different times. Show more…

In order for a species to be reproductively isolated there must be some isolating mechanisms in place. An example of a reproductive isolating mechanism is: (check all that apply) Group of answer choices Different mating calls Different mating seasons Geographical barrier

1.) When a population is split by a physical barrier such as a mountain range, interrupting gene flow: a) they can accumulate genetic differences while separated. b) they will evolve wings to fly over the mountains. c) they will become new species. d) they can evolve into new species over time. 2.) In allopatric speciation: a) populations do not exchange genetic information. b) populations can become reproductively isolated. c) populations are separated by some physical barrier. d) new species arise from within a population with no physical barriers to gene flow.

Suppose that females of one population of strawberry poison dart frogs (Dendrobates pumilio) prefer to mate with males that are orange-red in color. In a different population, females prefer males with yellow skin. Explain how such differences could arise and how they could affect the evolution of reproductive isolation in allopatric versus sympatric populations.
