identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution
nignag [31]

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

What a vestigial structure? How does it support evolution?
atroni [7]
A vestigial structure is a structure that kind-of just "hangs out" in our bodies. We don't really need it, yet it is there. So, why is it there??? We probably needed it, for example, when we needed to digest plants. (Appendix) Some say that the appendix was used for digesting plants and berries, but it is really just speculation. We "evolved" to not need the appendix. 
Here are some other vestigial examples: wisdom teeth, tail bone, pelvic bone in a snake, and wings on a flightless bird. 
I hope this helped, if it did not let me know!!
