Which hypothesis provides the best explanation as to why the Manchester Peppered Moth populations changed over time?
As the soot covered trees became more prevalent, lighter colored moths stood out and were eaten.
Before mountain building occurred, this area was underwater.
The herbivores with longer necks can reach the leaves, survive and reproduce. The herbivores, over time, have longer necks.
sedimentary
Coloration was a form of camouflage.
Group E
genetic mutation
In a population of fast-running cheetahs, some are born that run slower than most.
Consider the model (#!17) for natural selection. Describe a scenario that represents this model of natural selection.
