Question

After the beginning of the Industrial Revolution, the black moth population was nearly 98% of all moths in this region. This was a turnaround of nearly 100%.

Think about long-neck and short-neck giraffes. What would happen over time if all the shrubs and ower leaves on the trees disappeared?

Answer 1

Without the shrubs and lower leaves on the trees, the long-neck giraffes would have an advantage over the short-neck giraffes. The long-neck giraffes would be able to reach the higher leaves on the trees, while the short-neck giraffes would not. Over time, the population of long-neck giraffes would increase, while the population of short-neck giraffes would decrease.
