When the Grand Canyon was forming, a population of squirrels were separated into two groups. The north side of the canyon is at a higher elevation and experiences more rainfall than the south side of the canyon. The two squirrel species you see here had a common ancestor, but over time, have evolved into two different species. How did natural selection lead to different species?

A) Because the squirrels were separated by the canyon, they were no longer able to reproduce and thus, became different species.
B) When the squirrels were separated, some of them acquired traits better suited for their new environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.
C) When the squirrels were separated, there was variation within each group. Some had traits that made them better suited for their home environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.
D) When the squirrels were separated, new mutations introduced variation within each group. Squirrels on each side of the canyon had different mutations. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.

Natural selection lead to different species when the squirrels were separated, some of them acquired traits better suited for their new environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.

Explanation:

The speciation in the squirrels due to the barrier in canyon occurred due to this. Such speciation is called allopatric speciation.

Speciation leads to formation of new species from the existing species due to change in their habitat or physical structure.

The squirrels on the two different side of canyon adapted to the habitat they are in. Their reproductive cycles, habitat and adaptation mode has become different due to the change in environment.

The species of squirrels became two as they reproduce and passed on the traits for survival in the environment which they had adapted.

The squirrels have become reproductively isolated also.

Genetic divergence takes place due to natural selection as squirrels arenow two different species.

slitherio is the original. its the best friend of all middle schoolers. the man you can count any time you have some free time. slitherio is the guy you hang with while you're in the computer lab suppose to be doing "research or whatever". slitherio isn't just a game but a friend.

wormaxio is just a fake trying to squeeze its way into the friend group. trying to pretend its cool and your best pal but how long has it really been there for you, really. it only wants you as friend to boost its social status. wormaxio is just annoying fake pleb. no offense

you and have a wonderful day

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
