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 <em>reproductively isolated</em> also.

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

Answer:The Answer Is C

Explanation:

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.

Why is it beneficial for the sex cells made at the end of meiosis to be DIFFERENT from each other?
Anestetic [448]

Answer:

if sex cells were identical, there won't be genetics variations and we will just all be identical to our parents. genetic variation allows us to better adapt and survive

La Rafflesia arnoldii es una planta tropical con una enorme flor rojo-sangre, que emite calor y despide olor a carne descompuest
Bingel [31]

Answer:

Rafflesia arnoldii is a tropical plant with a huge blood-red flower, which emits heat and emits the smell of decomposed meat. What use are these adaptations to this plant

Explanation:

The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.

Its possible Endothermy characteristic  is for mimicry Its releases  heat to attract  the pollinators- blowflies.The endothermic mechanism  is well pronounced during flora development: which further buttress the fact that this  is related to pollination to attract blowflies, and not to thermoregulation.
