Question

The diagram below shows horses in different periods of time on Earth. Based on the diagram, it can be concluded that horses have A) not always used their limbs for running. B) not shown any evolutionary changes over the years. C) evolved to help them survive in changing Earth conditions. D) evolved to reduce their running and walking speeds.

Answer 1

C, evolved to help them survive in changing earth conditions

Step-by-step explanation:

The speed of the horse itself has not changed, what the horse is doing here is to adapt to the changing conditions. This occurs through evolution(natural selection). It is hard for us to infer the changed in speed just from the given diagram, this D is wrong since horses have never had to reduce their running and walking speeds for any reason. A and B are wrong b/c evolutionary changes are obviously shown and horses have ran in a similar fashion for millions of years, as shown in the diagram as well. Therefore, answer C is correct. Have a great day!

Answer 2

B. not shown any evolutionary changes over the years
