Evidence has been found that shows that primate ancestors developed the ability to see color. previously, like most mammals, they could only see shapes using light and shadow. this evolutionary development was retained over millions of years as early primates evolved into modern primates, including humans. what is the best reason why this characteristic was incorporated into future hominid lineages rather than lost? this trait allowed early primates to see at night, when they hunted small animals for food. this trait enabled early primates to tell red and yellow fruits apart from green foliage. this trait allowed early primates to see movement to them evade predators. this trait enabled early primates to find shapes of fruits and insects in the tree canopy shadows.

The correct answer is the second option.

Explanation:

The character or the trait that is beneficial tends to hold or incorporated in the particular gene holder and if it is harmful than it leads to an inability to survive and lost the character in the particular gene holder. It is the process known as evolution.

The ability to see the color from just seeing shapes and light is beneficial for the hominids as it helps them to recognize the red and yellow fruits and distinguish them from green foliage. Other options are not related to the beneficial characters of the ability to see color.

Thus, the correct answer is option 2).

they are known to reach a speed of 21 miles per hour

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
