The embryonic development of animals suggests an order of relation between humans and other animals; some animals being more clo
sely related to humans than the others. Which of these options arranges the animals in a DESCENDING order of closeness of relation with humans? A) I, III, II
B) II, III, I
C) III, II, I
D) II, I, III
As you can see in the picture presented below, the 3rd image of the embryonic development resembles the human embryonic development very much, which may indicate the evolutionary closeness of these animals with humans. The second an third images show various differences in the embryonic development and therefore also show a smaller degree of evolutionary closeness with humans
The theory is most likely A) Valid. If a group of authorized scientists agreed on the theory, it would be valid. It would most likely be unreliable if it was only one scientist working alone and biased. If you don't have a group of scientists, the theory most likely won't be true because it hasn't been tested many times.
