has the closest evolutionary relationship with humans?

Humans and chickens - 3 different DNA molecules
Humans and horses - 1 different DNA molecule
Humans and tuna - 5 different DNA molecules
Humans and frogs - 4 different DNA molecules

Select one:

Answer:

horse

Step-by-step explanation:

Based on this evidence, the animal with the closest evolutionary relationship to humans is the horse. Molecular evidence for evolution is based on the study of the genetic makeup of different species to understand their evolutionary relationships. In this case, the scientist is comparing the DNA sequences of different animals and observing the number of differences between them. Since horses have only one different DNA molecule compared to humans, this suggests that they are closely related and likely evolved from a common ancestor, making them the closest evolutionary relative to humans among the animals listed.
