Question

Which species is most likely to share the greatest percentage of DNA with humans?
A) blue jay
B) beaver
C) leopard frog
D) dragonfly

Accepted Answer

The beaver (Castor canadensis) is a mammal and belongs to the same class (Mammalia) as humans. Being a mammal, they would possess more similar genetic material to humans than species in other classes such as the blue jay (Aves), leopard frog (Amphibia), or dragonfly (Insecta). In fact, according to recent studies, beavers share approximately 84% of their DNA with humans.
