Question

Last week, researchers claimed that they have sequenced Big Foot DNA, which suggests that they are hybrids between an unknown hominid species and humans (See article in Huffington Post). Dr. Bang thinks that this is a well-directed hoax because he teaches biology and knows a few good arguments. Which is NOT a good argument? a. Humans cannot mate with other hominid species because of prezygotic mechanical isolation barriers b. According to the biological species concept, two different species cannot get reproductive offspring together c. There have been found no fossil material of Big Foot, and no skeletons. d. If there is a species like Big Foot, the breeding population must be really large, and this would lead to many more sightings than the sporadic vague reports today.
