Geneticist: studies suggest that the gene FOXP2, present in humans and many other species, is involved in vocal abilities. The chimpanzee version of FOXP2 differs more from the human version than from the mouse version, even though chimpanzees are far more genetically similar to humans than to mice. This strongly suggests that the differences between the human and chimpanzee versions of FOXP2 account for the development of human language.
Which of the following, if true, would most weaken the geneticist's argument?
A. The chimpanzee versions of the great majority of genes other than FOXP2 are more similar to the human versions than to the mouse versions.
B. The chimpanzee version of FOXP2 differs substantially from the versions in many species with no linguistic ability.
C. Some humans with rare versions of FOXP2 have impaired linguistic abilities
D. The human version of several other genes know to be involved in vocal abilities are as different from the versions in chimpanzees as is FQXP2.
E. In mice, as in humans, FOXP2 is known to be involved in several traits in addition to vocal abilities.

Premise 1 : studies suggest that the gene FOXP2, present in humans and many other species, is involved in vocal abilities.
Therefore, FOXP2 -> Vocal Abilities
Premise 2 : The chimpanzee version of FOXP2 differs more from the human version than from the mouse version, even though chimpanzees are far more genetically similar to humans than to mice.
Therefore, Chimpanzee version of FOXP2 closer to Mice than to Humans.
MiceFGene--ChimpFGene-------------HumanFGene
Conclusion: differences between the human and chimpanzee versions of FOXP2 account for the development of human language.
To weaken, we need to provide evidence that it is NOT JUST this gene but other Gene responsible, or that This GENE is not exclusively responsible.
Answer Choice D provides this clearly : The human version of several other genes know to be involved in vocal abilities are as different from the versions in chimpanzees as is FQXP2.
This answer choice mentions that OTHER genes known to be involved in vocal abilities are also different. Which could mean that maybe the other genes are the reason and not this one.
Therefore, FOXP2 -> Vocal Abilities
