Young Wolf

by Abdulla » Sun Nov 15, 2009 4:45 pm
In 1977, a young wolf was observed entering a cave in pursuit of prey. Soon, other wolves started entering the cave, and over the next few seasons, this behavior became the norm for the entire wolf pack. Before 1977, no wolf had been seen entering or leaving the cave, and no signs of wolves were found in the cave. By 2004, the entire pack was spending most of its winters in or near the cave. Therefore, these wolves are capable of adopting and passing on new behaviors, and are not merely bound by their genetics.

The argument above is based on which of the following assumptions?


A) Genetic mutations in wolves can occur in a fairly short timespan such as a few decades.
B) New behaviors that emerge in wolf populations over the course of a couple of decades are not necessarily genetically predetermined.
C) Only after certain patterns of behavior become the norm for a given animal population can it be inferred that a genetic mutation has occurred in that group.
D) The social actions of wolves are fully independent of their genetics.
E) The wolves' new pattern of behavior will continue for several generations to come.

IMO:B

negate B -
New behaviors that emerge in wolf populations over the course of a couple of decades are not necessarily genetically predetermined

New behaviors that emerge in wolf populations... are ....genetically predetermined.

conclusion is no more valid. Hence, B.
