Organism of the Day: Wolverine
The wolverine, pronounced /ˈwʊlvәriːn/, Gulo gulo (Gulo is Latin for "glutton"), also referred to as glutton, carcajou, skunk bear, or quickhatch, is the largest landdwelling species of the family Mustelidae (weasels). It is a stocky and muscular carnivore, more closely resembling a small bear than other mustelids. The wolverine has a reputation for ferocity and strength out of proportion to its size, with the documented ability to kill prey many times larger than itself.
Anatomically, the wolverine is a stocky and muscular animal. With short legs, broad and rounded head, small eyes and short rounded ears, it resembles a bear more than other mustelids. Though its legs are short, its large, fivetoed paws and plantigrade posture facilitate movement through deep snow.
42 Chromosomes exist in a wolverine skin cell. How many are in an egg cell?

Mystery Question!
It was definitely not a science fiction movie. The animal in the laboratory was real. Besides having to forward looking eyes, it also had eyes on its knees and eyes on its hind legs. It even had eyes inthe back of it's head. Yet as strange as it looked, this animal was not a monster. It was simply a fruit fly with eyes in very strange places. These eyes looked like the fly's normal compound eyes, but a mouse gene transplanted into the fly's DNA had produced them. How could a mouse gene produce extra eyes in a fly?
As you read the chapter, look for clues to explain how a gene that normally controls the growth of eyes in mice could possibly cause a fly to grow extra eyes in unusual places. Then, solve the mystery.
Discuss with your neighbor for 1 minute.
