Secrets of the Longest-Living Mammal Revealed


Secrets of the Longest-Living Mammal Revealed

The genome of the bowhead whale was released this week by scientists who say that it may hold the key to longer and healthier lives for humans. The bowhead whale is the largest animal whose genome has been sequenced. It lives longer than any other mammal, with a lifespan of up to 200 years. Scientists studying its genome found significant differences in genes related to cell cycle, DNA repair, and aging process compared to other mammals. Although it has about 1,000 times as many cells as a human, its cells have a far more efficient anti-tumor response. More… Discuss

FOUNDER EFFECT (Hannibal Lecter)


Founder Effect

The founder effect is a form of genetic drift that occurs when a small group in a population splinters off and forms a new one. These founders can strongly affect the new colony’s genetic makeup far into the future, since their small gene pool may be unrepresentative of that of the population at large. Down the line, this can result in an increase in recessive traits, even maladaptive ones, like certain genetic diseases. What are some communities that have been impacted by the founder effect? More… Discuss
