As bоttlenecks gо, they dоn't get much nаrrower: bаsed on а genetic study, scientists found that Florida panthers, nearly wiped out in the early 20th century, dropped to a population size of as little as six animals. Scientists compared DNA samples taken from museum specimens from the 19th century with samples from the 1980s. They found that the late 20th century cats had only a third of the genetic diversity of their 19th century ancestors. The bottleneck caused widespread health defects in the wild cats, including undescended testicles and poor sperm quality. A "genetic rescue" experiment was launched in Florida in 1995, when eight female pumas from Texas were introduced to the Florida panthers. The question is: which evolutionary mechanism is purposefully used in this "genetic rescue"?
