Scientists have found disturbing trend of Sharks reproducing asexually in captivity. This behavior only occurs for species under severe threat in natural habitat. I am an avid nature lover hence I find this development to be serious threat to mankind.

If humans continue to wreck havoc to nature at this rate, we will see new mutant species evolving in nature. The food chain will be severely altered that direct impact on human population. I got the link to the study. This is legitimate study that isn't sponsor by CNN fellow members.
