Hello, I was searching something about DNA and I found this good article. Over a century ago, the Cheddar man was unearthed in Gough's cave in Somerset. Back then researchers didn't have the technology to determine the eye and skin colour of the man but with the advancements in genetic research they found out he was dark skinned with blue eyes.

Thank you iNow. What about taking the worst scenario - no changing at all. How much do you estimate we could have a huge problem? Take a look at this article: http://www.evolving-science.com/environment-pollution/camera-can-see-global-warming-gases-they-appear-0075 Do you think we should be scared about future?

Greetings, I am trying to understand how serious is current situation of pollution on the planet? How long should it stand until everything collapse? I know it is hard to answer this question, but someone more knowledgeable than me should be able to say something more about this topic. Reasons and consequences preferable!
