Born under the sun - UV light and the origin of life

http://www.brightsurf.com/news/may_03/BMC_news_052903.html

Early evolution of life as we know it may have depended on DNA's ability to absorb UV light. This insight into the early moments of life on Earth comes from research published today in the journal BMC Evolutionary Biology.

We know so little about the origin of life and is why the issue of life on Mars is so important to settle. All the answers might be found there...
