Can science explain the origin of life? A full scientific explanation for the origin of life does not currently exist, but research groups around the globe are tackling the mystery. Here we'll take a look at a few of their discoveries. 

Darwin's theory of biological evolution tells us that all life on Earth may have originated from a single, relatively simple reproducing creature, living in the distant past. This idea is based on many observations one of which is that when living things reproduce, children are often born with random new traits. 

Those with negative new traits are less likely to survive and reproduce. Those with positive new traits are more likely to survive and pass those traits on to their children. Over multiple generations, positive traits build up allowing relatively simple life forms to evolve into complex life forms and even split into multiple different species. 

A careful look at the fossil record overwhelmingly confirms Darwin's theory - life forms get simpler and simpler as we go back in time. The record suggests that all life on Earth emerged from primitive cellular colonies which first appeared roughly three and a half billion years ago.

Those with negative new traits are less likely to survive and reproduce. Those with positive new traits are more likely to survive and pass those traits on to their children. Over multiple generations.

The bugs mum had different babies one was with browne legs and whiten legs the whiten bug died the one with browne legs survived because the brown bug was camoflague with the tree.

So the brown bag made more babies and they all got bigger and one was bigger and one seller the seller bug died because it looked like food.
