MIT biologists decipher 3 billion year old genetic 'fossil'

• Terrence Aym
Biologists at the Massachusetts Institute of Technology have successful deciphered a 3-billion year old genetic fossil and found that an ancient surge of life on Earth was related to the sun. For some time it's been known that a surprising upsurge of life happened early in Earth's development. To test the theory that the sun may have played a major role Eric Alm and Lawrence David, researchers on the project created what they call a “genomic fossil”--a mathematical model based on the 100 genes that are critical to all life today. Using the model they walked it backwards in time to determine how the genes must have evolved to become their present-day form.
