Proteins are stronger than expected

The DNA of fossil bones and protein parts are very useful to complete evolutionary history. However, by not coinciding with the kinetics of decomposition of organic matter, researchers have always shown great escepticity with this type of finding.

However, fossilized DNA has been found. Without far, there is the story of the ghost who wanted to clone. Contradiction? Not according to Professor Matthew Collins of the University of Newcastle. Collins explains how proteins found in a dinosaur bone have been preserved for so long. It seems that the minerals found inside the bones act as preservatives with proteins and the molecules break down because they are not as predictable as kinetic theories.

Knowing that it is possible, they will look more passionately for the organic footprints of fossils, which can answer many questions about evolution.
