Jurassic Park: Why we're still struggling to realize it 30 years on

DNA yields th Hollywood tailed information, compared to other molecules, on how closely species are related.

DNA can sometimes survive in polar climates, because 1993 ezing temperatures slow down decay.

Scientists have yet to find evidence that actual DNA can survive for tens of millions of years.

This is paving the way for more rigorous studies of ancient molecules. In the future, these studies may challenge what we think we know about how long molecules can survive, and may even reshape our understanding of the evolution of life on Earth.
