Reconstructing the Prehistoric DNA of Neanderthals

Reconstructing the Prehistoric DNA of Neanderthals

jurassic park adventure packHave we taken a step closer to Jurassic Park? That’s what I thought when I first saw the headline announcing that “researchers may remake Neanderthal DNA.” Unfortunately (or fortunately?), my imagination has misled me once again.

The point of reconstructing a complete Neanderthal genome is to understand how they and modern humans diverged over 30,000 years ago. The plan would be to use DNA samples from more than one Neanderthal corpse. Being able to put together an accurate DNA sequence despite contamination and degradation caused by microorganisms is a technical achievement as well.

For more about the analysis of ancient DNA, read this excellent piece by Henry Nicholls in PLoS Biology: Ancient DNA Comes of Age.

In 1994, while Jurassic Park was still taking in millions of dollars at the box office, scientists claimed to have extracted and sequenced DNA from an 80-million-year-old dinosaur. When sceptical researchers took a look at the sequence, it turned out to be of human rather than dinosaur origin.

Oops. Guess I wasn’t the only one with Jurassic Park on the brain.

I am fascinated by Neanderthals. Do we know for sure how they died out? Did they live at the same time? Oh, okay, I’ll google it… ;)

So, we’re reconstructing the Neanderthals and are almost on the verge of cloning a mammoth

…what a party that’s going to be!

John Hawks, a paleoanthropologist at the University of Wisconsin–Madison, says that every genetic difference between a Neandertal and a living person is a potential candidate for a gene or drug therapy. That sounds interesting…
