    Experts studied families with severe auto-immune or inflammatory conditions
    They found a gene variant that boosts the immune system response to disease
    The same gene is found in fossil Denisovans from more than 50,000 years ago
    This is the first gene from an extinct human species found to effect us today

Some modern humans have boosted immune systems thanks to a gene variant passed down from our ancient human relatives the Denisovans.

The variant — found today in people with indigenous Australian, Melanesian, Maori or Polynesian ancestry — makes the bearer more resistant to certain diseases.

A variant, once called a mutation, is a different form of a particular gene. Their effects can be positive, negative or benign.

This is the first time a single DNA sequence variant from an extinct human species has been shown to effect the activity of the modern human immune system. ...
