Researchers have partly sequenced the genome of the second case of the new coronavirus that has emerged in the Middle East (the patient currently in London), and confirmed that it is the same virus as that infecting the man who died in July. They have also confirmed that it is not the came as the virus that causes SARS.

Analysis of a Siberian cave girl’s genome links ancient and modern humans, and shows that she had brown hair, eyes and skin.  The DNA comes from a fragment of finger bone found in the Denisova Cave in the Altai Mountains in East Central Asia. The bone is thought to be 30,000 to 50,000 years old.

Frogs that are more athletic have genes that change faster. Researchers put frogs through fitness tests and then sequenced their genomes, and found that the fittest poison frogs had more changes to their genes. It’s not quite clear why – it might be because of the extra oxygen in the blood after exercise.

Researchers have sequenced the genome of Otzi the Iceman, who froze in an Italian glacier 5300 years ago. According to this, he probably had brown eyes, belonged to blood group O and was lactose intolerant.

The chicken – well, the red jungle fowl, the forerunner of the domestic chicken – was the first bird to have its genome sequenced, back in 2004.

According to members of the International Chicken Genome Sequencing Consortium, the chicken genome contains less DNA than the human genome, but around the same number of genes.
