Cancer stem cells and the guardian of the genome

The p53 oncosuppressor gene, known as the "guardian of the genome," not only prevents cancer-causing mutations, but also prevents cancer cells from transitioning to a more aggressive state, close to the state of stem cells.

We are not only a little Neanderthals, but also a little Denisovans

Melanesians inhabiting the islands to the northeast of Australia received 4-6% of their genes from Denisovans. If we consider that the Neanderthals also left a trace in the genomes of modern humans, the total contribution of the "cousins" will be about 8%.
