" important in responding to DNA damage"

Science University of Liverpool researchers have discovered the tree of life. Or rather the part of the genome in some animals like tortoises which explains why they have such long lives and could be utilised in the future to slow our ageing process:
"The team looked at the genome of more than 30 mammalian species to identify proteins that evolve in connection with the longevity of a species. They found that a protein, important in responding to DNA damage, evolves and mutates in a non-random way in species that are longer-lived, suggesting that it is changing for a specific purpose. They found a similar pattern in proteins associated with metabolism, cholesterol and pathways involved in the recycling of proteins."
Who wants to live forever? Well ...
