Scientists who resurrected a 50,000-year-old gene sequence have analyzed it to figure out how the world’s deadliest malaria parasite jumped from gorillas to humans - giving insight into the origins of one of human history’s biggest killers.
The researchers said their work also deepens understanding of a process known as zoonosis - when a pathogen that can infect animals acquires genetic changes enabling it to infect humans - as has been the case with diseases such as flu and Ebola.
