A decision by South Africa’s government to include more than 30 wild species—including rhinos, lions, and cheetahs—on a list of animals that can be improved by breeding and genetic research could cause considerable damage to their genetic diversity, scientists warn today in the South African Journal of Science.

Researchers find at least 4,184 of the endangered big cats have been since 2009Researchers trawled through 60,000 online adverts over the past decade to understand the extent of the trade.
