Scientists show that DNA can last for up to 50,000 years in Africa - much longer than previously thought
Researchers have successfully extracted DNA from a 50,000-year-old antelope tooth in South Africa, setting a new record for ancient DNA preservation in sub-Saharan Africa. This discovery challenges previous assumptions that the region's hot climate prevents long-term genetic material survival.
Why it matters
This breakthrough opens new possibilities for studying the evolutionary history of human ancestors and extinct species in regions previously thought to be unsuitable for DNA preservation.
Researchers extracted DNA from long-dead animals that lived in South Africa during the last ice age, revealing that genetic material lasts longer in hot climates than was previously thought.
