Scientists Have Sequenced Mammoth DNA That s Over a Million Years Old
17 FEBRUARY 2021
In a feat right at the limits of our scientific capabilities, an international team of geneticists has recovered and sequenced the oldest DNA to date.
From the teeth of three ancient mammoths that roamed Siberia between 700,000 and 1.2 million years ago, the researchers extracted extremely degraded DNA, and pieced it back together to reveal a previously unknown genetic mammoth lineage.
Previously, the oldest recovered DNA sample was from a horse bone found in the Yukon permafrost, dating back to between 560,000 and 780,000 years ago. This DNA is incredibly old, said evolutionary geneticist Love Dalén of the Centre for Palaeogenetics in Sweden. The samples are a thousand times older than Viking remains, and even pre-date the existence of humans and Neanderthals.
Sixty-one years ago this month, four North Carolina A&T first-year students walked through downtown Greensboro and “sat-in” at the Woolworth s whites–only lunch counter and asked to be served. The students refused to leave even after they were denied service and stayed until the store closed. Behind the counter, 23-year-old Charles Bess was working at the restaurant as a busboy during the sit-ins. Bess is now 83 years old but still reflects on what happened in Woolworth s when he was a young man, and what he believes still needs to happen today. Every time when a waitress would tell them we don t serve colored people here, they ignored it and kept on sitting and asking for coffee, Bess recalled. I never heard them asking for nothing else but coffee. Everyone was looking at each other wondering what was happening. I was standing close by and I wondered what was going on? Bess was proud of what unfolded that day. Across the nation, there is another new generation of yo
