how the Sahara became a desert The Sahara isn't exactly the place where you would want to store your DNA for a few millennia and expect it to still be readable, so it was a bit of a sensation that researchers recently published the first genome-wide analysis of 7000-year-old DNA of humans who lived there, when it wasn't a desert yet. A good excuse to look a bit more closely at the "Green Sahara" and how it became the Sahara desert we know today. It also serves as a warning, as some places are at risk of desertification due to climate change. The resulting feature is out now: **Becoming a desert** Current Biology Volume 35, Issue 10, 19 May 2025, Pages R357-R359 Restricted access to full text and PDF download (will become open access one year after publication) Magic link for free access (first seven weeks only) See also my new Mastodon thread where I will highlight all this year's CB features. My mastodon posts are also mirrored on Bluesky (starting 22.2.2025), but for this purpose I have to post them again, outside of the thread. (I think threads only transfer if the first post was transferred, so once I start a new thread it should work.) Last year's thread is here . The Acacus Mountains in Southwest Libya, where archaeological excavations at sites such as the Takarkori Cave have revealed a rich fauna and human habitation during the African Humid Period.

The prevalence of dust leads to questions about the past 'Green Sahara.' What caused it? Users discussed the potential for similar conditions to reoccur, suggesting significant environmental shifts are possible. #GreenSahara 4/6

Ancient DNA from the Green Sahara reveals ancestral North African lineage - Nature Pastoralism spread through cultural diffusion into the Green Sahara, where an isolated, distinct North African ancestry persisted.

Our study analyzing the DNA of ~7ky-old Pastoralists from the "Green Sahara" is out! Who were these people, and how did herding spread into the region when the present-day desert was dotted with water bodies? 🧬🦴🏜️ (1/7)

The Fulani Enigma: Unraveling the Deep Genetic History of Africa’s Legendary Pastoralists New research traces the origins of the Fulani to the Green Sahara, reshaping our understanding of migration, culture, and ancestry in Africa

The Fulani’s genetic origins trace back to the Green Sahara, blending African and Eurasian ancestry. This study reshapes our understanding of migration and diversity in African history.

Record of past floods of the Nile during the wetter North African Humid Period (7,500-9,500 yrs ago). Top: thickness of flood layers with green (yellow) thicker (thinner) layers indicating stronger (weaker) floods and the median thickness in black. Intervals of stronger floods also have a larger variability. Bottom: wavelet analysis of the thickness record with strong and significant signals (yellow) showing a strong influence of El Niño Southern Oscillation on flood variability.

3. We used a #varved sediment core from offshore the Nile mouth to reconstruct past #Nile floods during the #GreenSahara -> we observe much stronger #floods AND a higher variability of floods @varveswg
