Published online Nov. It was led by Robyn Pickering, an isotope geochemist at the University of Cape Town, who began dating the cradle cave fossils 13 years ago as part of her doctoral research. We helped Robyn sort out some of the broader implications of this work for understanding how, when and why our early ancestors and close relatives evolved. The Cradle of Humankind is a World Heritage Site northwest of Johannesburg that includes complex fossil-bearing caves. Until now, it has proven difficult to precisely date these fossils and assess their evolutionary history, owing to the disordered nature of the collapsed cave sediments in which the remains were preserved. Pickering and colleagues instead analyzed the thick flowstones that surround the fossil-bearing sediments, which can be dated by measuring their trace radioactive isotopes. Flowstones, such as stalactites and stalagmites, form in caverns when flowing waters deposit dissolved minerals. The authors find that flowstones were deposited in six intervals between 3. These, they suggest, represent wetter periods, in which there was more water to deposit the flowstones and the caves were more likely to be closed off to incoming sediments and hominin remains, allowing flowstones to form uninterrupted, but leaving gaps in the fossil record.

An international team of researchers led by Oxford University has new dating evidence indicating when the earliest fully modern humans arrived in the Near East, the region known as the Middle East today. They have obtained the radiocarbon dates of marine shell beads found at Ksar Akil, a key archaeological site in Lebanon, which allowed them to calculate that the oldest human fossil from the same sequence of archaeological layers is 42, — 41, years old.
This is significant because the age of the earliest fossils, directly and indirectly dated, of modern humans found in Europe is roughly similar. This latest discovery throws up intriguing new possibilities about the routes taken by the earliest modern humans out of Africa, says the study published online by the journal PLOS ONE. The research team radiocarbon dated 20 marine shells from the top 15 metres of archaeological layers at Ksar Akil, north of Beirut.

After the stress of going through a divorce , it can be difficult to think about dating again. Everyone has their own timeline for when they might want to get out there. Even if you know your marriage is really, truly over, you still need to give yourself some time and space. Although it might be tempting to lick your wounds with positive attention from another, this distraction can actually inhibit you from the healing work that is necessary to move forward in a healthy way with someone in the future.
Dating requires a certain amount of vulnerability, tolerance of uncertainty, and willingness to feel a range of emotions in the hopes of making positive new connections and relationships. It is possible that your first relationship post-divorce might not be a rebound, but there’s a lot of “ifs” that go along with that. A ‘first’ relationship post-divorce can last, provided the person has learned about themselves and their part in the ending of their marriage.

But there I was, sitting on my sofa, worrying if I was, to quote indie pop band London Grammar, wasting my young years. It had been a difficult week, to say the least. I was sleep-deprived and my anxiety was running riot.
What I needed most right then and there was a quiet, restorative night of doing nothing. I was hiding under a blanket on my sofa when my phone started flashing like a lighthouse on the horizon. Four Hinge notifications appeared on my home screen in close succession. I had a new match named Jake. My eye scrolled downwards to see that Jake wasn’t wasting any time: He wanted to meet up. Right now. I really didn’t want to do that. It was 9 p. The last thing I wanted to do was leave the house for what felt like a booty call.
