Today, at the American Museum of Natural History in New York, a revolutionary discovery — one that will stand as a milestone for paleontologists and evolutionists everywhere — was announced. Scientists based at the University of Oslo have discovered “Ida,” also known as Darwinius masillae, a 47-million-year-old fossil that has been proclaimed the “missing link” in connecting human skeletal structure to early mammals.

Scientists found Ida in Messel Pit, Germany and soon found out that she is about twenty times older than most fossils related to human evolution. What makes Ida so special is that despite her classification as an early prosimian (lemurs), she has certain undeniable human characteristics such as forward facing eyes and even an opposable thumb.

This is an exciting and validating day for scientists everywhere. Broadcaster and naturalist Sir David Attenborough has said: “This little creature is going to show us our connection with all the rest of the mammals.”

Head on over to The Link for pictures, video and more information about Ida and the team of researchers behind her. Also don’t miss what’s up at the open source journal PLoS One to read about the scientists’ findings.

“What we call governments are vampire states, which suck the economic vitality out of the people.” — Economist George Ayittey

“I want to make Africans rich. If you make Africans rich, they’ll be less poor. That’s my development strategy.” — Private equity pioneer Idris Mohammed

“What we’re trying to do is create a family tree for everyone alive today.” — Anthropologist and geneticist Spencer Wells, who’s leading the Genographic Project, a landmark study tracing human origins to their roots in Africa

“There is no region of the world and no period in history that farmers have had to bear the burden of risk that African farmers bear today. But I’m not here to lament or wring my hands. I’m here to tell you that change is in the air.” — Economist Eleni Gabre-Madhin, who is founding the first commodities market for farmers in Ethiopia

“World progress needs a good dose of spontaneous human intelligence to realize that the answers to many of the questions we ask ourselves are just around the corner.” — Architect Issa Diabete, who draws inspiration from innovative, makeshift urban solutions found in Africa’s sprawling squatter cities

“I’m hopeful because nature is amazing resilient. Seemingly dead tree stumps — if you stop hacking them for firewood, in 10 years you can have a 30 ft tree.” — Primatologist and conservationist Jane Goodall

“I am a mathematician and I would like to stand on your roof.” — Mathematician Ron Eglash’s standard greeting to African families, when he was researching the intriguing fractal patterns observed in many villages across the continent

Ingenious solutions are being applied to tackle some of the toughest health and infrastructure problems. Businesses are being launched that can transform the lives of millions. New communication technologies allow ideas and information to spread, enabling markets — and governments — to be more efficient. The numbers suggest that real growth is on the way … A new Africa beckons.

Next week, we hold our first conference in Africa (also titled “Africa: The Next Chapter”) to learn all we can about the profound changes sweeping the continent. Thought leaders from across Africa will gather with counterparts from the west in hopes of building new and lasting collaborations. But the meeting in real time is only the beginning: It’s the conversations and connections that continue online which will have even deeper reverberations.

Though the talks from TEDGlobal won’t be online till midsummer, we’ve started the conversation off with several relevant talks from TEDs past, including Ngozi Okonjo-Iweala, the pioneering Nigerian Finance Minister, who captures the zeitgeist of the moment with a talk on rethinking the African economy. It dovetails nicely with Jacqueline Novogratz, who promotes a new approach to philanthropy, based on investment rather than traditional aid. Both those thoughts were echoed by Ashraf Ghani, former Finance Minister of Afghanistan, whose rousing talk on his country’s future resonates with this theme, despite geographical distance. And then there’s Bono, whose memorable 2005 TED Prize acceptance speech was the original inspiration for the conference (though many there may disagree with his approach).
