Some 200 million years ago, in the southern part of the supercontinent Gondwana - which, today, is southern Africa - a huge carnivorous dinosaur roamed the landscape alongside smaller species. Fossil footprints have provided the first evidence of this gigantic beast’s existence. Lara Sciscio explains what led to this remarkable discovery.
A tremendous fossil record has cemented the theory that humans originated out of Africa. But every so often, research is published which claims to re-root human evolution in ancient Europe. Julien Benoit unpacks the problems with such research - and discusses its importance in aiding our quest for scientific truth.

Recent research suggests that humankind's origins lay outside of Africa. This is the nature of science: a paradigm that cannot be questioned on a regular basis becomes a dogma.
