Where are all the east coast dinosaurs? Why don’t we find famous species like Triceratops in Central Park? Turns out, evolution and geology came together to make the east coast into an ancient lost world of weird dinosaurs.

After having solved the small matter of evolution by natural selection - becoming one of the most famous scientists in the world in the process - Charles Darwin turned his focus to a different personal obsession…

The story of the egg spans millions of years, from the first vertebrates that dared to venture onto land to today’s mammals, including the platypus, and of course birds. Like chickens? We’re here to tell you: The egg came first.

For decades, scientists believed dinosaurs were diurnal and tiny mammals were nocturnal. But as researchers have uncovered more mammalian fossils and studied the biology of different dinosaur species, they’ve found some surprising results.

In this video Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are...

Dinosaurs were social animals, moving in herds, hunting in packs, but could they dance?

Prehistoric teeth prove that hyenas once roamed the Arctic and the relationship between ancient crocodiles and climate is more complicated than we thought.

Paul Andersen describes genetic drift as a mechanism for evolutionary change. A population genetics simulator is used to show the importance of large population size in neutralizing random change. The near extinction of the northern...

Paul Andersen describes pieces of evidence that Charles Darwin used to support the idea of evolution and his process of natural selection. He begins with the following evidence use in the Origin of Species; artificial selection,...

In this video Paul Andersen explains in more detail the history of the Earth. He shows how the history of the Earth is written in the rocks that are built up over time. Fossils allow us to compare different rock layers relative to one...

The infamous "Surgeon's Photograph" of the Loch Ness Monster, taken in 1934, greatly boosted the legend's popularity. The photo made Nessie a cultural icon and international tourist attraction. Despite later information that proved the...

2 million years ago, two species of apeman had evolved different strategies to survive the African environment. When the landscape changed, which would continue on the path to becoming human, and why? Biology - Adaptation And Evolution -...

Homo ergaster had a huge brain and lived in complex social groups, but his evolution was stunted for a million years, until he discovered fire. Biology - Adaptation And Evolution - Learning Points. Homo ergaster evolved from homo habilis...

For thousands of years scientists have named and categorized the vast array of life on Earth. This series of videos highlights the major advances concerning the classification of life, more specifically focusing on current trends in...
