Life is hard for Homo erectus, whose biggest challenge is to find enough food. At some point, one thing becomes very clear: It's better to hunt as a team!

In this episode of our journey through time, we meet the Neanderthals, who roamed the European continent for around 65,000 years before disappearing almost without a trace. They lived as clans of hunter-gatherers, and knew how to make tools and fire.

The Neanderthals discover that tools can be made from stones, new hunting methods are discovered, and the many different clans try to resolve disputes through negotiation.

The banished hunter finds a mate and is accepted into his new family as an equal. But there is someone who does not like that at all...

The Neaderthals discover that fire makes meat taste better than ever! As time goes on, they also refine their hunting techniques and even work out how to lay rather sophisticated traps.

The climate is getting colder, the animals are disappearing, and the Neanderthals are gradually running out of food. Times are tough, and the Neanderthals are being forced to do whatever they can to survive.

The cold weather and a shortage of food eventually drove the Neanderthals to extinction, clearing the stage for Cro-Magnons, our direct ancestors. But you'll have to wait for the next episode to find out more about that!

The European Fountain Society, with its seat in Karlruhe in southwestern Germany, is committed to the preservation and care of historical fountains and emphasizes the importance of water for man and culture.

We don't know exactly how and when life began on Earth, but the answer probably lies in the depths of the ocean: It is here that the first unicellular organisms evolved.

How do coral reefs form, and what role do they play for underwater creatures such as fish? In this video, you can see some fascinating life forms and how they interact with one another.

Brilliantly colorful parrot fish and two-bar sea bream are among the fish featured in this segment. Sea cucumbers, the vacuum cleaners of all the Earth's oceans, also make an appearance.

Different types of fish have very different tactics when it comes to survival in the coral reef, including camouflage, safety in numbers, and hiding in plain sight.

In this segment, we get to see some of the oldest inhabitants of the ocean and learn about how they have adapted to life under water.

In this video, we learn all about humpback whales. They might not be the largest whales, but they are extremely agile and graceful — and very musical as well!

We continue following the humpback whales, learning about their migration patterns and how they raise their young. We also meet Californian sea lions, which, despite their heft, are very agile and adept — and also very peaceful.
