Giant Hippos Invade England!
For me this is one of the most powerful pieces of evidence, in that it causes people to think:
Once upon a time, and not too long ago, hippopotami waded English rivers.
Hippos are from Africa, and African weather reaches the United Kingdom only a couple of times per year….
Pretty much there are only two valid reasons for hippos living historically in the British Isles:
1) Climate was much warmer
2) Hippos adjusted to cold weather for a while….
According to the Daily Mail:
1.8 million years ago, giant hippos were a common sight across Europe – even making it to the Norfolk Broads.
