Human evolution shows that Homo Sapiens evolved physical features suitable to long-distance running. About two million years ago, the east African landscape entered a drying period, and many forested lands turned into grasslands or patchy open woodlands. These conditions would have favored our ancestors’ development of characteristics that could run after animals and scavenge prey

When does the story of Alice actually intersect with rabbits? In the case of evolutionary history — and a failed attempt at biological warfare in Australia.I can think of nothing that demonstrates the process of biological evolution more clearly than viruses.
