From humble beginnings to global dominance. Our earliest mammalian ancestors were little shrew-like rodents, struggling to survive in a world ruled by dinosaurs. Today, mammals fill a variety of niches. Rodents are still found around the world, but we also have large carnivores, enormous whales, flying bats and highly intelligent primates.
There are somewhere between 230 and 270 primate species in the world, over half of which are endangered due to human activity: habitat clearance for agriculture and expansion, hunting for bushmeat, the illegal pet trade.
In my own experiences observing and interacting with primates, I saw the same expressions of delight, frustration and compassion that we've all seen from our own friends and loved ones. These are beings closely linked to us by taxonomic proximity, emotional capacity and social complexity.
