How did Camels evolve?
What are Paracamelus?

Paracamelus is an extinct genus of animals, known only from fossils, that  are in the family Camelidae (camels, llamas, alpacas etc). By all accounts some of them were very large beasts!


As for how camels evolve... well that's a slightly vague question I'm afraid so hard to answer other than in vague terms (i.e. from camel-like ancestors as a consequence of mutation, natural selection and genetic drift). However, there are quite a few recent papers looking at more specific aspects of camel evolution if you look around. Here's one from a couple of years ago that may be of interest
