>>I'm supposed to live in a city - it's densely populated with terraced houses in streets and an animal has to cross roads to get to the park. A few years ago a fox (could be the same friendly-neighbourhood) in our street calmly stood and let me take close-up flash photos of it. Is it that these urban animals are evolving to be less scared of us predators?

>Fangs bared! That's learning, not evolution. :)

No kidding - I saw it (next doors dog was barking wildly at it too), ran in the house to get some food for it - by the time I came out (a few minutes) it had trotted up the street, so I followed it and dropped a trail of ham to entice it back. It followed me but, strangely, did not pick up any ham (perhaps it was kosher?). I told it to wait and ran inside to get my camera (another few minutes), then it just ambled about while I took photos. I thought the flash would scare it but it didn't even flinch.

Could be evolution in that the foxes that have become less afraid of humans get to get the richest garbage picking, plus whatever benevolent humans put out for them. They get fat and reproduce, standing less chance of being killed as vermin, whereas those in rural areas get killed off by farmers and hunts.

Evo can happen very quickly. In parts of Africa we have predominantly tuskless elephants, cos the "tuskers" have all been poached, so the only repro going on is of the tuskless ellies.
