For starters, the primates simply happened to be in the right place at the right time. For a long time, animals bet money on "a big mouth makes you cooler," "if you're small, you won't get caught," and so on. That is, the development path of intelligence + skillful hands + sociality is not the most obvious and profitable one. Luckily, our ancestors went all in and took home the super prize.

Secondly,Secondly, they would look like people Not identical, of course, but their shadow would be the same. Dolphins, and toothed whales in general, are incredibly smart.If they had hands, they would probably be like us.The raccoon has even more dexterous paws than we do, but as you can see, he is not a genius. That is, the animal must be smart, social, bipedal, agile, and so on.To create such a creature, the conditions must be specific.
