An article about crows using tools to find food. It’s true that monkeys do this but it could be attributed to their intelligence an learned behavior. However, its hard to imagine a crow to have learned behavior to the point of making tools.
Well there are other birds that use tools like the finches of the Galapagos Islands. I read your article and it is talking about an evolved behavior in a presumably subspecies of crow from New Caledonian Islands. Many behaviors are genetic in humans and other animals. It is the imprinted behavior in the genes that is passed down through the survival of the fittest. Learned behaviors are not passed down only the ability to learn them is. These crows have the tool using behavior in their genes because it helped them survive well and pass on the mutation.

birds can make nests…think about it…can you make a nest?

Mimicking behavior is not, necessarily, genetic.
Still, the behavior is observed in otherwise isolated groups of crows.

There exists a paper that shows that elephants in captivity, when brought to their ancestrol lands, will be able to follow the migrations of their ancestors. As I recall there is no other scientific explanation. I don’t really want to tlook for the paper but I know it can be found. Look for it, it might help the debate.

Web-making in spiders. Genetic programing has been observed and ‘proved’ for a long time. A surprising amount of behavior is built-in, even in humans.
