Cooking is one of my favorite hobbies.
Cooking is also refered to as cookery and is the art, technology, science, and also craft of preparing food for consumption! This can be done with or without heat.
I've never heard of it referred to as cookery before.
Well did you also know preparing food with heat/fire is relatively unique to humans?
Yes I'd assume so. I really don't see animals using fire.
Cooking with fire may have started roughly 2 million years ago but archarological evidence doesnt reach past 1 million years ago.
Were the cavemen from about a million years ago?
Im not sure as im not really a biology scientist so i could not answer than but i can say new inventions and technologies such as pottery for holding and boiling water expanded cooking techniques. I bet the person who discovered boiling was proud!
