It seems likely to me since the first tools we used as primates-early man. Think about it, those early, pre-homosapien primates who have mutated an inheritable trait which makes them smart enough to discover the benefits of rocks, sticks etc. to enhance their ability to gather food will therefore survive longer to have more offspring (more of the better) than those without the trait. The evolutionary process continues to favour the idea of tool use, making more advantageous cognitive-related mutations possible, the primates get smarter, improvements to tools are made, natural objects better suited for tools are collected and used and new types of tools are made. And so it goes on. Something like this I not only suggest affects the progress of the human genome positively (human brain) but also negatively like our lack of body hair from clothes and I read somewhere that because of our use of fire to cook food from millions of years ago, the enzymes in our digestive systems have been altered. I think this also means because of prosthetics, the importance of keeping our natural teeth decreases and so future generations will suffer less dental pain. Your thoughts?
