This is a very interesting article about some of the earliest-dated tools found that help describe the transition of humans from our ancestors to what we are in present day. Though we rely on various tools on a day-to-day basis, does the benefit gained from their use outweigh the cost of "missing out" on evolutionary pressures that people in the third world may experience?

Really interesting article. This idea is a bit of a stretch, but I wonder about the harm that some of our modern-day tools are causing us, besides a hindrance to natural selection. Texting, for example, may lead to instant communication, but also carpal tunnel syndrome. Although I don't think that cell phones are going anywhere, I wonder if this will ever have an evolutionary effect or if the harm will ever outweigh the benefits. - Hayley Hemstreet
ReplyDeleteAfter reading this, I am just wondering how it is that many people around the world - with no possible contact with each other - we able to create similar tools. That is how is it that so many tribes designed the arrow head the way we know it as, or decided to put it at the end of a stick? Not just tools, but to even everyday things, such as all the ancient civilizations and the "bowl" or spoon etc?

So this is another reason why evolution has slowed down so much. This makes a very interesting connection to one of the posts by Hayley Hemstreet on the R-Evolution blog entitled 'Have we stopped evolving?" It Check it out!
