I disagree. I love the article so a thumbs up for that. There's a reason why we rule this planet and it's because we're smarter. If you take 1 look at nature, you'll realise how dangerous even a red ant can be compared to us. A tiger within 2 years could take on 4-5 unarmed men in the wild.. who are fully grown. We take years to develop and can only defend ourselves with weapons which were built from our intelligence :)
