What prevents other animals/species from evolving and developing cognitively the same way humans have?
In: 145
I had a great science teacher way back in 10th grade who told us that evolution does not care about improving. It is just cares about being good enough to survive. Every now and then, a mutation occurs at the right time, allowing certain traits to exploit the world around them much better than other species. Sentience itself only has a limited role in preserving a species. While we might appear to be the smartest creatures around, able to harness the world around us at will, and apparently at the top of the food chain, make no mistake – if a worldwide nuclear holocaust was to occur, those stupid insects crawling around the ground will make it millions of years past the human race on the scale of time. I loved that teacher – he opened our eyes but kept us humble. God I feel old now.
