- Can you think of any other features that humans no longer need? What function did it hold in the past? Here are a few to get you started:
- With the availability and accessibility of developing technology, we are not as disadvantaged if we are lacking a particular trait. For example, poor eyesight is improved through the use of glasses or laser eye surgery. Brainstorm a few different improvements technology has had on our natural deficiencies. Will technology affect the course of natural selection? Are humans still evolving by Darwin's natural selection?
