Emotion + Reason May Be Evolution’s 1-2 Punch
Scientific American video explains the evolutionary value of human emotions.
So often it seems like our hearts get in the way of our minds. We don’t want to deprive ourselves of the positive feelings, like joy and excitement, but emotions overtake us and can totally get in the way of our clear thinking. Why must we be their puppets? We think of emotions as being vestigia of our primitive selves, at odds with our big, capable modern brains. But maybe that’s not right. From an evolutionary perspective, our wild emotions may be prerequisites for rational thought.
So even though we rarely need to flee from a saber-tooth tiger these days, it’s still a dangerous world. And lust? Sorry, love? Some things never change.

You can say 'no' to things, and you should. Do it like this.
- Give yourself permission to say "no" to things. Saying yes to everything is a fast way to burn out.
- Learn to say no in a way that keeps the door of opportunity open: No should never be a one-word answer. Say "No, but I could do this instead," or, "No, but let me connect you to someone who can help."
- If you really want to say yes but can't manage another commitment, try qualifiers like "yes, if," or "yes, after."
"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."
- The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
- Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
- Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.
Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
