I teamed up with the well-known developmental psychologist David S. Moore to list eight facts about genes, twin studies and the heritability statistic that may come as a surprise to many people, even biologists!

A recent study looked at the financial portfolio of twins to gain a better understanding of the affects of nature vs. nurture on spending habits. The results.

It's an age-old question: can we change the personalities we're born with? Now, a new study from the University of California Riverside is weighing in...

What this study suggests is quite provocative enough for now: take good enough care of yourself, and even your genes will get a makeover.

Rather than lots of fancy features, it is likely that what humans enter the world with is a general ability to learn. We have an amazing ability to be able to pick up on various things and group them together.
