Your Environment Could Be Changing Your IQ on a Genetic Level

The nature-versus-nurture argument of intelligence just got a lot more complicated with the discovery that the environment can modify the expression of a key gene in the brain, affecting intelligence far more than we previously thought. Such a finding may … Continue reading

Unraveling the gene-environment interaction

The field of epigenetics focuses on how the blueprint provided by genes is actualized, examining how experiences influence the way genes manifest themselves or are “expressed.” Using the tools of epigenetics, the studies in the special section move beyond the … Continue reading

On how some fitness-promoting genes during youth are harmful during aging

Autophagy is a ubiquitous catabolic process that causes cellular bulk degradation of cytoplasmic components and is generally associated with positive effects on health and longevity. Inactivation of autophagy has been linked with detrimental effects on cells and organisms. The antagonistic … Continue reading

Why haven’t we evolved immortality?

If evolution works by selecting for the most advantageous genes, it begs the question: why haven’t we evolved immortality? According to a decades-old hypothesis, certain genes that promote reproductive success also promote aging later in life, and now a study … Continue reading

Correlated genotypes in friendship networks

It is well known that humans tend to associate with other humans who have similar characteristics, but it is unclear whether this tendency has consequences for the distribution of genotypes in a population. Although geneticists have shown that  populations tend to stratify genetically, this … Continue reading

Brains work via their Genes just as much as their Neurons

It’s not headline news that our brains are the seat of our thoughts and feelings. The brain is a body’s decision-maker, the pilot of its actions and the engineer that keeps all systems going. The brain suits the body’s actions … Continue reading

How many Genes does it take to make a Person

We humans like to think of ourselves as on the top of the heap compared to all the other living things on our planet. Life has evolved over three billion years from simple one-celled creatures through to multicellular plants and … Continue reading

The Astonishing Creativity of Your Genes

The code that makes cells is more complex than it once seemed. The millimeter-long roundworm Caenorhabditis elegans has about 20,000 genes—and so do you. Of course, only the human in this comparison is capable of creating either a circulatory system … Continue reading

Challenges in Evolutionary Sociology and Biosociology

Scholars in the area of Evolutionary Sociology and Biosociology explicitly seek to examine the interplay of social and environmental factors with evolved biological factors and its implications for social behavior. It is a broad area covering a wide array of … Continue reading

In Social Bees and Loners, a Hunt for the Genes Behind Social Behavior

Her target is Lasioglossum albipes, an unusual species of the so-called sweat bee that is capable of two very different lifestyles. Depending on where and to whom they’re born, these bees live either largely alone, raising their own young, or … Continue reading
