Is personality influenced by genetics? New study detects more than a thousand variants in genes linked to individuality and identity

Is personality influenced by genetics? A new study detected more than a thousand variants in genes linked to human individuality and identity. The research seeks to better understand the factors that determine personality traits.

Psychologists measure these tendencies through the so-called "Big Five" dimensions: extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. Each trait exists on a spectrum and tends to remain relatively stable throughout adult life.

Scientists have known for a long time that personality is influenced by a range of factors, including DNA. The challenge has been deciphering the specific pathways through which the genetic code influences the course of a person's life.

To map this complex architecture, a group of scientists is working on research that aims to identify how genes contribute to personality. The study detected more than a thousand genetic variants associated with these traits, representing a significant advance in understanding the genetic basis of human individuality.

What species is this: ladder snake

A reader found a snake in Águeda, Aveiro, on August 29, and asked for help identifying the species. Herpetologist Diogo Parrinha responded that it is a ladder snake (Zamenis scalaris), completely harmless. This species can reach up to 160 centimeters and is the second snake with the largest distribution area in Portugal, being well distributed throughout the mainland territory up to 800 meters altitude. It is more visible between April and October, preferring habitats such as open oak and cork oak woodlands, especially in agricultural landscapes.

What species is this: wasp of the family Evaniidae

A reader photographed an insect in Monte Gordo, in the Algarve, and sent the image to the Wilder website for identification. Specialist Rui Andrade identified the animal as a wasp from the Evaniidae family, parasitic wasps specialized in cockroach oothecae (egg casings). The female lays her eggs inside the oothecae, where the larvae develop feeding on the cockroach eggs. The adults have a short and robust body, with a small and narrow abdomen, and are known for oscillating their abdomen up and down when active. Although they can be found in homes, they are not known to sting or bite humans.
