Aging can neutralize sex differences in the fruit fly brain
It is a well-known fact that weaker people cannot "invest" in sexuality to the same extent as their healthier counterparts
Antonino Malacrinò, one of the study's lead authors, now at the University of Regio Calabria in Italy, said: "Our results show that with age, gene expression in male and female brains becomes more similar, And both sexes contribute to this pattern
"The results also showed that this change was greater in males than in females," says Antonino Malacrinò
The fact that females vary less with age than males may be due to the fact that the link between investment in sex characteristics and reproductive success is not as strong in females as it is in males
Studies in other animals, including humans, which have focused on age-related changes in gene expression in one sex, have also given results pointing in the same direction
The findings of this study are reminiscent of those obtained in previous surveys
