A new study elaborated by a team of researchers argues that the number of mutations tied to the aging process is considerably higher than previously thought. It also provides additional research for a theory focused on mutation types and aging.
Many people accept thought their lives that death is inescapable, as our bodies will deteriorate in time, and the moment of demise will arrive at some point. However, researchers interested in evolutionary biology are fascinated by the roots and factors that are behind the aging process.
The aging paradox
Aging is a phenomenon that defies evolution, a trait that makes it even more interesting. While evolution has led to the development of new traits and the correction of many flaws, the aging process continues without problems. There are two theories tied to two different types of mutations that can cause aging.
The two theories argue that mutations lead to the appearance of negative effects as an organism becomes older. However, they won’t cause any harm during the early stages of life. Researchers haven’t managed to determine which of the two types plays a major role in the aging process.
A new theory surfaced in recent years, arguing that aging is caused by mutations that have negative effects while young, with the effects becoming even stronger as a person becomes older. In this case, many of the mutations could cause negative effects as soon as they appear.
The team of researchers tested the theory by exploring the effects of 20 different mutations across fruit flies, with one control group for each group affected by a mutation. Results have inferred that mutations that favor negative effects early in life can also contribute to aging, and it seems that they are considerably more common.
The study has sparked the interest of the scientific community, and it has been published in a scientific journal.
