Why are most identical twins easier to tell apart as they get older?
* Shared Environment and Lifestyle: Identical twins share the same DNA, and often grow up in very similar environments with similar lifestyles. This can lead to them developing similar habits, expressions, and even physical characteristics.
* Convergent Phenotype: While identical twins start with the same DNA, their genes are not always expressed in exactly the same way. Over time, their experiences can influence their gene expression, causing their appearances to become more alike. This is known as "convergent phenotype."
* Shared Habits: Twins often share habits like posture, facial expressions, and mannerisms, making them look even more alike.
* Shared Aging: The aging process affects individuals differently, but identical twins share the same genetic predisposition to aging, which can contribute to a more similar appearance over time.
Important Note: It is important to remember that every individual is unique, and there are always exceptions. Some identical twins may maintain distinct features throughout their lives.
In short, the shared genetics, similar experiences, and convergent phenotype make it more challenging to distinguish identical twins as they age.
