Discussion Overview

The discussion centers around the nature of fingerprints in identical twins, exploring whether they are determined by genetics, development, or a combination of both. Participants examine the factors influencing fingerprint formation, including stochastic processes and environmental influences.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants assert that the fingerprints of identical twins are not identical, suggesting a distinction between genetic and developmental influences.
  • One participant proposes that fingerprints are formed due to stochastic factors, implying randomness in their development.
  • A participant questions the randomness of fingerprint formation, wondering if stochastic processes could lead to similarities in certain qualities.
  • Another participant suggests that environmental factors, such as temperature and contact with surfaces, may influence fingerprint development.
  • A later reply challenges the idea that environmental factors would lead to each finger having a different print, raising questions about the consistency of fingerprints across fingers.
  • A participant shares a link to an article discussing why identical twins have non-identical fingerprints, indicating a resource for further exploration.

Areas of Agreement / Disagreement

Participants generally agree that identical twins do not have identical fingerprints, but multiple competing views remain regarding the specific influences on fingerprint formation, including genetic, developmental, and environmental factors.

Contextual Notes

The discussion includes assumptions about the role of stochastic processes and environmental influences, but these factors remain unresolved in terms of their exact contributions to fingerprint uniqueness.

Are fingerprints the same for twins? That is, are they based on development, on the genetic code, or a combination of both? Its probably a dumb question, but it had me wondering.

The fingerprints of identical twins are not identical. So sayeth Columbo, and it was so.
 
Fingerprints are formed due to stochastic factors.
 
Thanks ChemicalSuperfreak and Monique. I really appreciate it. I knew they didn't have the same fingerprints -- I just was curious on how features can look the same and not be "genetically" the same, that's what I was aiming at.

Addendum: I have a question for Monique. Why would guesswork (stochastic) cells for the fingerprints be random? And even if they are random isn't there some chance (very unlikey) that they could resemble multiple qualitites?

Thanks again.
 
I assume they would be affected by the environment they are in direct contact with... they are afterall external, vulnerable to touching things, vulnerable to temperature differences, water wrinkling them differently and so on...

If that were the case, each of our fingers would have a different print. Right?
