Why do identical twins have different fingerprints?

“there is a 50% probability of coincidental fingerprint matches in populations of 14 million, rising to near certainty at 40 million.”

“The odds of having the same finger print as someone else is 1 in 64 billion.”

“Experts say the odds of two unrelated people having identical fingerprints are less than one in 64 billion.”

“the odds of sharing the same fingerprint with another are 1 in 64 billion!”

“The probability that two sets of fingerprints are identical is one in 64 billion according to the studies of Francis Galton in 1982.”

“Even identical twins, who have the same DNA, have different fingerprints.”

“It is believed that the environment of the womb has a direct influence on the development of fingerprints.”

“This finding suggests that parental environmental factors may influence the fingerprints of the offspring.”

“Scientists generally agree that closely related species like gorillas, chimpanzees and orangutans have ridge patterns on fingers and toes”

“Noseprints are the primary way that individual Gorillas are able to be identified & monitored”

“Koalas have fingerprints that are so similar to humans' that even under a microscope, it's hard to tell them apart.”

“Koalas have fingerprints that are almost identical to humans'!”

“It turns out that fingerprints are an excellent example of convergent evolution.”
