Explanations: answer key for all 10 questions

Q1: When do fingerprint ridges form?
Answer: Before birth
They develop in the womb.
Q2: Which pattern is most common?
Answer: Loops
Whorls come second.
Q3: Which main pattern is least common?
Answer: Arches
Only a small share have them.
Q4: Do identical twins share fingerprints?
Answer: No, their prints differ
Womb conditions vary.
Q5: What are small features like ridge endings called?
Answer: Minutiae
Experts compare them.
Q6: Who suggested using fingerprints to identify criminals in 1880?
Answer: Henry Faulds
He was a Scottish doctor in Japan.
Q7: Which scientist studied fingerprints and their uniqueness?
Answer: Francis Galton
He classified patterns.
Q8: Where was a murder first solved using fingerprints in 1892?
Answer: Argentina
Juan Vucetich led the work.
Q9: Which animal has fingerprints very similar to humans?
Answer: Koala
Experts can confuse them.
Q10: What is the rare condition of having no fingerprints?
Answer: Adermatoglyphia
It is sometimes called immigration delay disease.

Patterns Written on Your Fingertips

Fingerprint ridges form before birth, shaped by pressures and growth in the womb. The three main patterns are loops, the most common, whorls and arches, the least common. Even identical twins have different fingerprints, because conditions in the womb vary.

Experts compare tiny details called minutiae, such as ridge endings and splits. In 1880 Scottish doctor Henry Faulds, working in Japan, suggested using fingerprints to identify criminals, and Francis Galton studied their uniqueness and classified patterns. In 1892 in Argentina, a murder was first solved using fingerprints, in work led by Juan Vucetich.

Koalas have fingerprints so similar to humans' that experts could confuse them. A rare genetic condition, adermatoglyphia, leaves people with no fingerprints at all, sometimes causing trouble at border checks.
