Infact
64 / 100
Mostly True

Koala fingerprints are almost identical to human ones, sharing ridge patterns, pores, and fine details, making them hard to distinguish under a microscope.

Infact verdict: Mostly True (64/100).

The claims about koala fingerprints being similar to human fingerprints are supported by multiple sources. Koalas do have fingerprints that are almost identical to humans, including similar ridge patterns and fine details. However, there is no evidence that they have confused crime-scene investigators. The similarity is due to evolutionary adaptations for tree climbing and leaf manipulation.
