Fingerprints on humans, chimpanzees, and koalas primarily serve the same purposes - for grip and for touch sensitivity.

It had become lonely and was not under suspicion of a criminal offence. She holds a bachelor's degree in physics from Tufts University and has studied physics at the University of California, Berkeley. Some would say that their similarities are more the results of parallel evolution, but considering the distance and the time that separate the animals, and the uncannily similar animals they developed into on separate continents, they do display a gift for convergence.
