Which herbivore has fingerprints so identical to those of a human that even with an electron microscope, it can be difficult to distinguish them?
Fingerprint objects; these include many primates, such as gorillas and chimpanzees, Australian koalas and aquatic mammal species such as the North American fisher. According to one study, even with an electron microscope, it can be quite difficult to distinguish between the fingerprints of a koala and a human. Koalas' independent development of fingerprints is an example of convergent evolution. Mark Twain's memoir "Life on the Mississippi" (1883), notable mainly for its account of the author's time on the river, also recounts parts of his later life, and includes tall tales and stories allegedly told to him. Among them is an involved,
Electron microscope Electron microscope An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000x whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.
