The first primate-like creatures appeared at the end of the Mesozoic era, roughly 65.5 million years ago. Fossil records indicate that these early organisms appeared around 55 million years ago, though more recently found fossils indicate they may have come even earlier. These animals were very ...
There are many examples in the human body alone. The tailbone is the remnant of an ancestor's tail, and the ability to wiggle your ears is leftover from an earlier primate that was able to move their ears around to pinpoint sounds. Plants have vestigial traits as well. Many plants that...
A more recent classification of primates shows that the primates may be grouped into wet-nosed primates and dry-nosed primates. The wet-nosed primates make up the suborder Strepsirrhini whereas the dry-nosed primates belong to the suborder Haplorhini. The suborder Strepsirrhini consists of non...

The localization of MAO A and the effects of its knock-out or inhibition in animals are consistent with the observed antidepressant effects of MAO A inhibitors. Neuroimaging with harmine, a tight-binding MAO inhibitor, demonstrated increased MAO-A levels in the cortex, striatum and midbrain of ...

The existence and use of culture depends upon an ability possessed by humans alone. This ability has been called variously the capacity for rational or abstract thought, but a good case has been made for rational behaviour among subhuman animals, and the meaning of abstract is not sufficiently ...
Culture, as noted above, is due to an ability possessed by man alone. The question of whether the difference between the mind of man and that of the lower animals is one of kind or of degree has been debated for many years, and even today reputable scientists can be found on both side...
