537 biology and zoology May 28, 2016

People have probably heard that biology is "the study of life". Although this is close to the truth, it misses the mark. 'Bio' comes from the Greek word, 'bios' means "human life" or "course of (human) life’. Until recently, a biologist would have only have been thought or expected to study humans, though now the sense has been extended to ‘organic life’. What really means 'life' in Greek is 'zōē' and is related to 'zoology' from the word for animals, 'zōion'.
