Homology
.. Is the central concept of all biology. Whenever we say that a mammalian hormone is the ‘same’ hormone as a fish hormone, that a human gene sequence is the ‘same’ as a sequence in a chimp or a mouse, that a HOX gene is the ‘same’ in a mouse, a fruit fly, a frog, a human – even when we argue that discoveries about a worm, a fruit fly, a frog, a mouse, or a chimp have relevance to the human condition –we have made a bold and direct statement about homology. The aggressive confidence of a modern biomedical science implies that we know what we are talking about.”- David B. Wake
