The Great Motivator Taste

Wasn’t it Columbus’ reason to discover America?

The sense of taste in humans, compared with that of other creatures, is poorly developed. For example, the threshold for tasting alcohol requires a 20,000 times greater concentration than that, which elicits a response in our olfactory receptors of the nose. Yet, we owe it to taste, not greed for gold or missionary zeal, that Columbus departed westward in search of a shorter route to the “Indies” and that Vasco da Gama a little earlier had successfully navigated around the tip of Southern Africa. European food in the Middle Ages must have been terribly bland and boring and to make it at least halfway palatable spices like nutmeg, cinnamon and cardamom, to name but three, were precious and needed from the Orient, from the “Indies”. —>—>

The Zoological History of Dragons & Co.

History of dragons

Dragons and sea-serpents play important roles in the mythologies of most of the world’s many cultures, from China and India to the Americas, from Greenland in the Arctic to New Guinea and Australia. It is obvious from the descriptions, the paintings and sculptures of dragons and sea-serpents that in the distant past fearsome and formidable snakes must have been the model for both, because the characteristics of that group of limbless reptilians are just too obvious to be overlooked. —>—>

Sex and the Environment

There is a connection between sex and the Environment

Did you know that the majority of the eels found inland in freshwater lakes and rivers are (or become) females, while those which do not migrate upstream but remain in the estuary are males (or become males)? It is still under investigation as to whether eels stay in these habitats because of their gender or their sex is, in fact, determined by the environment in which they mature. That the latter is entirely possible has been shown for a large number of fishes and reptiles. In fact, way back in 1961 as a school boy I must have been one of the first to take note of environmental sex determination in fishes through temperature, but I never published my observations, then for as the school boy that I was at that time I had no idea of scientific reports and publications and how to prepare them. —>—>
