Why I have an extra-terrestrial ancestor

چکیده
The aim of this note, popular in nature, is to generate some interests in fuzzy logic and approximate reasoning theory. To do this we show that fuzzy logic is an useful tool to give a solution to some famous paradoxes as the Heap paradox, the Bald Man paradox and Poincaré paradox of the indiscernibility (see Goguen [1968/69], Höhle [1991], Gerla [2008]). Also, we suggest new paradoxes. These paradoxes show that difficulties related with the vagueness arise also in two basic fields of the scientific activity, physics and evolution theory, and not only in the everyday activities.

Origin of human bipedalism: The knuckle-walking hypothesis revisited.
Some of the most long-standing questions in paleoanthropology concern how and why human bipedalism evolved. Over the last century, many hypotheses have been offered on the mode of locomotion from which bipedalism originated. Candidate ancestral adaptations include monkey-like arboreal or terrestrial quadrupedalism, gibbon- or orangutan-like (or other forms of) climbing and suspension, and knuck...
متن کاملPredicting what extra-terrestrials will be like: and preparing for the worst.
It is difficult to imagine evolution in alien biospheres operating in any manner other than Darwinian. Yet, it is also widely assumed that alien life-forms will be just that: strange, un-nerving and probably repulsive. There are two reasons for this view. First, it is assumed that the range of habitable environments available to extra-terrestrial life is far wider than on Earth. I suggest, howe...

Many hypoth...

متن کاملWhy and How Is Compassion Necessary to Provide Good Quality Healthcare?
Recent disclosures of failures of care in the National Health Service (NHS) in England have led to debates about compassion deficits disallowing health professionals to provide high quality responsive care.
