Where Does Probability Come From? (and randomness to boot)

I just returned from a cruise to Alaska. It is a wonderful, beautiful place. I zip-lined in a rain forest canopy, hiked above a glacier, kayaked coastal Canada and was pulled by sled-dogs. Anywho, as on many cruises, there was a casino, which is an excellent excuse for me to discuss probability. What is probability and where does it come from? Definitions are easy enough to find. Google returns: a measure of how likely it […]

Psychopharmacological Enhancement

The only ways to enhance the mind is to learn or evolve. Since evolution is out of our hands, all that is left is to learn. Drugs that purport psychopharmacological enhancement do not do what their name states: they may change certain psychological factors but there is no drug that will make you smarter. This would be to eat from the tree of knowledge. However drugs may be able to let you do things that […]

The Logic of Biological Relativity [draft]

How can we represent biological relativity in logical notation? Organism a is adapting relative to organism b Aab Organism b is adapting relative to a Aba Organisms a and b are adapting relative to each other Aab & Aba This schema is unsatisfactory because it describes the situation from an indeterminate outside perspective: a and b are said to be adapting relative to each other without regard to the observer describing the situation. Relativity applies […]

Relativity in Biology notes from 2005

It’s always interesting to see the start of ideas. Although I don’t have anything from the Spring of ’04 when I recall realizing biorelativity for the first time, I have found a file with a ‘last modified’ date of June12, ’05, the contents of which are below: Quantum Biology biology: the study of the physical attributes of life. the rate of mutation is constant, much as the speed of light organisms mutate. light shines. hence […]

Why Evolutionary Principles Cannot be Used to Support Racial Prejudices DRAFT

Evolutionary principles are sometimes used to justify racial prejudices. While no rigorous scientific study has yet proven one race to be inferior to any others it should be recognized that it is in principle impossible to prove racial superiority/inferiority and hence no study ever will. Firstly a note on the meaning of ‘more evolved’ and ‘less evolved’. Every species on the face of the earth today has been evolving for the exact same amount of […]

Evolutionary Drift, revisited yet again

With my recent paper on Measuring Fitness I realize that my previous responses to evolutionary drift, though not incorrect, may have not stated the solution particularly clearly. When fitness is defined and measured as described in the aforementioned article, evolutionary drift is irrelevant. The method of measuring the fitness of an organism or species makes no reference to any mutations whatsoever. Therefore evolutionary drift is no problem for the theory of fitness described here. If […]

Measuring Fitness

The basic premise is to measure fitness in a conceptually similar way to how we measure mass.  To measure mass we can use a scale to compare the effect of gravity on a test object to an object with an agreed upon mass, or we can compare the test object’s resistance to acceleration as compared to an object with an agreed upon mass.  These methods measure the ‘gravitational’ mass and ‘inertial mass’ respectively. Gravitational Mass […]

Blogged by The Philosophers’ Carnival #55, Sweet!

The Philosopher’s Carnival picked up my Relativity in Evolutionary Biology! Completely cool. And I won the shortest description contest- take that all you people who write things that can be summarized. And hyphenation to boot. Props to the editor who used an archaic device to help me out in lieu of delving into unruly philosophy of science sure to scare people. It’s all relative Noah Greenstein has written a well-worth-a-peek post on ‘Relativity in Evolutionary […]

General Relativity in Evolutionary Biology DRAFT

EDIT, July 2015: See the full draft at the phil-sci archive: http://philsci-archive.pitt.edu/11557/ Also check out my other Research. Below are old notes: —- I’ve discussed relativity in evolutionary biology with regards to uniform change but, as with the Special Theory of Relativity in physics, we want a theory that covers all change. This means that insofar as relativity applies to biology under uniform motion, i.e. when a species is reproducing in a regular fashion, we […]
