The Danger of Teleological Accounts of Evolution

It's important to remember that arguments over evolutionary mechanisms often depend on the deeply held convictions of evolutionary biologists—after all, biologists are people, too! Almost everyone is reluctant to let go of deeply held convictions. Many biologists, in particular, are still attracted to teleological…

Mindfulness Meditation Reduces Cognitive Rigidity

Two experiments examined the relation between mindfulness practice and cognitive rigidity by using a variation of the Einstellung water jar task. Participants were required to use three hypothetical jars to obtain a specific amount of water. Initial problems were solvable by the same complex formula, but in later…

Individuals VS Species

The assumptions of population thinking are diametrically opposed to those of the typologist. The populationist stresses the uniqueness of everything in the organic world. What is true for the human species,–that no two individuals are alike, is equally true for all other species of animals and plants ... All organisms…

Think in Letters Not Figures

I was just going to say, when I was interrupted, that one of the many ways of classifying minds is under the heads of arithmetical and algebraical intellects. All economical and practical wisdom is an extension or variation of the following arithmetical formula: 2 2=4. Every philosophical proposition has the more…

Humans share 98.5% of our genes with chimpanzees

The genome is not a blueprint for constructing a body; it is a recipe for baking a body. As the hox story illustrates, DNA promoters express themselves in the fourth dimension; their timing is all. A chimp has a different head from a human being not because it has a different blueprint for the head, but because it…

Nature Uses the Same Materials and Forms in Life

We know that nature invariably uses the same materials in its operations. Its ingeniousness is displayed only in the variation of form. Indeed, as if nature had voluntarily confined itself to using only a few basic units, we observe that it generally causes the same elements to reappear, in the same number, in the…

The Biological Species Concept (BSC)

And when we think of why we feel that brown-eyed and blue-eyed humans, or Inuit and !Kung, are members of the same species, we realize that it’s because they can mate with each other and produce offspring that contain combinations of their genes. In other words, they belong to the same gene pool. When you ponder…

Are There Bacteria Species?

It may very properly be asked whether the attempt to define distinct species, of a more or less permanent nature, such as we are accustomed to deal with amongst the higher plants and animals, is not altogether illusory amongst such lowly organised forms of life as the bacteria. No biologist nowadays believes in the…

Mendelian Genes are All-Or-Nothing

A Mendelian gene is an all-or-nothing entity. When you were conceived, what you received from your father was not a substance, to be mixed with what you received from your mother as if mixing blue paint and red paint to make purple. If this were really how heredity worked (as people vaguely thought in Darwin's time)…

A Succinct Definition of a Meme

For something to count as a replicator it must sustain the evolutionary algorithm based on variation, selection and retention (or heredity). Memes certainly come with variation - stories are rarely told exactly the same way twice, no two buildings are absolutely identical, and every conversation is unique - and when…
