And as these stories unfold, one becomes familiar with the primary ideas and events in the rise of modern evolutionary thinking.

Darwin's theory now forms the basis of all modern evolutionary thinking, of course.

"Genetics and evolutionary thinking have to be incorporated if we're going to talk about long-term sustainability of these species," he said.

However, systematics was an active field of research long before evolutionary thinking was common.

It was, of course, immediately adopted by the extreme left, which had, indeed, long provided a powerful component of evolutionary thinking.

If this is supported by further investigations, scientists say, it could overturn conventional evolutionary thinking on the relationship of brain size to intelligence.

These latter ideas are remarkably consistent with the most current evolutionary thinking in biology and anthropology.

The last two have points in common and represent recent trends in evolutionary thinking.

For example, evolutionary thinking is key to life history theory.

This intellectual turmoil is not evidence of the weakness of the evolutionary thinking, as some critics have said.
