Dear editor:

Dr. William Brown’s very interesting column, “Differences between Neanderthal and human brains” (Feb. 23) was certainly enlightening.

However, the long and descriptive list of discoveries and scientific procedures did not produce anything more that a vague opinion on substantial differences.

A single sentence in the article appears to “suggest” a change in intelligence over 30,000 years.

I quote: “That’s a startling result for one gene and suggests the brains of Neanderthals were not as capable as those of modern humans.”

Perhaps future study will “suggest,” even prove, otherwise.
