Babble rousers

I read with interest your article "Building blocks of talk" (SN: 5/27/00, p. 344). I think it's more than coincidental that the sound repertoire of babbling babies, compared with the speech sounds in a diversity of languages across the world, lends credence to the idea that there was a mother tongue that goes back to prehistoric times.

Readers of the Bible will recall that it was after the fall of Babel that people separated and spoke in many languages. (Our language contains the interesting coincidence of Babel and babble having the same sound but a slight difference in spellings.)

Students of language, such as myself, are fascinated by the occurrence in diverse languages of words that bear remarkable similarity to each other. It would be interesting to study the idiosyncratic speech that often develops with twins to see if the language they develop bears similarities to the language we speak in all or any respects.

I wonder if the researchers considered that the similarity in babbling among the various languages may have actually originated from the parents--not the babies. In most cultures, Mom, Dad, grandparents, and other adults seem to initiate the baby talk as they seek to solicit responses from a newborn. Perhaps the commonality here is that the babies are receiving imprints from the adults around them and are imitating their behavior. There may not be any controlled way to test this. Keeping newborns in a lab with only graduate-student-level speech in their environment wouldn't be considered ethical.

Teen years loom

The initial conclusions of the study of Romanian children raised in orphanages and adopted in Britain ("Attachment disorder draws closer look," SN: 5/27/00, p. 343) would seem to this adoptive parent to be prematurely optimistic. A study based on subjects aged only up to 6 years can hardly conclude that severe deprivation "doesn't inevitably undermine social functioning." On the basis of the experience of our family and others that we know and have read about, it seems likely that the children's conditions will worsen when they enter the teen years, leading to antisocial and sometimes self-destructive behavior.

Insect aside

In an article entitled "Biodiversity may lessen Lyme disease" (SN: 6/17/00, p. 395), you mention that Lyme disease is the most common "insect-borne" disease in the United States. Since Lyme disease is spread by ticks, and ticks have eight legs and are arachnids, Lyme disease is not insect-borne.

Cosmic candy

We're not surprised they found sugar in the middle of a Milky Way ("Sugarcoated news arrives from space," SN: 6/24/00, p. 405)!
