The research team, headed by Dr. Sterns, reported on such characteristics as weight, height, cholesterol, childbirth, and menopause of these women.
The conclusions are:
•
Weight and onset of menopause will increase by about 1%
• Height and age at first childbirth will decrease by about 1%
• Cholesterol levels will decrease by about 4%
The conclusions of the study will be reported in an upcoming issue of the journal
Proceedings of the National Academy of Sciences (
PNAS).
The ScienceNOW article states,
“These slow rates of evolution are on par with what evolutionary biologists see in other species' traits.”
Dr. Stearns comments,
"The take home message from this is that the women of Framingham are pretty average--they're just like the other plants and animals other evolutionary biologists have studied.” [ScienceNOW]
The researchers also stated that their data only applies to women of northern European descent. They will be performing further research to determine if these conclusions hold, in general, for all women.
