Pandora’s Seed: The Unforeseen Cost of Civilization
The cockroach as we know it has been around for ~140 million years. That’s a rather long run. The evolutionary design of the cockroach seems to be well suited to avoiding obsolescence; it’s withstood the test of time. I suspect that the particular example of the roach is often used to illustrate the blindness of […]
More exercise = more I.Q.?
Interesting post by Gretchen Reynolds reviewing the evidence on exercise and intelligence. The title is “Phys Ed: Can Exercise Make Kids Smarter?”, so this is definitely seen as something which is “actionable” in a public policy sense, especially in light of the increases in obesity among young people. Intuitively I think most people are going […]
Diseases of the Silk Road
Nature has two papers out about something called “Behçet’s disease.” It has apparently also been termed the “Silk Road Disease”, because of its associations with populations connected to the Central Eurasian trade networks.Though described by Hippocrates 2,500 years ago, apparently it was “discovered” only in the 20th century by a Turkish physician. The reason that […]
Personal genomics & the state
Dr. Daniel MacAthur & Dan Vorhaus offer their takes on the recent hearings in Congress on the direct-to-consumer genomics industry, A sad day for personal genomics & “From Gulf Oil to Snake Oil”: Congress Takes Aim at DTC Genetic Testing. I guess I lean toward light regulation. I don’t think that DTC personal genomics will […]
Disease as a byproduct of adaptation
How we perceive nature and describe its shape are a matter of values and preferences. Nature does not take notice of our distinctions; they exist only as instruments which aid in our comprehension. I’ve brought this up in relation to issues such as categorization of recessive vs. dominant traits. The offspring of people of […]
Eating like your ancestors
The ideas of gene-culture coevolution have percolated all the way to the foodie-sphere, over at Epi-Log at Epicurious, The Health Trend of the Future: The Ethnic-Group Diet?:
So, maybe at some point in the future, a visit to the doctor will involve a full genetic workup followed by a prescribed diet tailored to our individual makeup. […]
Low IQ correlated with cardiovascular disease?
Second Only to Cigarette Smoking in Large Population Study:While lower intelligence scores — as reflected by low results on written or oral tests of IQ — have been associated with a raised risk of cardiovascular disease, no study has so far compared …
Where the fat folks live
Since it’s after Thanksgiving and I’m feeling bloated, I figure a follow up to the post on obesity and diabetes might be apropos. I want to focus on obesity. I have the raw county-by-county data, but obviously it isn’t broken down by race. But, I do ha…
