Given a critical change in the environment, how exactly do species adapt? 

Hydraulic fracturing, commonly called fracking, is a way to extract natural gas from shale rock, by using a modern process to inject a high-pressure water mixture at the rock to release the gas inside. By all accounts it has been an environmental boon, responsible for causing energy emissions from coal to plummet back to early 1980s levels without causing energy prices to rise and harm poor people.

Mothers are already responsible for propagating the species, a thankless job which men wisely avoid in all ways, but now they may be tasked with a better diet and exercising more also, because it has been directly associated with a range of improved outcomes at birth by researchers from the University of Adelaide.

They say it is the  biggest study of its kind two papers were published on the findings in BMC Medicine.
