Scientists Look At Those In Evolutionary Race Who Don't Make It 'Out Of The Gate', ScienceDaily
In the race of evolution, scientists until now have only looked at winners and losers. Now, they've come up with a way to look at the contenders who never made it out of the gate. It's the organisms -- in this case lizards -- that die early in life, before scientists can even assess what they might bring to the reproduction game, and that have gone uncounted in the effort to quantify genetic fitness. This group has been dubbed the "invisible fraction." (...) "Measuring the invisible fraction is important because some organisms don't make it to adulthood," (...).
