You guys still don't get it. The mutation in this case make the plant less effencient. In essence the plants are in a sense devolving as they 'evolve' so as to modify themselves to fit the environments they now live in. If a plant could orginaly process 100w aday and now in a more modern form can only process 75w aday then the 'mutation' speaks against evolution especially since we are told by the same science the planet is getting warmer.

My question from the beginning that can not be explained by mutation is if the daily amount of solar input of a given species is 75w at full contact, then how is it possible that some of the oldest species of plant life can successfully process so much more solar energy when made available?

This could be one of many many reasons.. Only data can lead to conclusions. What plant are you referring to?
Also, looksie.

Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's surface that was observed for several decades after the start of systematic measurements in the 1950s. The effect varies by location, but worldwide it has been estimated to be of the order of a 4% reduction over the three decades from 1960–1990. However, after discounting an anomaly caused by the eruption of Mount Pinatubo in 1991, a very slight reversal in the overall trend has been observed.[1]
Global dimming is thought to have been caused by an increase in particulates such as sulfate aerosols in the atmosphere due to human action.
It has interfered with the hydrological cycle by reducing evaporation and may have reduced rainfall in some areas. Global dimming also creates a cooling effect that may have partially masked the effect of greenhouse gases on global warming.

I was going to wait and see who else commented or kudoed you on this before I said something, but decided to call you on it instead.
You do know... Evolution supposedly happens over the course of millions and millions of years right? It's not something that could have made the changes we are talking about since mans entry into the Industrial Age. So whether or not it was brighter in the 1950s or even at the turn of the 19th century it makes no difference to this particular discussion.
