AGW and CO2 are altering Evolution



Evolution is a theory that has not been proven ... nor demonstrated in any form. Global Warming is a political propaganda mechanism that is not demonstrated by science but rather promoted by fear mongering in order to further subjugate the "little people" of planet earth under more rules and regulation ... greatly diminishing the health and well being of billions of humanity.

Now ... the next step in the dream works of hype and fear mongering ... CO2 has been determined that it "might" alter the coming eons of evolution?

Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the Univ. of Michigan suggests.

The research focused on the effects of elevated carbon dioxide on common milkweed, Asclepias syriaca. Milkweed is one of many plants that produce toxic or bitter chemical compounds to protect themselves from being eaten by insects. These chemical defenses are the result of a long history of interactions between the plants and insects such as monarch caterpillars that feed on them.

Plant defenses—and insect eating patterns—also respond to environmental factors such as rising carbon dioxide. This suggests that elevated carbon dioxide could affect plant evolution by altering the "selection pressure" that plant-eating insects exert on plants.

Selection pressure, the driving force of evolution, induces changes in the genetic composition of a population. It works like this: if insects inflict too much damage on plants, the plants can't reproduce as successfully. This sets up a situation in which any plants that, by chance, have inherited insect-deterring traits are at an advantage. Because of that advantage, such traits are likely to spread through the population, urged on by "pressure" from the insects.....

These people that dream this stuff up would make excellent SciFi writers.

Give me a break.
