Summary:Charles Darwin should be very honored to have his ideas on natural selection help resolve one of the most troubling questions in quantums mechanics. In quantum mechanics particles exist in so-called supersposition states in which they have many mutual contradictory properties.
Questions:Natural selection/Evolution
How is natural selection or evolution illustrated in this article? By answer troublesome questions
How does this support Darwin original findings? It answers questions that have been around for a long time
List three things you learned from this article in your own words.
1.Charles Darwin's ideas are finally being put into good use
2.Experiments have led to new discoveries
3.Questions from long ago are now helping current issues
What impact would the absence of this organism have on the ecosystem? Certain questions will not be answered

Handsome By Chance: Why Humans Look Different From Neanderthals
http://www.sciencedaily.com/releases/2007/08/070813101018.htm
Summary: The article is talking about how neanderthals and humans skulls are very different. However they don't believe it is natural selection. They believe that random changes occured because of the isolation between the two.
Questions: How is natural selection or evolution illustrated in this article? The article is comparing neanderthals skull with a human skull.
How does this support Darwin original findings? Yes
List three things you learned from this article in your own words. That the differences occured because of isolation, also that these two species have been isolated for a while, and that our late relatives have nothing in common with us.
What impact would the absence of this organism have on the ecosystem? it would basically create a new ecosystem because a whole species would be gone.

St. Bernard Study Shows Human-directed Evolution At Work
http://www.sciencedaily.com/releases/2007/10/071024083652.htm
The article talks about the evolution of a St Bernard's skull. This reason is best described in selection breeding. Breeders choose the dogs that best suit their own standards. The breeders may have also applied selection.
How is natural selection or evolution illustrated in this article? By the changing of a St Bernard's skull over 120 years.
How does this support Darwin original findings? It goes right along with it.
List three things you learned from this article in your own words. That humans could cause evolution in different species. A species could change in such a short time. That the St Bernard was European.
What impact would the absence of this organism have on the ecosystem? This animals save lives and many would die.

Evolutionary 'big bang' gave rise to flowering plants

Summery:Millions of years ago, a atom was split causeing the big bang.The big bang started life in the univerce.140 million years ago all the plants were created from the big bang.Today our plants evolved from these big bang plants.
Questions:How is natural selection or evolution illustrated in this article?Plants evolved millions of years ago from plants that came from the big bang
How does this support Darwin original findings?It dosnt.
List three things you learned from this article in your own words.Plants came from the big bang,all plants are related,and plants are millions of years old
What impact would the absence of this organism have on the ecosystem?There would be no life if there wasnt any plants.

Present-day Species Of Piranha Resulted From Marine Incursion Into Amazon Basin
Link:http://www.sciencedaily.com/releases/2007/12/071203131505.htm
Natural Selection works in wierd ways. It changes an animal according to their environment, what they eat, and what dangers they face. The piranha was changed according to their environment. They changed in order to survive.
Natural selection/Evolution
How is natural selection or evolution illustrated in this article?the piranha was changed to live in its environment
How does this support Darwin's original findings?it matches it
List three things you learned from this article in your own words.piranhas didn't always live in South America, they weren't always the same, they changed their DNA
What impact would the absence of this organism have on the ecosystem?the rivers of South America ould be polluted with dead bodies
