The evolutionary and ecological benefits of asteroid and comet impacts [An article from: Trends in Ecology & Evolution]

This digital document is a journal article from Trends in Ecology & Evolution, published by Elsevier in 2005. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
Commonly viewed solely as agents of destruction, asteroid and comet impact events can also have a beneficial influence on processes from the molecular to the evolutionary scale. On the heavily bombarded early Earth, impacts might have delivered and caused the synthesis of prebiotic compounds that eventually led to life. At the organismal and ecosystem level, impact events can provide new habitats through the shock processing of target materials and by enhancing water availability, such as within intracrater lakes. At the evolutionary level, by destroying entire groups of organisms, impacts might have been instrumental in enabling the rise of new groups, such as the dinosaurs and mammals. Here, we synthesize the emerging literature on the beneficial effects of impacts to provide a novel perspective on these extraterrestrial agents of biological change.

What would happen if an asteroid hit the earth?

Posted on July 31, 2011 by admin| 7 Comments

I had seen an article on Yahoo saying that Obama really wanted NASA to concentrate on meeting a certain asteroid that scientists believe may have a chance of colliding with the earth in 2025. I was wondering if ALL of life on earth would cease to exist or just a portion? Is it even possible that they can throw it out of our orbit? I have seen the movie “Deep Impact” but that was a comet they were talking about!

How can this be true about the dinosaurs, when fossil evidence shows that there were almost no dinosaurs?

Posted on July 29, 2011 by admin| 4 Comments

when the comet finally did hit the earth, no fossils of dinosaurs that is, but in this article they are saying that the asteroid/ comet took them all out, this makes no sense, and is inconsistent with the fossil evidence showing that around the time that the impact was made, that there were almost no fossils of dinosaurs even left? What is this article really saying? http://news.yahoo.com/s/nm/20100304/sc_nm/us_dinosaurs_asteroid
