Broadcast (2001) Survival of the fittest: Raw competition? Intense cooperation? Both are essential. Interactions between and within species are among the most powerful evolutionary forces on Earth, and understanding them may be a key to our own survival. Evolution determines who lives, who dies, and who passes traits on to the next generation. The process plays a critical role in our daily lives, yet it is one of the most overlooked and misunderstood concepts ever described. The Evolution series goals are to heighten public understanding of evolution and how it works, to dispel common misunderstandings about the process, and why it is relevant to all of us.

The Evolution project's eight-hour television miniseries travels the world to examine evolutionary science and the profound effect it has had on society and culture. From the genius and torment of Charles Darwin to the scientific revolution that spawned the tree of life, from the power of sex to drive evolutionary change to the importance of mass extinctions in the birth of new species, the Evolution series brings this fascinating process to life. The series also explores the emergence of consciousness, the origin and success of humans, and the perceived conflict between science and religion in understanding life on Earth.

Love this video. I'm a scientist working in the field of human colorectal cancer and I can tell you that evolution of germs and our own human bodies (more precisly our DNA) is more intertwined than most people realize.

In any case..... I'm also sure that at some point a religious nut will see this and say.... God did it :):):)

I wish there were more vids like this, GOOOOOOD JOB!

I'm scared for the fungi who might now be more easily infected by bacteria with anti-biotic resistance.

great documentaries. we still need to learn so much more. humanity is afflicted with diseases and other types of sufferings. science is our best tool to combat this. but i am saddened and annoyed that majority of the people go to their mythical gods to solve their problems and just ignore science. this is a huge mistake.

So... the newts that survive to procreate were spared because of the heightened toxicity in their species, which caused the snakes to pay a price in vulnerability when preying on the species, thus reducing the frequency of predation?
