Extinction Extinction is the termination of evolutionary lineage. The most common extinction event is the loss of a species. There are many reasons why a species might die out.

Daruwalla finds that there is violence in the very air‚ and that this violence is an indication of the mass hatreds drifting across the moon and hovering‚ poised like a cobra. He looks for a fang that darts‚ a hood that sways‚ and eyes that throw out a reptile hate. Here we have horrifying serpent-imagery to indicate the kind of hatred which burns in human breasts and drives them to fight one another. So many people die in the violence that mortuaries are filled with corpses which begin to decompose and

this has happened before? It might happen again. We may not be the first and we might not be the last. Another piece of evidence is the dinosaurs. Nowhere in the Bible does it mention the dinosaurs (apart from once it says reptiles‚ but this is taken to mean present day reptiles as WE know them; snakes‚ iguanas and alligators etc…) We have fossils as rock solid proof that nobody can argue with‚ which shows that dinosaurs and creatures of that time really did exist. This doesn’t fit in with the religious

In my opinion‚ being human can be summed up into a simple definition—a unique individual. Although we all developed from a similar place‚ being different makes us human. Each one of us has our differences‚ we

I wondered if there is any relation between the two. I learned from a video I watched in science class a lot of scientists believed that life on earth started in the oceanic crust and that actually the human species‚ going back to dinosaurs and reptiles evolved from fish. Studying the ocean have helped scientists learn more about the origin of life and I hope that a program such as MAOS will help me understand more about this topic. I want to also understand how ocean helps keeps our weather cool
