Depending on the size of the asteroid and the speed of its collision, millions of tons of dust will explode into the atmosphere and be carried all round the world, blotting out the sun. Without the sun's heat the atmosphere would cool and global warming would slow. If the dust cloud remains for years many species will die. This is one of the theories for the disappearance of the dinosaurs.
How would an adherent to punctuated equilibrium explain the lack of intermediate links in the fossil records?
How can natural selection and isolation and genetic variation result in the development of a new species?
Reproduction is an organism's way of creating a new generation of its species. Reproduction is essential for preserving a species (carrying on with the species), and replenishing the number of organisms in it to compensate for dead organisms. Without reproduction, a species would die out in one generation.
