It is common knowledge now that we depend on insects for our continued existence; that, without key pollinators, the human population would collapse in less than a decade.

No one would want to read a book in which I explain the science of cloning because it would be very dull and it would also make no sense.

With the advent of genetic engineering the time required for the evolution of new species may literally collapse.

We're losing biodiversity globally at an alarming rate, and we need a cornucopia of different plants and animals, for the planet's health and our own.

Human cloning is coming.

You look at the fact that for millions of years species on earth have been developing and we've been knocking them off at like a hundred a day.

As in all of biology, comparative studies showing differences among species are often helpful for a better understanding of the basic mechanisms; with all its advantages, there is a danger of clinging exclusively to one model organism.

When a parasite moves to a new habitat, it can find new hosts through a process called the trans-species jump. Often, the new host has no resistance; it and the parasite haven't had time to adjust to each other through natural selection (it is frequently not in the best interest of a parasite to kill its host quickly).
