The Extinction Puzzle

It is threatened by habitat loss.

This bird is in danger of dying out.

They are in danger of extinction.

It is threatened by habitat loss.

Some are actually on the brink of extinction.

These animals are on the verge of extinction.

How many languages are in danger of dying?

Some wild animals are on the brink of extinction.

The cause of its extinction is unknown.

We nearly went extinct.

The extinctions still go on.

Shape shifting Dinosaurs The cause of a premature extinction.

Many shark species are threatened with extinction.

Many animal species are on the brink of extinction.

So they're looking at ways to reduce the risk of extinction.

It survived even during the time that the dinosaurs died off.

The danger is not at all unprecedented.

That's a good number to go extinct, I think.

As rocks and mountains die, grains of sand are born.

But does the earth have to wait for our extinction as a species?

The date and cause of extinction for the Mascarene parrot is unclear.

The book's popularity made the dodo a well known icon of extinction.

During the die off of the gharial we did galvanize a lot of action.

Present day extinction rates are 100 1000 times greater than the background rate and up to 30 of current species may be extinct by the mid 21st century.

The beautiful bird is said to be in danger of dying out.

That species of bird is said to be in danger of dying out.

For this reason, some colleagues and I have calculated the rate at which bird species became extinct in the recent past and the rate at which they will likely become extinct in the future.

With the exception of the past five mass extinction events, estimates from the fossil record suggest that an approximate background rate is one extinction per million species years, (1 E MSY).

The extinction rate is 1,000 times higher than normal, and is increasing.

Early European exploration likely continued this rapid pace of extinction.

The title of my talk Shape shifting Dinosaurs The Cause of a Premature Extinction.

At times, however, there are sudden radiations of new species or mass extinctions.

Another keystone species is a famous animal called the European aurochs.

And I'll illustrate that five point framework by the extinction of the Greenland Norse society.

And there'd also be an extinction event like fossils would suddenly disappear.

The danger is not at all unprecedented. Species go extinct all the time.
