LIONS can make more lionsSlide37
TIGERS can make more tigersSlide38
BUT ALL LIGERS ARE STERILE. They cannot make more ligers.Slide39
BUT ALL LIGERS ARE STERILE. They cannot make more ligers.
NOT A SPECIES!Slide40
A successful “species” must be able to mate and produce more members of the same species.
Not when a horse and
donkey make
a
sterile
mule…Slide41
If a living species cannot adapt to new ENVIRONMENTAL challenges, the entire species can DISAPPEAR.Slide42

Of all the species that have been on earth. How many are still here today?Slide45
Of all species that have existed on Earth, 99.9 percent are now extinct.

Of all species that have existed on Earth, 99.9 percent are now extinct.
Many of them perished in five cataclysmic events.
According
to a recent poll, seven out of ten biologists think we are currently in the throes of a sixth mass extinction. Some say it could wipe out as many as 90 percent of all species living today. Other scientists dispute such dire projections.Slide51
EXTINCTIONS are COMMON in species.
What are the odds that HUMANS will be here
200 million years from now
?????Slide52
But, not all is lost!!!!Slide53
EXTINCTION does NOT ALWAYS mean an entire SPECIES DIES…Slide54

RATHER THAN DISAPPEAR, SOME SMALLER DINOSAUR SPECIES ACTUALLY THRIVED OVER MANY GENERATIONS WITH MORE FEATHERS, BEING MORE LIGHTWEIGHT AND EAT ANYTHING AVAILABLE.Slide67
So, those smaller omnivore dinosaurs which slowly adapted over many generations into feathery flying creatures were no longer dinosaurs, they actually CHANGED into another species!Slide68
Sometimes when a SPECIES becomes EXTINCT…it actually
slowly
EVOLVED
into another species!Slide69
Loss of polar bear habitat has forced polar bears to get closer to grizzly bears in Canada.Slide70
These baby “grolar bears” are probably sterile, but if someday, a few are NOT, then a new species of bear is made!Slide71

Most of the time, we just have normal, smooth, gradual evolution with background extinctions.
