What affect do humans have on speciation?
As part of the environment of other organisms humans can have great effects on speciation. Especially adaptive radiation. As we contribute heavily to the extinction of some species other species flow into those open niches and radiate outwards to possible speciation.
Do birds break down food by chewing it with their teeth?
it is un-certain that birds do chew, their food, but mammals do. But, the next best thing to a vegetarian bird that chew it's food, are the ornithops, a group of plant-eating dinosaurs which includs ceratopsids (triceratops) and the hadrosaurs (duck-billed dinosaurs) sadly like all the other dinosaurs they went extinct 65 million years ago, but it might be possible (atleast possible) if not likely that modern plant-eating birds may chew their food with annomal ridges the the sides of their beacks as they move them up and down while the ridges them selves cut up the vegetation into smaller bits, only to leave the rest grinded up by stones in their stomachs, so that the digestive juices could get back to work. So, like with mammal hervibores, as the bird's stomachs digest, the bird itsealf (the body) will be back in physycle order to their daily eating.
What is most likely to cause a mass extinction?
In order to cause a mass extinction, something has to happen with worldwide (or nearly so) effects. In at least two of the mass extinction events for which we've determined a likely cause, the cause was an astrobleme; an impact of a comet, asteroid or other celestial body with the Earth. In at least one other, the cause appears to have been massive volcanic eruptions, but after that long, we cannot yet determine the cause of the volcanism.
Do people kill rhinos?
It is a sad truth but people still do kill rhinos. The black and white rhino are on the endangered species list. Rhino horns are a prized and expensive commodity in many countries, most of them in Asia. Long believed to help the libido, and to heal certain maladies, the rhino has been hunted into near extinction. Combined with the lack of habitat it is possible that this generation may see the last of the rhinos.
Can you describe condition that makes it possible for a species to undergo adaptive radiation?
When the dinosaurs went extinct the mammals that were living alongside the dinosaurs underwent massive adaptive radiation. Large extinction events can give rise to niche openings for species that go through the extinction event.
How does the theory of asteroid impact relate to the extinction of Dinosaurs?
I does not. The asteroid would of had to knock out the entire earth for that to happen. If you think of the facts it is just not possible.
Could mass extiction have been caused by an asteroid?
It has been speculated that the mass extinction of dinosaurs was caused by an asteriod, however there is not enough evidence collected to support this. It is still argued possible though.
How many years ago was the largest mass extinction?
The most extreme that we are aware of was the Permian Extinction about 252 million years ago, in which 95% of all life was killed. The cause is still unknown, although it is possible that this was an impact event.
Is it possible to download the spore final dinosaurs?
yes, it is possible to download the spore final dinosaurs
The extiction of the dinosaurs made possible the expansion and rise of what other class of animals?
The extiction of the dinosaurs made possible the expansion and rise of mammals.
Which is a possible explanation for mass extinction?
Global whining
Did dinosaurs go inside the earth's core?
No it is not possible.
Can Dinosaurs stay in a reptile house?
Yes it would be possible for dinosaurs to be in a reptile house if they were still alive. I guess the bones could be in a reptile house but no real dinosaurs.
What were the two possible effects of slow climate change on the dinosaurs' habitats?
None. The dinosaurs died a fairly quick death.
Is it possible the asteroid that destroyed the dinosaurs has any connection with the existence of humans?
An asteroid did NOT destroy the dinosaurs. A flood did. Read the Bible. :) The flood was the one who killed the dinosaurs, but Noah took small dinosaurs (e.g lizards, crocodiles).
Is possilbe to broght back the diosners?
No it is not possible to bring back the dinosaurs
