What happened as a result of an asteroid collision on the Yucatan peninsula 65 million years ago?
It is widely believed that that is the event that caused the extinction of the dinosaurs as well as many other lifeforms on Earth.
What ended the Jurassic period?
The end of the Silurian period and the beginning of the Devonian period was not defined by an extinction event, but by the distinctive rock formations of the period. As a result the end of the Silurian period is uncertain by +/- 2.8 million years.
What is biological hot spot?
biological hot spot is a place where significant numbers of habitats and species are in immediate danger of extinction as a result of human activity
What was the positive result of the dinosaur extinction?
The extinction of the dinosaurs is one of the many events that allowed humans to evolve. After the dinosaurs died out, mammals began to occupy the world they left behind. Mammals grew and diversified, spreading throughout the Earth, and eventually giving rise to humans.
Is the male human semen carcinogenic?
No. That would be a trait that would result in extinction of the human race, since ever woman that has ever given birth has been exposed to semen.
How long ago did trex live?
Tyrannosaurus rex lived during the end of the Maastrichtian stage of the Cretaceous period. That was about 68 to 65.5 million years ago. They died out as a result of the K-T extinction event.
What made the cretaceous period end?
The Cretaceous period ended as the result of a mass extinction event, probably resulting from an asteroid impact. This wiped out 65 percent of life on earth, including the ammonites, the plesiosaurs, the pterosaurs, and, most famously, the dinosaurs.
What evidence suggests that a mass extinction of the dinosaurs occurred at the end of the cretaceous?
The Cretaceous period ended as the result of a mass extinction event, probably resulting from an asteroid impact. This wiped out 65 percent of life on earth, including the ammonites, the plesiosaurs, the pterosaurs, and, most famously, the dinosaurs.
What is the result of the death of the last member of a species?
= extinction
What period of time did ammonites live in?
Devonian to cretaceous is the the geological age of ammonoids They first appeared during the Devonian Period (approximately 410 million years ago). They almost died out at the end of the Permian Period (251 million years ago), and again at the end of the Triassic Period (205 million years ago). They finally became extinct at the end of the Cretaceous Period (65 million years ago), perhaps as a result of a lowering of ocean levels.
How mass extinction affected life on Earth?
Mass extinction isn't a natural role in any life-system. They happen as a consequence of some catatrosphic disaster or radical unbalance in the eco-system. As a result of mass extinctions other 'groups' evolve into species that take the place of those exterminated.
What ended the Cretaceous Period?
The mass extinction of the dinosaurs occured at the end of the Cretaceous Period. There are many theories as to why this happened. Some say a volcanic eruption caused it or a falling meteorite.
What cannot be the result of punctuated equilibrium?
extinction and coevolution
Extinction is the result of a failure to do what?
a failure to continue living
Widespread hunting predators may result in what?
It may result to the extinction of our wildlife animals.
What happened as a result of an asteroid collision on the Yucatan peninsula 65 million years ago?
It is widely believed that that is the event that caused the extinction of the dinosaurs as well as many other lifeforms on Earth.
What is the result of direct competition in nature?
Extinction of the loosing species
