what was the likely cause of the permian mass extinction? Warming of the Earth’s climate and associated changes to oceans were the most likely causes of the extinctions. At the end of the Permian Period volcanic activity on a massive scale in what is now Siberia led to a huge outpouring of lava.
What caused the Quaternary extinction event? Abstract. The late Quaternary megafauna extinction was a severe global-scale event. Two factors, climate change and modern humans, have received broad support as the primary drivers, but their absolute and relative importance remains controversial.
What are examples of cultural assimilation? Cultural assimilation often occurs with regards to how people dress. A woman from the United States or Western Europe who moves to or visits a country where it traditional for women to wear head coverings may adapt to that cultural norm for dress in setting where it would be expected or appropriate.
How does assimilation affect culture? In this view of assimilation, over time, immigrant communities shed the culture that is embedded in the language, values, rituals, laws, and perhaps even religion of their homeland so that there is no discernible cultural difference between them and other members of the host society.

: the angle through which a crystal is revolved from a definite line (such as that of the crystallographic axis) to the plane of maximum extinction.
will salmon go extinct?
No, salmon are not endangered worldwide. For example, most populations in Alaska are healthy. Some populations in the Pacific Northwest are much healthier than others.
when did the comb jellyfish go extinct?

how did cavemen become extinct?
Scientists broadly agree that the Neanderthals died out about 40,000 years ago, after a wave of modern humans migrated out of Africa about 20,000 years earlier. What remains unclear is why the Neanderthals died out and what role, if any, our ancestors had in the act.
why are polar bears becoming extinct?

Do terror birds still exist?
Phorusrhacids, colloquially known as terror birds, are an extinct clade of large carnivorous flightless birds that were one of the largest species of apex predators in South America during the Cenozoic era; their conventionally accepted temporal range covers from 62 to 1.8 million years (Ma) ago.
Can the sixth mass extinction be stopped?
The good news is that we can stop this mass extinction. While there’s no way to deflect an unforeseen asteroid strike or put a plug in a volcanic eruption, the current extinction rate is being pushed ever higher by human activity — and that means that human activity can also reverse this trend.
Do dinosaurs and birds share a common ancestor?
Scientists have discovered that the tissues used to produce scales in reptiles are similar to those that produce feathers in birds. This suggests that there is a common ancestor between dinosaurs, birds, and reptiles.
What happened to the rest of the human species?
By 10,000 years ago, they were all gone. The disappearance of these other species resembles a mass extinction. But there’s no obvious environmental catastrophe – volcanic eruptions, climate change, asteroid impact – driving it.
When did animals start going Endangered?
