why the dodo bird become extinct? Over-harvesting of the birds, combined with habitat loss and a losing competition with the newly introduced animals, was too much for the dodos to survive. The last dodo was killed in 1681, and the species was lost forever to extinction.
How does speciation cause extinction? How does speciation cause extinction? Many of the traits associated with elevated rates of speciation, including niche specialization and having small and isolated populations, are similarly linked with an elevated risk of extinction. This suggests that rapidly speciating lineages may also be more extinction prone.
What is extinction and how does it affect speciation? “If they die out or mix with other groups before they become separate species, there will be no speciation,” says Mats Dynesius, Associate Professor at the Department of Ecology and Environmental Science. “The risk that they do not survive long enough as separate groups is generally large, but varies among groups.
How mass extinction plays an important role in speciation? At the most basic level, mass extinctions reduce diversity by killing off specific lineages, and with them, any descendent species they might have given rise to. In this way, mass extinction prunes whole branches off the tree of life.

did native americans hunt buffalo to extinction?

Lava flow twice the size of Europe covered Siberia 250 million years ago. We knew it was big – but not this big. Geologists now suspect the massive eruption of lava in Siberia 250 million years ago was at least twice as large as they’d thought.
are invasive species a major cause of extinction?
The link between species invasions and the extinction of natives is widely accepted by scientists as well as conservationists, but available data supporting invasion as a cause of extinctions are, in many cases, anecdotal, speculative and based upon limited observation.
how could the human race become extinct?
Human extinction is the hypothetical end of the human species due to either natural causes such as population decline due to sub-replacement fertility, an asteroid impact or large-scale volcanism, or anthropogenic (human) causes, also known as omnicide.

Instead, climate change was found to typically lead to local extinctions and declines by influencing interactions between species, such as reducing prey populations for predators.
Why are ants going extinct?
Overexploitation and pollution are the main factors that result in ant extinction. Ants are vital to the smooth functioning of our ecosystem. A sudden decline in ant population will immediately disrupt the food pyramid. We as individuals should understand the value of ants and not endanger them.
Is the Spix’s macaw extinct?

Will hippos ever go extinct?

Why are hippos important?
The hippopotamus is an animal very important to the health of Africa’s rivers and lakes. Their dung, or solid waste, helps Africa’s aquatic ecosystem. But researchers warn that hippo populations are decreasing. They say that could damage ecosystems.
Can I transfer my ark character to another server?
You can move your player character, items, and dinosaurs from one ARK server to another. While there are limits on which servers you can transfer between, they’re relatively generous, and you can move a lot of items and creatures between compatible servers.
What type of evidence is used to identify extinction events?
Marine fossils are mostly used to measure extinction rates because of their superior fossil record and stratigraphic range compared to land animals.

Polynesians arrived sometime before 1300, and all moa genera were soon driven to extinction by hunting and, to a lesser extent, by habitat reduction due to forest clearance. By 1445, all moa had become extinct, along with Haast’s eagle, which had relied on them for food.
