Can humans survive mass extinction?
First, mass extinction events are not one-day cricket matches that are gradual processes which happen over a long period of time. … The pre-Cambrian mass extinction wiped out nearly 95% of marine species. So there is a small probability that humans will survive the catastrophe.
What will cause human extinction?
Anthropogenic human extinction is sometimes called omnicide. Many possible scenarios of anthropogenic extinction have been proposed, such as climate change, global nuclear annihilation, biological warfare and ecological collapse.
How long are humans meant to live?

How old is the first human?
Scientists have unearthed the jawbone of what they claim is one of the very first humans. The 2.8 million-year-old specimen is 400,000 years older than researchers thought that our kind first emerged.
How long did humans live 5000 years ago?
Lasting roughly 2.5 million years, the Stone Age ended around 5,000 years ago when humans in the Near East began working with metal and making tools and weapons from bronze.

What would happen to Earth without humans?
From interviews with members of the Wildlife Conservation Society and the New York Botanical Gardens Weisman predicts that native vegetation would return, spreading from parks and out-surviving invasive species. Without humans to provide food and warmth, rats and cockroaches would die off.
Are humans still evolving?
“It’s a game-changer in terms of understanding evolution.” … Evolutionary biologists have long concentrated on the role of new mutations in generating new traits. But once a new mutation has arisen, it must spread through a population.
