Will we ever be able to bring back extinct animals?
But the very idea of de-extinction is somewhat misleading: Scientists say it’s not possible to really bring back an extinct species. Instead, scientists are planning to genetically modify an elephant to create a new synthetic organism resembling a woolly mammoth.
What killed the megafauna?

What kind of a shark is a Hemi?

Why is it important to make sure animals don’t go extinct?
Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.

Is extinction a natural selection?
The extinction of species (and larger groups) is closely tied to the process of natural selection and is thus a major component of progressive evolution. In some passages of the Origin, Darwin seems to have seen extinction as part of natural selection; in others, as an inevitable outcome.
Why is the current extinction rate so high?
The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
Why do animals become extinct and endangered?
The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
Is dark matter cold matter?
The standard model for dark matter is that it is ‘cold,’ meaning that the particles move slowly compared to the speed of light, Fassnacht said. This is also tied to the mass of dark matter particles. The lower the mass of the particle, the ‘warmer’ it is and the faster it will move.
