How much longer can we live on Earth?
This is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet’s habitability.
Why are there still apes if we evolved?
We didn’t evolve from apes; rather, apes and humans evolved from a common ancestor. Natural selection doesn’t care about whether a species is smarter or more progressive. … Thus, the reason that modern apes are still around is that they have been successful at surviving in their environment.
Can humans evolve to breathe underwater?
Virtually impossible. Given the mammals that already live in the water have never evolved traits to breath underwater, it suggests that land-based organisms that revert to water-living do not gain gills. For humans there is zero selection pressure to breath underwater, so there’s no basis for acquiring such a trait.
Are humans the apex predators?
Predators that exert a top-down control on organisms in their community are often considered keystone species. Humans are not considered apex predators because their diets are typically diverse, although human trophic levels increase with consumption of meat.
