Hominids with the same anatomy as modern humans first appear in the fossil records about 200,000 years ago. They existed alongside earlier species that became extinct, as well as with the separate Neanderthals, with whom some interbreeding may have occurred.
Humans make up less than 1 of all mammal species on Earth.
The first humans were likely dark-skinned, but the specific skin color of the very first humans is not definitively known.
Life first appeared on Earth around 3.5 billion years ago through a process called abiogenesis, where simple organic molecules combined to form more complex molecules that eventually led to the development of living organisms.
Scientists believe that the first living cells on Earth were likely anaerobic heterotrophs because early Earth lacked oxygen, and these organisms do not require oxygen for their metabolism. Anaerobic heterotrophs can obtain the carbon compounds they need for energy from organic molecules in their environment, making them well-suited for the conditions of early Earth.
Humans are not a virus on Earth. While humans have had a significant impact on the planet's ecosystems, including pollution and habitat destruction, we are a species capable of positive contributions and stewardship of the environment. It is important for us to find a balance that ensures the well-being of both humanity and the Earth.
