Multicellular life evolved over a billion years later and it’s only in the last 570 million years that the kind of life forms we are familiar with began to evolve‚ starting with arthropods‚ followed by fish 530 million years ago (Ma)‚ land plants 475Ma and forests 385Ma. Mammals didn’t evolve until 200Ma and our own species‚ Homo sapiens‚ only 200‚000 years ago. So humans have been around for a mere 0.004% of the Earth’s history.

wonder how they did it. History today‚ proves that it wasn’t the organisms themselves that inspired the change‚ but a series of multiple mass extinctions over time. Because of the extinctions‚ adaptations appeared‚ more need to evolve became apparent‚ and made it easier to evolve via the climate and environment.
