Document Summary
According to evolution, there is no static world; everything in the environment is always changing. Because the environment is changing, the animals and beings in the environment are also changing. Gradual across generations but if generations pass very quickly (e. g. insects like cockroaches that have many generations of change within a few weeks. ) All organisms descended from a single common ancestor. Over time, different species evolved, each adapted to their own ecological niche. The debatable question remains could we have evolved from monkeys? or could all animals, including humans, have evolved from the same protozoa? . Natural selection not only causes changes during changing environments, it also prevents changes in static environments. The environment and change in the environment that fuels evolution. If there is a lot of environmental change then there will be a lot of evolution. If the environment is static (not changing) there will be slow evolution.
