@Tiberius So here is a distinct definition of how evolution occurred, and I wonder if and how you agree:
"How Do We Know That Evolution Has Occurred?
The evidence for evolution has primarily come from four sources:
1. the fossil record of change in earlier species
2. the chemical and anatomical similarities of related life forms
3. the geographic distribution of related species
4. the recorded genetic changes in living organisms over many generations"
