- Microevolution vs Macroevolution
The fact that both micro- and macroevolution (including common descent) are supported by overwhelming evidence remains uncontroversial within the scientific community. However, there has been considerable debate over the past 8…

- Macroevolution, which refers to large-scale evolutionary changes over long periods of time, has not been directly observed within the lifetime of a human1. However, patterns of macroevolution, such as adaptive radiations, extinctions, and convergent evolution, can be inferred from the fossil record and comparative studies across different species2.
