What's the difference between macro-evolution and micro-evolution?
Micro evolution also called adaptive evolutions can be observed.
There are many classic examples of micro evolution.
The pepper moths of England are one of the most famous. The white variety of the moth predominated before the industrial revolution. The dark variety predominated during the industrial revolution. When the pollution was cleaned up the white again predominated. These were changes within to aa species micro evolution.
Macro evolution is the unobserved change from one type of species another type of species. An example would be the proposed change from amphibians to reptiles. The theory of macro evolution is an extrapolation from observed micro evolution and fossil evidence. There is no direct evidence for macro evolution, it remains a an unproven theory.
