Does Microevolution Make Perfect Sense?

Microevolution is basically as evolution within a species. This happens with minute changes that do not create new species. Almost like a better improved species. Unlike microevolution, macroevolution creates hole new species all together. Experiments can only really test microevolution because of the time limit. If macroevolution is almost impossible observed because of the time it takes. New genes are not required for macroevolution as long as such evolution is limited to closely related species, an example would be lions and tigers. In this instance, the processes behind microevolution and macroevolution are the same and extending microevolution to explain macroevolution makes perfect sense.

In microevolutionary a good example is House
