Fossils analysis
Fossils are the rest of living and non living things that existed long ago . Within them we take the rest living and test them in laboratory , not labs , observation also can be done . After testing , we compare depending on what we want to know . In laboratory we can test DNA , number of chromosomes etc . in recent years , this has been done . Fossils have contributed much in evolution reality , and now are still at the top of evolution evidences .
