Why is it difficult to prove that evolution happens?
Proving that evolution happens can be challenging for a few reasons. Firstly, evolution occurs over long periods of time, making direct observation difficult. Additionally, the process of evolution involves gradual changes in populations, which can be difficult to track and measure. Lastly, the evidence for evolution is primarily based on indirect observations, such as fossil records and genetic analysis, which some skeptics may question.
What evidence is there to evolution?
The evidence for evolution is extensive and multi-layered, too much for me to cover comprehensively. The Wikipedia article 'Evidence of common descent' has many subcategories. these are: Evidence from genetics Evidence from palaeontology Evidence from comparative anatomy Evidence from geographical distribution Evidence from comparative physiology and biochemistry Evidence from antibiotic and pesticide resistance Evidence from complex iteration Evidence from observed speciation and adaptation Evidence from intraspecies modifications I would recommend the Wikipeidia article and I am sure there are a large number of YouTube videos dedicated to the subject.
