Geographic Strata & Tectonic Plates / Continental Drift 

# data[].attributes.body
The movement of the tectonic plates caused by the movement of continental land masses and the organisms that are living or inhabiting this land had to adapt and evolve to new living conditions. Fossils are found on continents are the same animals at the same period in geologic history yet separated by an ocean. Further proof of evolution.

Mitochondrial DNA is passed down from the mother because only the mother carries this mtDNA. Mutations do occur but not often, actually it's less frequent than 1%, which allows geneticists to trace ancestry back to certain lineages and human origin locations. This mtDNA showed us human origins where in Africa, added to fossil evidence, it shows proof of evolution.

Observed Evolutionary Changes & Adaptation 

# data[].attributes.body
As time carried on we could see changes in many species which have similarities showing common ancestors and has some variations showing evolution and how animals have to adapt and genetically mutate to fill ecological niches.

# data[].attributes.body
Fossils have been found on continents sperated by oceans so this is evidence for geological time and since they all fit together is also supports continental drift and shows evolution.

Homologous Structures in comparative anatomy

As we are aware homo means same so homologous bones means that the structure shows genetic similarities meaning we have a common ancestor like having the same bones but with different functions.

Due to endosymbiosis happening with bacteria in early cells, it later became a nucleus and cell organelles so all in all a prokaryote becomes a eukaryote.
