Molecular biology helps us understand evolution by showing how different species are genetically similar. Here are some important points:
DNA Similarity: Did you know that humans share about 98.8% of their DNA with chimpanzees? This shows that we are closely related in the evolutionary tree.
Genetic Mutations: Over time, species can develop changes in their DNA, known as mutations. For example, humans get about one mutation for every million base pairs of DNA.
Proteins and Amino Acids: The building blocks of proteins, called amino acids, are very similar across species. For instance, a protein called cytochrome c is exactly the same in both humans and chimpanzees.
This genetic information works together with fossils and how we study the body structures of different species. All of this helps us better understand how evolution happens.
