Study Notes
Effects of Mutations on Somatic Genes
- A mutation on a somatic (body) gene affects only the individual cell or tissue where the mutation occurred, and is not passed on to the next generation.
Consequences of Mutations
- Mutations generally produce abnormal or altered proteins, which can disrupt normal cellular function, leading to disease or abnormalities.
Hugo de Vries' Mistake
- Hugo de Vries mistakenly thought he had discovered the concept of "mutation" as a sudden, drastic change in a species, which he believed was the driving force behind evolution.
Embryonic Development
Correlation between Human and Vertebrate Embryos
- The development of the human embryo shows a strong correlation with the development of other vertebrates (animals with backbones), such as chickens, frogs, and fish, with similar embryonic stages and structures.
Similarity in Embryos of Different Species
- The similarity in embryos of different species reveals a common ancestry and shared evolutionary history, as these similarities are not present in adult forms of the same species.
