Which of the following is the relatively most accurate method for dating of fossils ?
- Potassium - argon method
- Uranium- lead method
- Electron - spin resonance method
- Radio - carbon method
The Correct Option is C
Solution and Explanation
Electron Spin Resonance Dating finds applications in various fields, including radiation science, organic chemistry, geology, archaeology, and anthropology. ESR dating is preferred over Radiocarbon dating for dating recently formed materials.
So, the correct option is (C): Electron - spin resonance method

Evidence for Evolution
Evolution evidence is one of the most important pillars of current biological theory. It is the only way to prove all of the proposed evolution theories. Fossils, comparative anatomy, and embryo development patterns are among the evidence used to support biological evolution.
Fossils are the non-degraded remains of living organisms discovered within rocks. The age of the fossil is determined by the layer in which it was recovered. In comparison to the fossils found in the upper layers, those found farther down are older. They provide insight on the condition of the specific region. Palaeontology is the scientific study of fossils.
Comparative Anatomy describes how many organisms share an origin and how natural selection or genetic drift led to the evolution of many diverse organisms. There were two categories of comparative anatomy found: homologous organs and analogous organs.
In Embryonic Development, until a certain stage of gestation, the embryos of various species have a similar structure. Human embryos, pig embryos, reptile embryos, and bird embryos, for instance, have similar embryonic development. As they grow older, they transform into the appropriate species. This demonstrates common ancestry once again.
