1 Based on current knowledge, organisms are primarily composed of organic matter, but organic matter is only produced by organisms. So how did life originate?
2 Miller's experiment demonstrated that organic compounds can form from simple inorganic substances, but it still cannot explain the origin of life. What other limitations exist?
3 Fossils serve as evidence of evolution, but this is based on certain assumptions. What are these assumptions?
4 Are fossils always the result of the mineralization of an organism's body or remains? Explain.
5 Fossils often lack many intermediate forms when used as evidence for evolution. What might be the reasons for this?
6 How do fossil records provide evidence for evolution?
7 Besides fossils, what other evidence supports evolution?
8 Comparing DNA base sequences is considered the most accurate method for determining relationships between different organisms. Explain why.
9 In reality, even using DNA base sequences, it is impossible to determine relationships between organisms with 100% certainty. Why?
