Evidence for Evolution - Fossil, Comparative Anatomy - Unsolved Practice Set

Q1. Fossils are considered strong evidence for evolution mainly because they:

1. Show organisms unrelated to modern species
2. Provide a chronological record of gradual changes in organisms over geological time
3. Are always found intact and unchanged
4. Have no connection to living organisms

Q2. Archaeopteryx, an important fossil showing features of both reptiles and birds, is often cited as an example of a:

1. Vestigial organ
2. Connecting/missing link
3. Homologous structure
4. Analogous structure

Q3. The presence of structures like the human appendix or wisdom teeth, which appear to have reduced or lost their original function, are called:

1. Homologous organs
2. Analogous organs
3. Vestigial organs
4. Convergent organs

Q4. Which of the following is considered biogeographical evidence for evolution?

1. The presence of fossils in rock strata
2. The distinct distribution of marsupials mainly in Australia
3. Similarities in bone structure across species
4. DNA sequence similarity

Q5. Early embryonic similarities among vertebrates (such as the presence of gill slits in fish, reptile, and human embryos) are used as evidence from the field of:

1. Comparative anatomy
2. Comparative embryology
3. Palaeontology
4. Biogeography
