Biology Practice: Human Evolution (Mock Test 4 - Expert: Experimental Evidence & Logical Data)
1. In an experiment, a scientist removes the tails of mice for 50 generations. According to "Expert" biological laws, why do the offspring in the 51st generation still have full-length tails?
2. Analysis of DNA sequences shows that humans and Chimpanzees share approximately 98% of their genetic material. This data logically concludes:
3. Expert Logic: Why are the "Wings of a Bat" and "Forelimbs of a Horse" considered homologous, while "Wings of a Butterfly" and "Wings of a Bird" are analogous?
4. Which experimental setup proved that organic molecules could be synthesized from inorganic gases (Chemical Evolution)?
5. Clinical Correlation: A human baby born with a short, functional tail is a rare medical case that provides evidence for:
6. If we compare the embryos of a fish, a bird, and a human at early stages, they look nearly identical. This data supports the theory of:
7. Data Set: Fossil A is found in the deepest rock layer, and Fossil B is found in a layer near the surface. Logically, which is older?
8. Why is "Homo erectus" considered a major turning point in human evolution based on archaeological data?
9. Logical Inference: Why did bipedalism (walking on two legs) likely evolve in early hominids?
10. "Genetic Drift" is an expert concept explaining that gene frequencies can change due to:
11. Carbon-14 dating is a method used by palaeontologists to determine:
12. The presence of 'Gill slits' in the embryonic stage of all vertebrates is an expert proof that:
13. Expert Observation: A flightless bird like the Ostrich has wings but cannot fly. Logically, these wings are:
14. What is the logical difference between 'Microevolution' and 'Macroevolution'?
15. Why did "Australopithecus" have a smaller brain than "Homo erectus"? (Biological Data)
16. If a population is geographically isolated by a mountain range, it logically leads to:
17. Data Analysis: $Archaeopteryx$ has teeth and a long bony tail (reptilian) but also feathers and a wishbone (avian). It is a:
18. Why do experts say "Evolution is not progress towards a goal"?
19. In Darwin's theory, the "Unit of Selection" is the ________, while the "Unit of Evolution" is the ________.
20. The logical outcome of 'Divergent Evolution' is that related species:
