Accepted Answer

# Brief Explanations:
1. For question 1a: Based on evolutionary biology, the two closest living relatives of modern humans are the common chimpanzee and bonobo.
2. For question 1b: Key anatomical/behavioral differences are rooted in bipedalism, cognitive traits, and skeletal structure.
3. For question 2: Each corrected statement addresses core evolutionary principles: gradual change, utility of fossil evidence, common ancestry, and the timeline of bipedalism.
# Answer:
1. a. Common Chimpanzee (Pan troglodytes) & Bonobo (Pan paniscus)
   b.
   | Humans: | Closest Relatives: |
   |---|---|
   | - Obligate bipedal locomotion | - Knuckle-walking/quadrupedal locomotion |
   | - Large, globular cranium (large brain size) | - Smaller, elongated cranium |
   | - Reduced facial prognathism, smaller jaws/teeth | - Pronounced facial prognathism, larger jaws/teeth |

2. a. Correct statement: Major evolutionary change results from small, incremental changes that accumulate slowly over long periods of time.
   b. Correct statement: Even though fossil evidence is incomplete, it still provides reliable, critical evidence for understanding evolutionary patterns and relationships.
   c. Correct statement: Modern humans and modern apes share a common extinct ancestor, rather than humans evolving directly from modern apes.
   d. Correct statement: The ability to walk upright on two legs (bipedalism) evolved early in the hominin lineage, millions of years ago.
