The discovery of which new fossil hominid led Dr. Wood to re-evaluate his study on human origins?

• A. Australopithecus garhi
• B. Sahelanthropus tchadensis
• C. Homo erectus
• D. Paranthropus boisei

Answer: (A)

Verified step by step guidance

1. Step 1: Begin by understanding the context of the question, which is related to human evolution and the study of fossil hominids. Fossil hominids are ancient species that are part of the evolutionary lineage leading to modern humans.
2. Step 2: Review the significance of each hominid mentioned in the options. For example, Australopithecus garhi is known for its association with early tool use, Sahelanthropus tchadensis is one of the oldest known hominids, Homo erectus is a species with evidence of advanced tool use and migration, and Paranthropus boisei is known for its robust cranial features.
3. Step 3: Consider Dr. Wood's contributions to the study of human origins. Research his work and identify which fossil discovery led him to re-evaluate his perspective on human evolution.
4. Step 4: Analyze the timeline and significance of each fossil discovery to determine which one had a profound impact on Dr. Wood's studies. Focus on the implications of the fossil's features and its placement in the evolutionary tree.
5. Step 5: Conclude by identifying the fossil hominid that aligns with Dr. Wood's re-evaluation of human origins, based on the evidence and context provided in the question.
