McGee's (1991) original explanation represented human geography perspectives.
Each of these seven summated rating scales was measured independently of each other, hence every participant had seven unique scores, one for each type of explanation, representing the extent that explanation was endorsed across the seven evolution scenarios.
This approach then challenges students to gather evidence from the fossil record and analyze that evidence using critical thinking skills to decide for themselves which explanation (or explanations) represents the best answer to the question raised (Lawson, p. 82).
Finally, on the largest and longest scales, predominates, and the patterns relevant to biological explanations represent accumulation and maintenance of genetic diversity.
Ultimately, random chance and our proposed explanations represent testable alternative hypotheses that could and should be directly tested.
Table 4 shows the proportion of all explanations represented by each of the 16 explanatory behaviours, indicated in parentheses, among negligent and non-negligent groups.
"While this evolving explanation may represent an accurate description of the proposed legal structure of the consolidation, it has cast a cloud of vagueness and skepticism over the issue in the public eye," the report concluded.
These results suggest that the learning with the SOC-based explanation promoted representing problems based on their structural features rather than their superficial features (the increase of the time required suggests the subjects of the experimental group inferred the physical structure from surface structure).
A possible explanation is represented by poor hygienic conditions (a couple of workers smoked during work hours), which may lead to hand contamination and Co absorption from routes other than inhalation (dermal and oral).
