Verified step by step guidance1
Understand the context: Linnaeus's taxonomy was a system of classification that grouped organisms based on shared characteristics. It was groundbreaking for its time but also reflected the biases and limitations of 18th-century science.
Recognize the controversial aspect: Linnaeus classified humans into subspecies based on geographic location and perceived physical differences, which introduced subjective and culturally biased categorizations.
Clarify why this was controversial: This classification implied a hierarchy among human groups, which was not scientifically valid and contributed to the justification of racial biases and discrimination.
Compare with other options: Linnaeus did not exclude humans from the animal kingdom; he placed humans in the same kingdom as other animals (Animalia). He also did not use molecular data, as this was not available during his time, nor did he place humans in a separate kingdom.
Conclude the reasoning: The correct answer is that Linnaeus's classification of humans into subspecies based on geographic and perceived physical differences was the most controversial aspect of his taxonomy.
