Questions and Answers

How did Gaspard Bauchin's work directly influence the development of Linnaeus's taxonomic system?

Bauchin's practice of cataloging plants by genus and species provided a direct model for Linnaeus's binomial nomenclature system. (correct)
Bauchin's extensive work on medicinal plants gave Linnaeus insights into the pharmacological properties of different species, influencing his classification criteria.
Bauchin's research in anatomy provided a foundation for Linnaeus's understanding of animal physiology, leading to a more accurate classification system.
Bauchin's detailed illustrations of plant species inspired Linnaeus to include visual aids in his *Systema Naturae*, making it more accessible.

Why is Carl Linnaeus considered the 'father of taxonomy' despite not creating the first system for classifying organisms?

Linnaeus's hierarchical system, while improved upon, remains the fundamental structure used today; while those before him do not. (correct)
Linnaeus's system was the most complex and had the most number of categories compared to other systems.
Linnaeus developed the very first system of classifying organisms and nobody had done it before.
Linnaeus's system was purely original and did not build upon the work of any other scientists who came before him.

What does the quote, 'Nature does not proceed in leaps and bounds,' suggest about Linnaeus's view on biological classification?

Linnaeus saw clear, discrete boundaries between species, with no transitional forms.
Linnaeus thought organisms arose spontaneously and independently.
Linnaeus believed that evolutionary change occurs rapidly through punctuated equilibrium.
Linnaeus viewed the natural world as a continuum with gradual transitions between organisms. (correct)

In what way did the publication of Species Plantarum (1753) and the 10th edition of Systema Naturae (1758) revolutionize the field of biological taxonomy?
