Study Notes
- Swedish botanist and physician Carl Linnaeus revolutionized how scientists categorize and name living organisms.
- He devised a uniform, hierarchical taxonomic system still in use.
Milestones
- In 1728, Carl Linnaeus began studying medicine and botany at Uppsala University.
- By 1730, he started lecturing on botany.
- In 1732, Linnaeus traveled to Lapland and northern Sweden.
- During his expedition, he discovered 100 new plant species.
- Linnaeus published Systema Naturae in 1735, which secured his reputation.
- He published Genera Plantarum in 1737.
- In 1738, Linnaeus became a physician.
- By 1742, he became a professor of medicine and botany.
- Linnaeus established binomial names for flora in 1753 (Species Plantarum) and fauna in 1758 (10th ed. Systema).
Early life and education
- Carl Linnaeus was born in a poor area of southern Sweden.
- His father was a curate and amateur botanist.
- Linnaeus showed little interest in formal education or an ecclesiastical career.
- An enduring passion for plants was evident from a young age.
- Linnaeus studied botany and medicine at Uppsala University after completing schooling.
- Due to his extensive knowledge of botany, he lectured at the university 2 years later.
- In 1732, Linnaeus received funding for a research expedition to Lapland.
- The goals were to record information on natural resources and discover new species of plants and animals.
- The expedition inspired him to produce a groundbreaking manuscript.
Categorizing Life
- Linnaeus was frustrated by inconsistent and overcomplicated classification systems.
- Attempts to classify life forms had begun with Aristotle.
- By the18th century no unified system existed.
- Linnaeus formulated a method to categorize species.
- His method simplified and transformed the process.
- In 1735, he published Systema Naturae.
Linnaea borealis
- Linnaeus's favorite plant was Linnaea borealis (twinflower).
- The plant was named after him.
- Its two-part name indicates its genus and species, a division that Linnaeus himself devised.
