Final answer:
Linnaeus' taxonomy was based on physical traits, but modern taxonomy also includes genetic information. Modern taxonomy is updated to accommodate new discoveries, unlike the fixed Linnaean system.
Step-by-step explanation:
Two differences between Linnaeus' use of taxonomy and modern biologists' use of taxonomy are as follows:
- Classification Basis: Linnaeus classified organisms primarily based on physical and morphological traits, while modern taxonomy also considers biochemical and genetic similarities and differences.
- Dynamic Nature of Taxonomic Systems: The Linnaean system, developed in the 1700s, has undergone revisions due to new species discoveries and advances in science. Modern taxonomy is continually updated to reflect these changes, indicating a more fluid and comprehensive system.
In conclusion, while Linnaeus introduced the binomial naming system for consistency across scientific communities, current taxonomic practices have evolved to include genetic information and a constant refining process to accommodate new findings.
