Since the time of Linnaeus, the way we classify living things has changed a lot. Here are some important updates:
The Rise of Phylogenetics: Instead of just looking at how organisms look, scientists now study their family ties. They check DNA and genetic information to see which species are more closely related.
Domains Added: Linnaeus sorted living things into two groups: plants and animals. Now, we have three main domains: Archaea, Bacteria, and Eukarya. This helps us understand life better by breaking it down into more specific categories.
More Categories: We still use Linnaeus’s system (Kingdom, Phylum, Class, Order, Family, Genus, Species), but now we often include extra levels, like supergroups or clades. These help us represent how different species are linked through evolution.
DNA Barcoding: This new method uses small bits of genetic material to quickly identify species. It’s super useful for classifying organisms, especially when they look alike.
In simple terms, classifying living things has changed from a straightforward naming system to a more complicated network that shows the amazing history of life on Earth!
