How Are Organisms Classified? | Evolution | Biology | FuseSchool

In terms of biological classification, organisms are classified, or grouped, with other organisms that they are most closely related to.

These small groups are then classified together into larger groups and so on, until we reach the top level of classification which places organisms in one of three biological domains - Archaea, Bacteria and Eukarya.

When each organism is classified in this way it allows scientists to see the relationships between different species, and make sense of the hugely diverse array of life.

Classifying of anything means to put it into a group. In terms of biological classification, organisms are classified, or grouped, with other organisms that they are most closely related to.
These small groups are then classified together into larger groups and so on, until we reach the top level of classification which places organisms in one of three biological domains - Archaea, Bacteria and Eukarya.
When each organism is classified in this way it allows scientists to see the relationships between different species, and make sense of the hugely diverse array of life.
Modern system of biological classification or taxonomy are based on the work of a pioneering eighteenth-century scientist called Carl Linnaeus by studying hundreds of organisms Linnaeus devised a method of grouping them according to their shared physical features those with similar physical features could be classified together the most similar organisms ie those that could breed and produce fertile offspring were designated as belonging to the same species and given a Latin species named accordingly.
For example all domestic dog breeds belong to the same species called Canis lupus familiaris? Others members of the dog family that are closely related but not the same species will share the higher group name the genus name but have a different species name, for example the grey wolf which is the closest relative to domestic dog is classified as Canis lupus lupus.
By this system we can classify organisms according to their evolutionary history. The layest also created higher and more inclusive taxonomic categories that encompass an increasingly broader range of organisms. The structure of Linnaeus's taxonomic groups can be seen here. You can make up a little rhyme or acronym to remember this. Such as keep ponds clean (kpc) or frogs get sick. By using this system of common groupings we can develop diagrams that showed the interrelatedness of organisms based on the morphological diversity. For example this diagram of a taxonomic tree shows that humans are more closely related to chimpanzee s than they are to gorillas. A common ancestor is represented by each split in the branches of the taxonomic tree.
How long ago did humans and gorillas diverged from an evolutionary perspective.
Recept advances in science including the ability to categorize DNA sequence have enabled scientists to accurately determine how closely species are related to each other. This has led to the revision of the original grouping suggested by Linnaeus. New organisms are constantly being discovered. And relationships between organisms are changing all the time. So the importance of a taxonomic study to modern science can not be understimated.

the video is amazing but plz consider the narrators voice to be changed as it is less clear

[NElectronicSoul]

This like the rest of the videos in the series is amazingly animated and clear however the narrators voice and the language used is ridiculously unsuited for it's target audience of young children. Please consider rerecording using a more neutral voice and less verbose language in order to make it truly accessible for all.

Home school is why I have to watch this

[rohaberhane]

carl linneus classified living things into the 5 kingdoms. Carl woese came up with the three domain groups of eucaryota, bacteria and archea

[randomthings]

I had to watch this in since allmost died

[HxrryTv.]

Great vid about biology - OPGS student

[tiktokvsrobloxvideo]

anyone else here because online school?

[jenniferrodrigo]

At what age do you study this. At college is it?

my mom likes those videos because she want me to be educated but i like it
