Why do we classify things?
* Classification provides scientists and students a way to sort and group organisms for easier study.
* There are millions of organisms on the earth! (approximately 1.5 million have been already named)
Organisms are classified by their:
* physical structure (how they look)
* evolutionary relationships
* embryonic similarities (embryos)
* genetic similarities (DNA)
* biochemical similarities
UNITY AND DIVERSITY
All living things carry out the life functions. There are many different types of organisms.
In one classification system, there are 2 main groups. In others, there are 3. In the one used by most of the world's scientists, which we will also use, there are 5 main groups. All living things are placed in one of the five KINGDOMS...which are the most general group. They are then broken down into smaller groups, then smaller groups, then smaller and so on until there is just one... SPECIES is the most specific group...⬆️
