Early classification was based on physical features. Species with similar characteristics were grouped together under 2 kingdoms: animalia and plantae.
What was early classification based on?
What two things did Swedish biologist Carl Linnaeus create...
Microscopes improved so scientists could see inside cells. DNA was discovered and scientists began to analyze DNA from different species.
Today we classify species based on shared ancestry which is determined by a range of evidence including DNA analysis, comparison of bio -chemical processes, and more.
Make a list of some things that you notice from this graphic. Choose meaningful things that you see and write them down and what they mean.
Example: I see that the Domain has the largest portion of the inverted pyramid. I think this means that in that portion there are more organisms that share that domain.

This is the most recent and highest level of classification. Work by the American scientist Carl Woese and his team led to this taxon being added in 1990. There are three domains.
Unicellular with no nucleus or membrane-bound organelles. Has a cell wall. Some are harmful and some are useful.
Unicellular with no nucleus or membrane-bound organelles. Has a different type of cell wall. Some of them live under extreme conditions, e.g. hydrothermal vents
A mix of unicellular and multi-cellular organisms. They always have a nucleus. Some eukarya have cell walls like plants and fungi, but animals do not.
Which domain have organisms that contain cell walls?
(Select all that apply)
All of these 4 kingdoms are apart of the domain eukarya. What do all of these kingdoms have in common?
