You get to learn about the classification of living things, from Linnaeuss system to modern phylogenetics. Practice your skills building and using dichotomous keys while working with different groups of plants and animals, then test your skills while classifying bacteria in a virtual microbiology lab.
After completing this tutorial, you will be able to complete the following:
How did Linnaeus classify organisms?
~ Linnaeus devised a system of classification that grouped organisms together based on similar physical properties.
How do today's scientists classify organisms?
~ Modern scientists classify organisms according to their evolutionary relationships. In other words, organisms that share characteristics with more recent common ancestors are grouped together.
What are the four main criteria used for classification?
~ The four main criteria used for classification include physical properties, embryological properties, physiological properties, and genetic similarities.
What is the difference between analogous and homologous organs?
~ Analogous organs have similar functions, but different physiologies and evolutionary origins. Homologous organs may have different functions, but they have the same evolutionary origins.
