The question was: How did early civilations explain biological diversity?

The answer is: Early philosophers believed that the huge variety of different organisms that exist on earth were created by a supreme being (i.e. a GOD) and that they were immutable (they could not change).

Hierarchies Of Organisation== Organisms have the following levels of organisation 1. Atoms Atoms make everything on earth and maybe everything in the universe. Such as a carbon atom (humans are a carbon based life form) 2. Molecules Molecules are what atoms make. Multiple atoms bond to make molecules but are different from compounds because molecules can be made from two or more atoms where compounds can only be made using two or more different elements. Hydrogen and oxygen atoms make H2O (Water) 3. Cells Cells are the basic building blocks of organisms. For example an animal cell or a plant cell. 4. Tissues Cells make tissues which in turn make organs. For Example Pseudounipolar cells 5. Organ An organ is a bunch of tissues working together like the stomach which is a lining of tissues which work together. Stomach 6. Organ Systems a system for example the digestive system is a bunch of organs working together.

Adaptations 1. Give an example of an adaptation and how it helps an animal (and it's species) survive 2. Give 3 examples of: a) structural adaptations b) behavioural adaptations 3. Jack Rabbits, Bilbys and Fennec Foxes all live in desert environments, Find a Picture of each. What structural feature do they obviously share and how does this adatation help them to survive in their desert habitats
