Hello!
To answer this question we need to understand what a universal theme is.
A universal theme, is defined as being an idea that can apply to anyone regardless of different context, different backgrounds, different geographic locations and different cultures.
It's a central idea that can be connected to texts in various ways.
This being said, it can argued and said that greed is a universal theme. Because it can apply to anyone and can worded differently depending on context to fit more accurately.
So to sum it up in conclusion, yes, greed is a universal theme.
Hope this helps.
This question is rather vague, but there are many different things you can learn about Earth's history though the study of animals. For example: you can look at the fossils of dinosaurs and learn how they lived, their size, what era they were from, etc. If you are looking at live animals, you can determine how they live with the environment around them.
