Here's the evolutionary process. We started off as bacteria ( some say from meteors) which then kept on adapting and changing in the water to fish. These fish became frogs (but thats reptile evolution). Anyway, we stayed fish until around the jurassic when we were whales. we eventually crayled onto land into something like a tiger, then we got smaller like rats. Dinosaurs went extinct but we were too small to be effected, so we then started getting bigger again. we became monkeys. these monkeys lived dominantly in Africa and Europe. the europeans were too stupid to evolve and died out, but the africans got smarter, invented fire and eventually became us.
What else can I help you with?
What was the biggest change in the earths atmosphere between the precambrian and the paleozoic eras?
The origin of free oxygen
How would your understanding of earths past change if a scientist discovered a mammal fossil from the paleozoic Era?
Finding a Paleozoic fossil would change our thinking completely, we would have to rethink the entire evolution of animals and the conditions on Earth all the way back to and including the Paleozoic. That is 500 million years of geologic history to rewrite.

During the devonian time period most of land was under water.

What caused a major change in the composition of Earths atmosphere?
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.
What percentage of earths water is fresh water available for use by living organisms?
three percent of all the earths water is fresh water

How much do humans currently consume of the available food crops and medicine produced by earths organisms causeing a potential threat to biodiversity?
Humans currently consume a great amount of the available food crops and medicine produced by earths organisms. This is a threat because some of these organisms are rare.
