difference between Micro and macro evolution

[Aegrus]

so basicly its all the same thing but on different time scale?

Not really. Micro-evolution is how a species adapts to changing conditions on a season per season basis. Macro-evolution is change deemed so necessary for the survival of a species that such change continues throughout the subsequent generations of that species.

For example, there are two types of moths in a species...one is darker and one is lighter. In years with high pollution, the white moth is more prone to be eaten by predators and the other moth of the same species succeeds. The next year, there is less pollution and the white moth is less prone to predators.

In macro-evolution, take the example of the proto-dolphins living 50-60 million years ago. There was a plethora of fish in the sea. Over-time, the members of the species more adapted to hunting in the sea passed on their genes to the next generation because of survival of the fittest. Over millions of years of this genetic testing by nature, we have the modern dolphin.

. . .Dolphins didn't evolve from fish. Dolphins are mammals. They evolved from whales, which in turn evolved from hoofed mammals or some sort. I don't particularly feel like looking up the scientific names for them right now.

They looked like ugly wolves is as much as I can remember, but all I saw was the fossil. Might be the Pakicetids.
