guess I don't understand what "A" is saying what does "animals that lived relatively soon after the first" mean ? I don't see how this statement has anything to do with the stem. Honghu/Anand cud u explain ?
I couldn't make sense out of A either that's why i didn't even try to analyze it.
A says that we have fossils of land animal X(say cow) just after land animals emerged on land(say 1600 million years ago).
This initial fossil(of cow of 1600 million years ago) is very important to us because only with this fossil, we can tell whether the land animals whose fossil was found of 400 million years ago really made good progress from timeframe 1600 million years ago to timeframe of 400 million years ago.
If the question is around rate(of change), you must know the timeframe to calculate the change.
(A) Known fossils of early land animals include fossils of animals that lived relatively soon after the first emergence of land animals. A explained as above
(B) Fossils from the late Silurian period represent only a small number of the animal species that were alive at that time.Even if you have less or more of fossils, still they will be able to prove, so no effect on argument
(C) No plants were established on land before the late Silurian period.Plants are out of scope. Argument is about animals, in fact specifically land animals
(D) No present-day species of aquatic animal is descended from a species of animal that once lived on land.Same as D.
(E) All animals alive in the late Silurian period lived either exclusively on land or exclusively in the water.By negating this choice, even if we say that animals would have lived on land as well as water, we cant comment anything on rate of evolution. Moreover, this again moves away from land animals.
If you know what you're worth, then go out and get what you're worth. But you gotta be willing to take the hits, and not pointing fingers saying you ain't where you wanna be because of anybody! Cowards do that and You're better than that!
The path is long, but self-surrender makes it short; the way is difficult, but perfect trust makes it easy.
Fire the final bullet only when you are constantly hitting the Bull's eye, till then KEEP PRACTICING.
Failure establishes only this, that our determination to succeed was not strong enough.
Getting defeated is just a temporary notion, giving it up is what makes it permanent.
Press +1 Kudos, if you think my post gave u a tiny tip.
