Hi,
You have mentioned car descended so didn't know that you meant cat ...
I think descended from is better used in terms of evolution...
And all these OG examples point towards that.
Can you reproduce the words od mgmat

daagh chetan2u
Sure, I'm gonna try to put this systematically.


Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.

B. that has suggested the elephant descended from an aquatic animal, its trunk originally evolving

E. to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved

So according to this question, choice B is incorrect because

" two other elements of that answer choice B are problematic:
* "has suggested" --> this is the present perfect, which is used to look back on past events that have some sort of relation to the present situation. so, "has suggested" would signify that, at some point in the (probably recent) past, this evidence has suggested what is stated here -- but that it doesn't suggest those notions anymore.
* "descended" (without "is") --> if you mean to state an evolutionary relationship, you should use "is descended". "descended", used alone, signifies literal downward motion.
"



So, in this threads original question, how can we say that the " african cat descended from" is correct when the phrase " descended from" means downward motion.

Is it clearer now?

for the same reason, even has descended is incorrect :


well, you already know the answer to this question: the one that appears in the correct answer is correct.

so, i'll assume that you're asking WHY "is descended" is correct, and not WHICH ONE.

"has descended" means "has moved downward". this can be in either a literal sense (he has descended to sea level from a height of 8000 feet) or a metaphorical sense (i don't want to descend to the level of common street thugs), but it can't refer to ancestry.

if you mean to discuss ancestry, which is clearly the case here, then you must use "is descended".

Following are two possible uses of descend from:

1. descend from someone/something: to develop from something that happened or existed earlier

2. be descended from: to be related to a person or animal that lived long ago

Both the senses seem to be correct in this context.

The above also implies that in your example the usage the elephant descended from an aquatic animal would also be correct.

However option B is wrong not because of usage ..the elephant descended from..., but because of the present perfect usage ...has suggested...

It appears that both descended from and is descended from are acceptable, given the meanings above.

If you are not clear after reading Chetan's posts above and this post of mine, please feel free to write back again. We shall be happy to help.

Could some please elaborate on the use of "which" without a comma in choice E? I thought non-essential modifers such as "which" always required a comma. Why wasn't "that" used instead?

What's the source of this question? It doesn't seem very GMAT-like at all in its presentation of choices.

Which can be restrictive or nonrestrictive in its use. It always needs a comma when it is nonrestrictive, but the usage in (E) is restrictive.
