First of all,we need to use "evolved" and not "evolve". So B and C are out.
Secondly, "whereby" seems to refer to something which happened due to something else. For instance, "We have X,whereby Y" suggests Y happens because of X.This surely isnt applicable here as "species
evolved over time from a single ancestor or very few common ancestors" is Darwin's theory and not something which happens because of the theory. Hence D and E are out.
Hence IMO is A. Do post the OA.

Hi all!
Few answer choices contain verb tense errors. There is 3/2 split.
B, C and D are wrong.
'whereby' means also 'in accordance with which'
I choose A. It is clearer for me.

which is correct: "theory in which" or " theory whereby"?
This question is from 1000 series. According to it, he OA is D.
1- Is the verb tense correct i the OA? 'have evolved' gives the meaning that it is started in the past and still present or its effect still exists. it is very weird.
2- What is the difference between whereby & in which? which one is correct?
Thanks in dvance

Generally, the usage of a present perfect verb implies that the subject of the verb still exists.
Incorrect:
The dinosaurs have evolved over time.
The sentence above is illogical because the verb in red (present perfect) implies that the dinosaurs still exist.
D: All species have evolved over time.
Here, the verb in red (present perfect) implies that all species still exist.
Since some species have died out -- the dinosaurs, for example -- option D is illogical and thus not viable.
I recommend that you disregard the SC above.
a theory in which X2- What is the difference between whereby & in which? which one is correct?
Thanks in advance
a theory whereby X
Both constructions are viable and seem so close in meaning as to be indistinguishable.
