Prompted by observations of seemingly related species in

Question

Prompted by observations of seemingly related species in neighboring locales that he made during his five-year voyage around the world on the HMS Beagle, Charles Darwin conceived his theory of natural selection  in which all species evolved over time from a single ancestor or very few common ancestors.

A.in which all species evolved over time from a single ancestor or very few common ancestors

B.in which all species evolve from a single ancestor or very few common ancestors over time

C.whereby over time all species evolve from a single ancestor or very few common ancestors

D.whereby all species have evolved over time from a single ancestor or very few common ancestors

E.whereby all species evolved over time from a single ancestor or very few common ancestors

Minheequang · Answer

IMO  E

Prompted by observations of seemingly related species in neighboring locales that he made during his five-year voyage around the world on the HMS Beagle, Charles Darwin conceived his theory of natural selection  in which all species evolved over time from a single ancestor or very few common ancestors.

A.in which all species evolved over time from a single ancestor or very few common ancestors -->  in which  seems incorrect. It means  all species evolved in his theory of natural selection . Also, this structure is redundant with the existence of another prepositional phrase:  from a single ancestor or ...

B.in which all species evolve from a single ancestor or very few common ancestors over time --> same error

C.whereby over time all species evolve from a single ancestor or very few common ancestors -->  evolve  is not correct. It should be  evolved

D.whereby all species have evolved over time from a single ancestor or very few common ancestors --> have evolved  is not suitable when being used in a past context

E.whereby all species evolved over time from a single ancestor or very few common ancestors -->  best. correct tense  evolved , correct use of  whereby  and no distortion of original meaning

in which Vs whereby - whereby win. A & B - out
evolve vs evolved - evolved wins. C - out
D - have evolved, wrong tense

E

D.whereby all species have evolved over time from a single ancestor or very few common ancestors

E.whereby all species evolved over time from a single ancestor or very few common ancestors

I think it is A.

A describe of his theory has to be "in which" because you are going "into the theory" to explain the logic. So it leaves A & B. We are talking in the past tense therefore it has to be A.

Trying to think iof examples where whereby is used.

He made a declaration whereby all slaves were free to do what they want.

I think it's "in" because it's a theory.

What is stated in Einstein's theory?
What is stated by E's theory?

OA pls?
pretty pls.
with sugar on top?

bigfernhead · Answer

I went with A, then E, and then back to A.

Now I'm confused between the meaning of IN WHICH and WHEREBY.

Anyone have a link where I can read up?

bigtreezl · Answer

B

on second read I go with B, because evolution is continous. Thats my final answer!

Hades · Answer

A/D/E are out as that implies species stopped evolving, which is false (logical error). B/C remain. B has a misplaced modifier. Final Answer, C , although I don't like it. If it's E this is not an Official question.

dwivedys · Answer

Charles Darwin proposed a theory explaining a certain observation; he did not propound a fact. Usually, the present tense is used to denote facts: I like Mangoes. (Not: I liked Mangoes).
Choice C seems to suggest this observation (over time all species evolve) as a fact; so I don't think that's right.

Choice A: All species evolved over time ... the phrase over time indicates the desired continuity over time and does not signal a complete stoppage of the evolution itself. Besides the intent is to indicate that the species evolved from a common ancestor ... not so much whether they are still evolving or not.

However all the above notwithstanding, I feel that "theory in which" sounds a bit suspect; at any rate I am not comfortable with it. But there is no other choice because theory whereby also doesn't seem quite right. So I choose A.

Pls let us know the OA

tkarthi4u · Answer

i choose Where by over inwhich. So E.

DenisSh · Answer

First, let's decide between  in which  and  whereby .

in which  is  wrong  because 'in theory' (inside it) cannot evolve species.
By the way,  whereby  actually means 'by which way or method'

Thus, go further with  whereby :

C. whereby over time all species evolve from a single ancestor or very few common ancestors -  changes time of verb 
D. whereby all species have evolved over time from a single ancestor or very few common ancestors -  changes time of verb 
E. whereby all species evolved over time from a single ancestor or very few common ancestors -  the best answer

IMHO, (E)

sondenso · Answer

Whereby =by which theory, not by which way

The sentence does not mean that species evolved in the theory, but does mean that the theory mentions that the species evolved....

C, D , E out

A is the best

neeshpal · Answer

I am stuck between B and D

I dont know the use of whereby vs. in which

I'll go with D

taekyuchoi · Answer

Rampuira,

Where do you get these questions from?
you should post OA for each question you post.

azurik12x · Answer

I choose E.

"whereby" makes more sense than "in which" because it explains his theory of what has happened over time; the way that something has occurred. "evolved" makes the most sense because it explains his present theory - where humans came from. We evolved from "a single ancestor or a few common ancestors"

urchin · Answer

Wats the OA ???????

I'm confused over A and B.

fozzzy · Answer

THe OA is D but why D? can someone explain!

pqhai · Answer

Hi fozzzy. My reason for D is:

Prompted by observations of seemingly related species in neighboring locales that he made during his five-year voyage around the world on the HMS Beagle, Charles Darwin conceived his theory of natural selection  in which all species evolved over time from a single ancestor or very few common ancestors.

A.in which all species evolved over time from a single ancestor or very few common ancestors
 Wrong.  
- "in which" is incorrect because  species cannot evolve in natural selection . They must evolve through/by the natural selection.  
- If you use past tense (evolved), you imply that all species stopped evolving. Or the evolution is done! Nope, all species continue evolving.

B.in which all species evolve from a single ancestor or very few common ancestors over time
 Wrong.  
- "In which" is incorrect.

C.whereby over time all species evolve from a single ancestor or very few common ancestors
 Wrong.  
- Simple present tense does not convey the best meaning. Present perfect tense conveys idea much better.

D.whereby all species have evolved over time from a single ancestor or very few common ancestors
 Correct.  
- "whereby" = by which
- Present perfect tense is correct.

E.whereby all species evolved over time from a single ancestor or very few common ancestors
 Wrong.  
- If you use past tense (evolved), you imply that all species stopped evolving. Or the evolution is done! Nope, all species continue evolving.

Hope it helps.

Regards.
