BOOKMARKED
Thomas Henry Huxley (1825−1895), one of Charles Darwin’s earliest and most staunch defenders, as well as an influential naturalist in his own right, first observed the many similarities between reptiles and birds. Huxley noted, for example, that the wings of a bird hid reptilian fingers. Today, few scientists challenge not only the link between birds and reptiles in general, but between birds and theropods, a group of bipedal saurischian dinosaurs. Hundreds of structural similarities exist, including elongated arms, large eye openings, swiveling wrists, three forward-facing toes, and hollow bones.
The most diverse theropod group is the coelurosaurs, a carnivorous bipedal group that includes the Tyrannosaurus rex and the Velociraptor, the latter of which is quite similar to the oldest known bird, the Archaeopteryx. Coelurosauria, in fact, is the clade that contains all theropods more closely related to birds than to carnosaurs, and all coelurosaurs have been thought to possess feathers.
However, a recent find of what seems to be an entirely new—and apparently featherless—coelurosaur has complicated the subject. Several suggestions have been made as to why this particular chicken-sized dinosaur from the Late Jurassic period lacked feathers.
One possibility is that, in some creatures, feathers were replaced by scales because the feathers were not needed for warmth, recognition of family members, or mating rituals—uses that feathers were thought to have had for dinosaurs that did not fly. It is also possible that some coelurosaurs had feathers in only certain geographic areas.
Another idea is that this particular coelurosaur was so young that it had not yet grown
feathers.
A more fundamentally profound alternative is that, contrary to conventional scientific thought, birds and feathered dinosaurs developed feathers independently of each other rather than from a common ancestor. This would certainly not be the first case of what is known as convergent evolution. Fish and certain mammals can swim,but have evolved this attribute separately. Likewise, insects have wings, but developed them independently from birds. Luckily, the new fossil of what has been named a Juravenator is well-preserved almost in its entirety. More insights into why it did not have feathers will likely lead to new insights into how other animals did develop this trait.

for this passage I find it easy to understand the structure . but when answering the question, I find it hard to realize the relevant part which yielding the answers. did I read too fast?

I should read more slowly because reading that way I can find out the relevant part more easily than reading fast.

is that right?

Answer posted. Thanks for participating!



Hello Souvik

Can you please clarify the 3rd Question.
The OA says :

feathers on dinosaurs .
- might have evolved from scales (option d)

As per my understanding if the passage - Scales evolved from feathers & Not the other way round.
Also the Question mentions Dinosaurs in general & not coelurosaur .

Am i overthinking :?

Please clarify

Thank you

Responding to the questions one at a time.

First let's discuss the over all idea of the passage:

The passage discusses Huxley and his observation of the similarities between reptiles and birds.
It then discusses coelurosaurs to show this similarity and then discusses an exception (featherless coelurosaurs ) that has caused complications.

Some explanations for this contrast is provided.
Another alternate explanation that opposes the original premise (that feathers = similarity) is provided.
Authors perspective: with more study and understanding we can get a better idea about how close reptiles and birds are.

I've merely paraphrased here : the map above serves as a good reference point of what the passage discusses,
Let's go to question 1

1. In the passage, the author is primarily interested in:

(A) presenting possible solutions to a problem that has troubled scientists
for years. Irrelevant: Doesn't talk about presenting "solutions" to problems
(B) providing background information and possible explanations for a
curious discovery. Maybe: Although not the best possible description of the passage - it isn't wrong!
(C) answering critics of a controversial theory that is supported by a new
finding NO: I have a problem with the word "controversial" suggests that the author thinks that the theory isn't correct (in some way) - this isn't the case
(D) showing how an established idea can become too entrenched in
conventional scientific thought No: Again the option picks up a tone / opinion that is not supported by the author / passage
(E) presenting historical background to a current phenomenon NO: What current phenomenon?


Option B is the most reasonable response - sure it doesn't look too appealing, but few correct options seldom do!
Remember

1. Don't look for an answer that does exactly what you think the correct answer should do
2. Rather- go through each option looking for something incorrect in each - if you find even one point / perspective incorrect; get rid of that option
3. Look out for the author's tone / opinion - ensure that the answer option doesn't go away / against it (if the questions is within that scope).

Hope that helps! :)

Question 2

According to the passage, the Archaeopteryx _______________________ .


The scope for this is in the second paragraph - so let me read that scope and find out what the passage says about it.

The most diverse theropod group is the coelurosaurs, a carnivorous bipedal group that includes the Tyrannosaurus rex and the Velociraptor, the latter of which is quite
similar to the oldest known bird, the Archaeopteryx.
Coelurosauria, in fact, is the clade that contains all theropods more closely related to birds than to carnosaurs, and all
coelurosaurs have been thought to possess feathers.

Archaeopteryx is a Bird and the Velociraptor a reptile (dinosaur) was similar to this bird.

Let's look at the answers

(A) had feathers but did not fly - We have no idea if it did or didn't (remember NOT to bring background information into RC passages)
(B) is the oldest known coelurosaur Nope this was a bird!
(C) was approximately the size of a chicken We have no idea
(D) shares some similarities with carnivorous dinosaurs YES!
(E) and the Juravenator developed feathers from a common ancestor No Idea!

For such question that ask for specific info about something discussed - read the scope (the place where that entity is discussed)
and make sure that the options don't expect you to speculate - answer only based on what the passage suggests.
Remember NOT to bring background info into RC passages; respond only based on what the passage says and NOTHING else!


Hope that helps,

3. According to the passage, feathers on dinosaurs .
(A) were not used for flight - NO! We don't know this for sure
(B) were not always present at birth NO! We don't know this for sure
(C) were first noted by Huxley NO! the passage never says that it was FIRST noted by Huxley
(D) might have evolved from scales Perhaps: scope is her - "One possibility is that, in some creatures, feathers were replaced by scales because the feathers were not needed for warmth, recognition of family members, or mating rituals—uses that feathers were thought to have had for dinosaurs that did not fly."
(E) were a characteristic of all coelurosaurs ALL coelurosaurs? we don't know for sure


Option D therefore is the most reasonable response

4. Which of the following can be inferred from the passage?

(A) All adult coelurosaurs possessed feathers.
ALL possessed feathers? Can't say for sure: Eliminate
(B) Coelurosaurs who did not need feathers for warmth or mating rituals
shed those feathers for scales.
May Be
(C) Scientists have reached a consensus that certain birds and dinosaurs
are evolutionarily linked.
Proof: Today, few scientists challenge not only the link between birds and reptiles in general, but between birds and theropods, a group of bipedal saurischian dinosaurs.
YES! The proof lies here : Today, [b]few scientists challenge
not only the link between birds and reptiles in general, but between birds and theropods, a group of bipedal saurischian dinosaurs.
[/b]
(D) Thomas Henry Huxley believed in the idea of convergent evolution.
Maybe
(E) Coeulurosaurs that did not have feathers instead had scales. Maybe

The key to doing well on an inference question to is to ensure that the answer statement is 100% true ALL THE TIME!
Avoid answer options that are MAYBEs!


Hope that helps!

The 3rd question really stumps me. As discussed earlier by other posters, it is written in the passage that the feathers were *replaced* by scales. It doesn't say that feathers *went back* to being scales. The "replace" word can also suggest that there were no scales to begin with!

I have a problem with this.
The article states the opposite: feathers were shed for scales.... This means that scales evolved from feathers and not the other way around...?

Also for B :"Another idea is that this particular coelurosaur was so young that it had not yet grown feathers."

Can you explain a little more?

The answer to Q3 does not make sense at all! CrackVerbalGMAT, in the five options you mention, you have used not sure for 4 options and perhaps for D.
No way, you can conclude that D is the answer.
