Answer 1

The Correct Option is A

A. Living Fossil: The coelacanth (Latimeria) is a living fossil, a species that has undergone minimal evolutionary change over millions of years, mirroring ancient fossil specimens. A-IV
B. Connecting Link: The echidna (spiny anteater) displays traits common to both reptiles and mammals, classifying it as a transitional species between these vertebrate classes. B-III
C. Vestigial Organ: In humans, the vermiform appendix is a vestigial organ, a bodily structure that has largely or entirely lost its original evolutionary purpose. C-II
D. Atavism: The occurrence of elongated canine teeth (sometimes termed "vampire teeth") in humans exemplifies atavism, signifying the re-emergence of an ancestral characteristic that was previously absent. D-I
