Read the following statements regarding evolutionary evidences: A. Archaeopteryx is a connecting link between reptiles and birds. B. Limulus (King crab) is an example of a living fossil. C. Reappearance of a short tail in some human babies is an example of atavism. D. Ear muscles in modern humans are fully functional organs and not vestigial. How many of the above statements are correct?

Step-by-step solution

Statement A is correct as Archaeopteryx possesses characters of both reptiles and birds, serving as an evolutionary link. Statement B is correct because Limulus (King crab) has remained practically unchanged for millions of years, making it a classic living fossil. Statement C is correct as atavism refers to the sudden reappearance of an ancestral trait, such as a short tail in a human baby. Statement D is incorrect because the auricular (ear) muscles in modern humans are reduced and non-functional, making them ves
