Q. 18. Which of the following is an example of convergent evolution? Blind cave fish possess remants of eye structures under their scales Human embryos and fish embryos both have pharyngeal pouches Dolphins and sharks have a similar streamlined body shape Cats and buts have similar skeletal structures in their forelimbs

Answer 1

The correct answer is: Dolphins and sharks have a similar streamlined body shape.Convergent evolution refers to the process where different species independently evolve similar traits or characteristics due to similar environmental pressures or ecological niches. In this case, dolphins and sharks have evolved similar streamlined body shapes independently of each other, likely as an adaptation to their aquatic environments and the need for efficient movement in water. This is an example of convergent evolution because the similar trait (streamlined body shape) has evolved separately in two distinct lineages (dolphins and sharks) in response to similar environmental pressures.
