Question

From a phylogenetic perspective, asexual species of complex animals (fishes, amphibians, reptiles):

a) Are more common than sexual species.
b) Are less common than sexual species.
c) Exhibit more genetic diversity.
d) Evolve faster.
e) Have shorter lifespans.

Answer 1

Asexual species of complex animals like fishes, amphibians, and reptiles are less common than sexual species, mainly because sexual reproduction provides greater genetic diversity which is important for survival.

Step-by-step explanation:

From a phylogenetic perspective, asexual species of complex animals such as fishes, amphibians, and reptiles are less common than sexual species. While asexual reproduction has some advantages such as no need for a mate and the potential for rapid population growth, the lack of genetic diversity due to offspring being genetically identical to the parent can be a disadvantage, especially in changing environments. Multicellular organisms that depend entirely on asexual reproduction are exceedingly rare because sexual reproduction provides significant advantages in terms of genetic variation, which is essential for the survival and reproduction of the population amidst environmental changes.
