All animals have the same number of chromosomes. What is the accuracy of this statement?

The statement that all animals have the same number of chromosomes is inaccurate because different species of animals can have varying numbers of chromosomes. For instance, humans have 46 chromosomes, while dogs have 78, and fruit flies have only 8. This difference in chromosome number is due to the distinct evolutionary paths and genetic requirements of each species.

Chromosome number is a key aspect of an organism's genetics, with various species adapted to different environments and lifestyles, which influences their genetic makeup. In addition, even within the same group or family, species can exhibit significant variations in chromosome count. For example, among mammals, some species may have more or fewer chromosomes due to their unique evolutionary histories. Hence, the assertion that all animals have the same number of chromosomes is fundamentally incorrect, supporting the conclusion that the correct answer is that the statement is false.
