The similarities between sugar gliders and flying squirrels are due to c) convergent evolution.

Here's why:

Convergent evolution is a process in which organisms that are not closely related independently evolve similar traits or characteristics as a result of having to adapt to similar environments or ecological niches.

In the case of sugar gliders and flying squirrels, they both have a similar body structure that allows them to glide or 'fly' through the air. Despite being from different parts of the world (sugar gliders are from Australia while flying squirrels are from North America and Europe), they have both developed this ability to glide from tree to tree in order to escape predators and find food. This is a classic example of convergent evolution, where two species have independently evolved to have similar traits due to similar environmental pressures.

Paedomorphosis and heterochrony are terms related to the timing and rate of development in organisms, while polyploidy refers to the condition of having more than two complete sets of chromosomes, which is not relevant to the similarities between sugar gliders and flying squirrels.
