What do you infer from the resemblance between flying squirrel and flying phalanger with reference to their evolution.

Explanation

**Step-by-step Solution:**

1. **Understanding the Organisms**: The flying squirrel and the flying phalanger are two different species that exhibit similar adaptations for gliding. The flying squirrel is a placental mammal found in various parts of the world, while the flying phalanger (or sugar glider) is a marsupial native to Australia and New Guinea.

2. **Geographical Isolation**: The two species evolved in different geographical regions. The flying squirrel is found in the Northern Hemisphere, while the flying phalanger is found in Australia. This geographical isolation is significant in understanding their evolutionary paths.

3. **Adaptive Radiation**: Both species have undergone adaptive radiation, which is the process where organisms diversify rapidly into a variety of forms to adapt to different environments. In this case, both the flying squirrel and flying phalanger adapted to a gliding lifestyle, which is beneficial for escaping predators and moving between trees in their respective habitats.
