The article has a nice history review of inheritance, but it would have been useful for there to be some concrete examples.
The worst example of inheritance I've ever found is in java Minecraft's mobs[0]. It is very deep in some places and has numerous examples of sub classes not fully implementing their parent interfaces.
Blaze has a bit for 'Is on fire', but how is this any different from Mob 'Is aggressive'?
Blaze > Monster > Pathfinder Mob > Mob > Living Entity > Entity

Example 1: Donkey[1]
Donkey > Chested_Horse > Abstract Horse > Animal > Ageable Mob > Pathfinder Mob > Mob > Living Entity > Entity
Example 2: Blaze[2]
