It looks like from the equation on the web page it would end up at about 2.4. I had to guess its body mass - it's not a simple ratio but depends on total mass. This is because smaller animals tend to have a larger brain to body mass ratio without an appreciable intelligence advantage. However, 2.4 is no doubt wrong as the page says the equation is limited to mammals - I assume there are different constants involved with reptiles, fish, amphibians, birds, etc. It doesn't look like it gives the appropriate equation for any but mammals.
On the original topic, I'm afraid the life form destined to take over after our demise would have to be
artificially intelligent robots
