Are there any other animal species showing signs of advanced intelligence like humans?

I don't know exactly how to word it, and I don't want to mislead someone to answer thoroughly but be off the meaning of my question. I know evolution takes a long time compared to a human's perspective, but have species been recorded to show particular evolutionary progress similar to humans? I understand certain ape species use tools, and hunting in packs etc, but are there any species that are showing that NEXT step?

Do we have the capabilities to track historical data on this? Or would the time scale be way too much for us to even consider given current technology?

Dolphins, certain apes, elephants, crows (and similar birds), pigs, pigeons, squirrels, and rats are all considered highly intelligent creatures. But they don't tend to plan ahead in the way that humans do, which has been a big stipulation in determining human level intelligence.

There has been one chimp that's been hiding rocks that he plans to throw at visitors to his zoo enclosure. But until now that behavior was thought to be exclusive to humans.
