If I think humans are the hightest form of life then they're different than apes. I've enumerated the differences in more than one post in this thread, it'll be up to you to quantify the differences.
Quantifying differences is subjective. How about this, humans are a lot different than apes. Use whatever value of 'lot' you wish in your quantification.
Again, you're not defining the value of 'more', 'less' or 'equally'. Think about it, 'equally different' makes no sense unless it value is established.
Define 'more', 'less' and 'equally' different. Place a value on the terms.
