What does this mean?

"Its musculoskeletal system was originally adapted for terrestrial bipedal saltation but over its evolution its system has been built for arboreal locomotion"

If you can tell me what it means without googling it I will shout you a curry.

It's an example of scientific text.  Sometimes such text is needed for precision but the above text means something really simple

With my background in Latin I understood it immediately but such a background is rare these days

Words and names from Latin and Greek are very common in scientific text

Here's one name that was a common spelling test when I was a kid.  Very few could remember the spelling of it or even the pronunciation.  It is "ornithorhynchus".  It simply means "bird nose".  Can you guess what it is?

UPDATE: It's a quokka. Saltation is from saltare, the Latin word for "jump". It now climbs instead of jumping
