Some notes off the top of my head, as an evolutionary biologist. I must say I enjoy this song very much as a card-carrying #ScienceIsMetal enthusiast...
"The Great Dark Between The Stars": well, yeah, it means whatever you want it to mean ;]
"aye-aye": a primate
"floating pale blue ark": well, Earth
"Shrew that survived": reference to small mammals in Mesozoic
"Tiktaalik take her first walk": "transitional form" between fish and amphibians, a lot like a fish with legs, discovered in Canada, one of the first terrestrial (partially terrestrial) vertebrate organisms
"Panthalassa": the counterpart to Pangaea. When there was 1 supercontinent, there was also 1 superocean!
"eukaryote... the very first one": probably referring to LECA, last eukaryotic common ancestor. "the one we'll soon become" could refer to evolution in the future or in the past.
