Well we are more like Lizects. We have spinal cords (two ofthem infact) but no heart (you may have noticed that in our treatments of your lesser species colonists). In addition we have a tri lobed brain (and tri lstringed genetics, not "DNA" as your species use), which while it can lead to greater abilities in multitasking, is sadly somewhat more vulnerable to mental illness (usually violent) than in the Humans and Advent subspecies. All that being said, we are warmlooded.

Our multiple disections of living Advant and Humans has led us to believe that modification of your genetic structure could make you excellent for slavesoldier races to delay the Stalkers pursuit.
