I re-watched the movie today, after taking a day to calm down over the horrors of the day before (
).
During the chill out moment at Nolans' summer retreat, they talk about how they come back each season, bringing something new to the table, ex... new weapons, armor, tactics... etc, Spetznatz mentions 'like evolution, trying to be better killers'...which got me thinking.
I figured, it wouldn't be a far off shout to say that yes there could be a break off point between the species at one point when one clan decided that biological improvements were needed to make them the better 'hunters'. By doing this there could have been a mutation with their DNA, which meant that the following generations would suffer side effects such as aggressiveness, becoming more sadistic in nature as in being more about the kill than the hunt, deformed facial features... etc.
Trade-off with this 'improvement' by the offending clan; is that the main clans looked down on the biological method of improving themselves, and saw it as 'cheating'. Who then cast out the clan, who then take it personal and to prove they are the better hunters; start hunting the normal clans.
Their technology is similar, but not the same. Did anyone notice the difference between SP's arm console with that of the classics?
