Alien: Isolation runs on an entirely new engine that was built from scratch by the Creative Assembly. The new engine allowed the development team to accommodate technical aspects like the game's atmospheric and lighting effects as well as the alien's behavioural design.
The separate populations over time may evolve distinctly different characteristics. If the geographical barriers are later removed, members of the two populations may be unable to successfully mate with each other, at which point, the genetically isolated groups have emerged as different species.Allopatric isolation is a key factor in speciation and a common process by which new species arise.he extent to which a geological barrier can effectively isolate a population correlates to the mobility of the organism or its offspring. For example physical barriers such as canyons may effectively block migration and dispersal of small mammals; however, have little impact on flying birds or wind-borne seeds.
