Artificial entities generated by evolution within computer systems" As a biologist, evolution (as one of the 4 unifying themes of biology) has always had a large impact on my life's experience. Evolution is both observable and measurable, it is one of the most fundamental aspects to life, and has created the diversity of life we observe here on planet earth. Genetic drift and natural selection carve and shape life to fit the planet's surface (even though as humans we'd like to think it's the other way around). Life is hard to define, every face biology knows about life remains geocentric, planets vary greatly throughout the universe. The emerged digital landscape mimics the biological one; evolution has the same effect. Only the strongest and most efficient codes will remain, and being the most adapted, they will be the most common. When time is thrown into the equation, it's obvious that the best adapted will evolve to be even better and even more efficient, giving rise to new "species" over time. These artificial entities may or may not be created by humans, who in comparison are less efficient, and less well adapted (to exist in computer systems). Silicon based life surpassing carbon based life has remained constant in biological consciousness.
