That's not a very good description of the process of species diverging over time, as they become geographically separated and adapt to local conditions.
There are initial conditions for evolution: one is the existence of a species, the other is environmental conditions, which provide the natural selection--in essence this "forces" the DNA of a species to diverge and radiate. All the different species are related by having had a common ancestor before populations with the ancestral genes got separated.
Insufficient. You must specifically define the inital conditions.
