Well, this is part of the evolution in that where did the living things come from in the first place to be evolved. That question has to be answered to even believe in Evolution. Once you answer that question then it moves to evolution. How can one argue about Evolution when the origin of live is not yet discovered? Well, then it would lead one down the path of the supernatural creation.
For these species to evol they would have to be born or have some beginning. you have to take it back to the first cell and the first spark of life........it's actually very simple.
From a post by Dimensio:
I submit five hypothesis regarding the origin of the first life forms.From a post by Dimensio here.
a) Natural processes occuring entirely upon earth resulted in chains of self-replicating molecular strands that eventually became the first life forms.
b) Aliens from another planet and/or dimension travelled to this planet and -- deliberately or accidentally -- seeded the planet with the first life forms.
c) In the future, humans will develop a means to travel back in time. They will use this technology to plant the first life forms in Earth's past, making the existence of life a causality loop.
d) A divine agent of unspecified nature zap-poofed the first life forms into existence.
e) Any method other than the four described above led to the existence of the first life forms.
Evolution, that is, the origin of species, can proceed nicely from any one of the five origins.
