It is now thought that, although green plants probably evolved from the green algae and animals from some other early forms, most modern protists have followed independent evolutionary lines. So, ******No****** they have evolved individually!
When the ozone layer is formed, the life forms evolved. They were not possible earlier.
According to the theories of Charles Darwin complex forms of life evolved over long periods of time from simpler forms.
No, humans did not evolve from a star. Human evolution is a biological process that traces our lineage back to ancient primates and ultimately to the common ancestor we share with other primates. Stars are celestial bodies in space that undergo nuclear fusion to produce light and heat.

The earliest ones still around are stromatolites, but there were lots of earlier life forms.
Apes and humans share a common ancestor that lived around 10-20 million years ago. This common ancestor gave rise to both the ape and human evolutionary lines. So, apes did not evolve from humans, but rather both humans and apes evolved from a common ancestor.
Less complex life forms.

I'm assuming you mean "Biology." If so, biology is the science and study of life, in all forms, from protists and amoebas to mammals and reptiles.
