The person who proposed evolution as a scientific theory was CHARLES DARWIN.
 Evolution theory has to do with the process by which living organisms undergo changes over a long period of time as a result of changes in their heritable characteristics. The theory of evolution has three essential parts, which are these:
(1). The DNA of living organisms do change or mutate overtime.
(2). The changes brought about the DNA mutation can either be beneficial or harmful.
(3). As mutation occurs and continue over a long period of time, it brings about formation of new species.

Jean-Baptiste Lamarck

Explanation:

It was Jean-Baptiste Lamarck who first proposed  theory of evolution in some form. His theory of transmutation of species clearly depicted that species advances themselves based on their environmental surroundings and also says that all the species have developed themselves from a simple organism to a complex one through generations of adaptation. He also supported the thought of inheritance of characteristics from ancestors referred to as Lamarckism.

Thus, before Charles Darwin it was Lamarck who established the theory of evolution

When two black holes spiral around each other and ultimately collide, they send out gravitational waves - ripples in space and time that can be detected with extremely sensitive instruments on Earth. ... If confirmed, it would be the first known light flare from a pair of colliding black holes.
