We're already percolating and during these years the principle of natural selection had already been recognized natural selection is the process that leads to the survival and reproductive success organisms best adapted to their environments and that causes the selective elective reproduction of the best genetic qualities but darwin and wallace's work put a spotlight on natural selection after reading robert chambers. I book vestiges of the natural history of creation wallace became intensely interested in figuring out how evolution works he traveled and collected and studied studied plants in animals in eighteen fifty four he left for an expedition to the malay archipelago and spent years studying specimens in writing and contemplating evolution in eighteen fifty five while he was answer raw walk in borneo he wrote a paper titled on the law which has regulated the introduction of new species which demonstrated his understanding of the process of evolution scottish geologist charles lyell l. red wallace's paper and began to consider theories of evolution in eighteen fifty.
