While living organisms tend to overprodue, the population still remains stable over time and across generations. therefore, there is competition, and success in competition is due to variability. Competition and variability together function to select the most adaptive characteristic, giving us natural selection
They thought the evolution of new species is linked to environmental changes
Overproduction
During Darwins visit to the Galapagos island he observed that these islands had many unique organisms, most of which were similar to but different from the plants and animals from the nearest mainland.... thus this indicated how population evolved. Darwin called this "descent with modification" meaning an ancestral species could diversify into many descendant species by the accumulation of adaptation to various environment. His observation described the theory of evolution.
by an asexually method
Prior to sailing on the Beagle, Darwin was yet to observe different species of animals and plants in different regions. The observations were valuable in conceptualizing evolution. Before the voyage, Darwin believed that species were confined to different geographical locations, but ideas of species adaptation and evolution were nonexistent.

Charles Darwin observed that plants and animals reproduce to further their species. While some off spring may not survive, those that do are more suited to be prevailing environment and will pass those characteristics to the next generation.
is is overproduction
"The Descent of Man" was published in 1871.
Overproduction
No, you've got it all wrong. Overproduction is when a species either production many offspring at one time because most might not survive into adulthood (Sea turtles lays hundreds of eggs but only a few will make it to the sea) or when a species reproduction at a faster rate than the environment can support (Walruses being crammed on a small beach). This type of overproduction creates tension in the species since food and shelter is scarce.
no the theory of evolution is a species becoming more advanced not over populated
