Malthus's ideas on population growth and resource limitation suggested that populations tend to outstrip their resources, leading to competition for survival. Darwin applied this concept to his observations of natural variation among species, concluding that those individuals better adapted to their environment were more likely to survive and reproduce. This process of "natural selection" became a cornerstone of his theory of evolution, illustrating how species evolve over time in response to environmental pressures.
Charles Darwin formulated his ideas about the origin of species primarily during his voyage on the HMS Beagle, where he observed diverse plant and animal life in various environments, particularly in the Galápagos Islands. These observations, combined with insights from geology, artificial selection, and the work of contemporary scientists like Thomas Malthus, led him to contemplate natural selection as a mechanism for evolution. The variation and adaptation he noted in species suggested that they evolved over time through a process of descent with modification. Ultimately, these insights culminated in his groundbreaking work, "On the Origin of Species," published in 1859.
Darwin concluded that the animals at the Galápagos Islands exhibited distinct variations that were adapted to their specific environments. He observed that species such as finches and tortoises had evolved different traits based on their particular habitats and food sources. This led him to propose the theory of natural selection, suggesting that these adaptations occurred over time as a result of environmental pressures. Overall, the Galápagos Islands played a crucial role in shaping his ideas about evolution.
Darwin was encouraged to publish his theory of evolution primarily by the naturalist Alfred Russel Wallace, who independently developed similar ideas about natural selection. In 1858, Wallace sent Darwin a manuscript outlining his findings, which prompted Darwin to finally present his work. This led to the joint presentation of their papers to the Linnean Society of London, ultimately motivating Darwin to publish his seminal work, "On the Origin of Species," in 1859. The urgency created by Wallace's correspondence spurred Darwin to share his extensive research and ideas with the world.

Darwin's procrastination in publishing his ideas was influenced by several factors. First, he was concerned about the potential backlash from the religious community and the societal implications of his theory of evolution. Second, he sought extensive evidence to support his ideas, which led to years of meticulous research and observation. Third, Darwin experienced personal health issues that hindered his ability to work consistently. Finally, he was aware of the competitive pressure from other naturalists, notably Alfred Russel Wallace, which contributed to his hesitation.
Darwin was influenced by ideas from other scientists such as Lamarck's theory of acquired traits and Malthus's principle of population. These ideas contributed to Darwin's concept of natural selection as the mechanism for evolution. Ultimately, Darwin's observations and synthesis of these ideas led him to develop his theory of evolution by natural selection, which revolutionized the field of biology.
Charles Darwin's studies in the natural world actually led up to the discovery of natural selection. Darwin observed the population barnacles and later pigeons to observe variations as they were crossbred within their own species.
Darwin observed that high birthrates and a shortage of life's necessities forced organisms into a constant "struggle for existence", both against the environment and against each other is which led Darwin to propose his theory of constitution
Malthus study philosophy and mathematics at St. Johns College in Massachusetts. Malthus's achievements led to a career as a nationally recognized economist.

Malthus's idea was that our food production grows at a linear rate, while our population grows logistally. More people are being born than can be fed. Thus this leads competition for survival. Darwin observed that this is true for all organisms. More offsprings are born than can be sustained, thus leading to differential survival of organisms, thus natural selection.

The gold-foil experiment led scientists to conclude that an atom's volume is mainly unoccupied.
Charles Darwin observed that the beaks of several finches on the Galapagos Islands were adapted to specific purposes, and that, while they were all finches, they had adapted different characteristics to perform different functions (different feeding for differently shaped beaks). This led him to conclude that organisms can and do change to perform necessary tasks more conveniently. He expounded upon this conclusion, eventually publishing his renowned On the Origin of Species.
