How does the descent of modification occur? what are the environmental factors involve?
Although Charles Darwin is widely regarded as the “Father of Evolution,” the fundamental principle was developed by both Darwin and Alfred Russel Wallace. Both scientists based their findings on studies of natural population diversity. Darwin's work, in particular, concentrated on animals from the Galapagos Islands, especially finches. The notion that animals changed as a result of natural selection forces gave rise to the concept of evolution over time. Data accrued over time, such as the Grant research team's long analysis of Galapagos finches, has validated this hypothesis and elevated it to the level of a biologically supported theory.
Temperature, food, pollution, population growth, sound, light, and pests are all environmental influences. The variety of environmental pressures that have been found to enhance asymmetry is most likely not exclusive; many other types of stress can have similar effects.
Darwin concluded that natural selection was an unavoidable result of three natural laws. For starters, certain species' traits are hereditary, or passed on from parent to offspring. While no one understood how this was at the time, even Darwin and Wallace, it was widely accepted. Second, more embryos are produced than can survive, resulting in a scarcity of resources for life and reproduction. Both species' reproductive capability exceeds the supply of resources to sustain their numbers.
As a result, each generation competes for certain tools. Both Darwin and Wallace gained an appreciation of this theory after reading an article by economist Thomas Malthus that addressed it in relation to human populations. Third, offspring differ in terms of their traits, and those differences are hereditary. Darwin and Wallace reasoned that offspring with inherited characteristics that enable them to compete for scarce resources are more likely to succeed and have more offspring than those with differences that are less able to compete. Since characteristics are hereditary, they will be more prominent in the next generation.
This would result in population transition over centuries, a process Darwin referred to as descent with alteration. Natural selection, in the end, leads to greater population adaptation to the environmental environment; it is the only mechanism responsible for adaptive evolution.
