Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
The process by which living things change over a period of time is called evolution. Evolution occurs through natural selection, genetic variation, and environmental pressures, leading to changes in the genetic makeup of populations over successive generations.
Things that do not contribute greatly to evolution include individual organism's desires or needs, acquired traits during an organism's lifetime, and random or chance events (such as mutations that do not confer a survival advantage).
evolution
Stochastic process is also known as a random process. It is a collection of random variables that represent the evolution of some system of random values over time.
Common misconceptions about evolution include thinking that it is a random and purposeless process, that humans evolved from monkeys, and that evolution is always a slow process. In reality, evolution is a non-random process driven by natural selection, humans did not evolve from monkeys but share a common ancestor, and evolution can occur rapidly in response to environmental pressures.
Natural selection is not random in the process of evolution because it is based on the survival and reproduction of individuals with advantageous traits that help them adapt to their environment. This leads to the gradual accumulation of beneficial traits in a population over time, resulting in the evolution of species.
No, evolution is not a passive process. It occurs through a combination of random genetic mutations and non-random natural selection, driving the adaptation of species to their changing environments over time. Organisms actively interact with their environment, leading to genetic changes that can impact their survival and reproductive success.

Evolution is a theory that all species are constantly evolving. It states that evolving can be faster in certain circumstances. Random events, especially geographical, are one of these cicumstances.
The idea that evolution is a directed process with a predetermined goal or purpose is not part of Darwin's theory of natural selection. Instead, Darwin proposed that evolution occurs through random variation and selection based on the fitness of individuals in a given environment.
Marlins adapt to their environment the same way all living things do, by the process of evolution via natural selection and random mutation.
A random process is a sequence of random variables defined over a period of time.
Mutations are random... they can be good, bad, or neutral.Natural selection makes evolution a non-random process by making it more likely that organisms with bad mutations will die without mating, while those with good mutations will live on to pass the gene to the next generation making it more fit.
No. Natural selection is a directed process and genetic drift and gene flow could be said to be random; something that could happen in no set order.
Darwin considered evolution to be caused due to : 1)small changes/variations that occured 2)these variations were directed specifically towards adapting to the environment(directional) 3)evolution was a slow process De Vries believed that evolution occured by: 1)large changes that occured 2)these changes were mutations and were stochastic or random, not directional 3)evolution occured in fits and starts and was not a slow ongoing process
