No. It is far from random, there is nothing random about it. If I were to race my three year old nephew I would win, easily. I am faster and stronger and I have more stamina. The outcome of the race would not be random, it would be inevitable. Evolution is the same. The organism that is better equipped to reproduce will have more success and therefore become dominant and potentially drive other strains or species out of existence. The only random element is the mutations that cause one animal to be more fit than another. Most are harmful and die out in a generation or some, some are neutral and make no real difference (these are the variations we look at for DNA tests in court) and a few are beneficial. The good ones are passed down and over time an accumulation of good changes causes the organism to become a different sort of organism. This could be likened to Poker. One hand is clearly better than another but the cards are dealt at random. Still, the best hand wins and the worst player is out of the game the soonest. Hope this helps!
Answer - Yes
Evolution is very random as it is based on mutations in the genetic code of organisms, although this process is random natural selection is NOT random and it is one of the main principals of this theory.
Answer 3
Yes, and no. Evolution is random in the sense that the solutions it produced (metabolic paths, body shapes, and so on) were by no means necessary outcomes, but produced by happenstances of genetic chemistry and chaotic environmental pressures. Should we rewind the clock and reset life to its most primitive form, there is no reason why the same lifeforms should evolve again. Evolution is non-random in the sense that whatever solution was produced would still have to have met the same criteria for survival and replicative ability. To summarize: natural selection limits the randomness of genetics, but by no means eliminates it.

What process thought to have changed the genetic code over billion years ago?
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.
What is the process by which living things change over a period of time?
This Process called the Environment
Which is not one of darwins four main ideas of natural selection?
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
What is the process of change over time?
Evolution, of course! Biological evolution.
What things do not contribute greatly to evolution?
one of these, chromosome number, crossing over, meiosis, or random mating
What is a stochastic process?
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.
What is a possible benefit of regulating the process of cell differentiation?
The process of random regulation is termed Evolution.
What process thought to have changed the genetic code over billion years ago?
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.
What is the difference between evolution and theories of evolution?
Evolution is a process, theories of evolution are theories which explain that process
How do the marlins adapt?
Marlins adapt to their environment the same way all living things do, by the process of evolution via natural selection and random mutation.
What is the difference between a random variable and random process?
A random process is a sequence of random variables defined over a period of time.
How does natural selection help evolution?
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.
How is theory of evolution of Darwin and Hugo deVries different?
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
Is evolution based on chance?
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.
Why is natural selection the mechanism for biological evolution not considered to be random or chance process?
Because the organisms are selected for traits that enable them to survive and be reproductively successful against the backdrop of the immediate environment. Not a random, in so set numerical order, process. Certainly not chance in large populations. ( Google genetic drift )
What color is evolution?
Evolution is a process; it doesn't have a color.
Does Evolution results from random events?
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.
