How does evolution via artificial selection differ from evolution via natural selection?
If it evolution via natural selection then it is the natural that selects what traits should be passed on, for example having leg is better land animals then organisms that have leg will survive and ones that don't will die, this is natural selection, of course this happens over a long period of time. Evolution via artificial selection is where human selects the animal, perhaps the mutation may be eliminated in the wild but we think that it is suitable for our life so we mass produce the organism with that desirable trait. Like peas, ancient peas have to explode out of their pods to spread seeds but that is not good for us but then maybe one day a mutation occured and the pea pod will not explode, then we take it and breed many of that.

How does artificial transmutation differ from artificial radioactivity?
"Artificial transmutation" is a nuclear reaction induced in laboratory, its man made. Artificial radioactivity is a radioactive disintegration phenomenon supported by artificial isotopes.
Write an original definition for genetic variation?
The genetic variation of a population is a measure of how much individuals in a population differ genetically.
What are the differences between natural radioactivity nd artificial radioactivity?
Natural Radioactivity arises from radioactive components contained in nature. Artificial Radioactivity will come through element produced with in nuclear reactors as well as accelerators. Natural Radioactivity is a spontaneous process of disintegration. Artificial Radioactivity is carried in synthetically produced radioactive elements used in nuclear reactors.
What are variation traits?
Variation traits are characteristics that can differ among individuals of the same species, such as height, eye color, or blood type. These traits are influenced by genetics and environmental factors, contributing to the diversity seen within a population. Variation traits play a key role in evolution by providing the raw material for natural selection to act upon.
Charles Darwin theory?
Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related. Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature).
How does sexual selection differ from natural selection in shaping the evolution of species?
Sexual selection and natural selection are both mechanisms that drive evolution, but they differ in their focus. Natural selection acts on traits that increase an organism's chances of survival and reproduction in its environment, while sexual selection specifically targets traits that enhance an individual's ability to attract mates and reproduce. This can lead to the evolution of characteristics that may not necessarily improve survival, but increase reproductive success.
How does the process of natural selection differ from sexual selection in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms that drive evolution, but they differ in how they shape species. Natural selection is based on survival and reproduction, where individuals with advantageous traits are more likely to survive and pass on their genes. Sexual selection, on the other hand, is based on traits that increase an individual's chances of mating, such as elaborate displays or physical characteristics. While natural selection focuses on survival, sexual selection focuses on reproductive success and mate choice.
What is artificial selection in biology and how does it differ from natural selection in shaping the genetic traits of organisms?
Artificial selection in biology is the process by which humans intentionally breed organisms with specific traits to produce offspring with desired characteristics. This differs from natural selection, which is the process by which environmental factors determine which traits are advantageous for survival and reproduction in a given population. While natural selection occurs in nature without human intervention, artificial selection is driven by human choices and preferences.
How do natural selection and sexual selection differ in their roles in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.
What are the alternatives to evolution and how do they differ from the theory of evolution?
The main alternatives to evolution are creationism and intelligent design. Creationism posits that a divine creator is responsible for the origin of life and species, while intelligent design suggests that certain features of living organisms are best explained by an intelligent cause rather than natural selection. These alternatives differ from the theory of evolution in that they do not rely on the scientific principles of natural selection and genetic variation to explain the diversity of life on Earth.
How does the theory of punctuated equilibrium differ from natural selection?
They describe different things, so they cannot really be compared. Natural selection is the mechanism that gives direction to evolution. Punctuated equilibria is a model for the varying rates of adaptation caused by natural selection.
How did Darwin's theories differ from his predecesors?
Darwin's theories were revolutionary because they proposed a mechanism, natural selection, by which evolution could occur through the adaptation of populations to their environment. This was different from the prevailing idea of fixed species created by a divine force. Darwin's focus on variation within a population and the importance of competition and survival for shaping evolution set his theories apart from his predecessors.
How does natural vegetative propagation differ from artificial vegetative propagation?

Are the theory of natural selection and the theory of evolution the same or different?
Evolution states that a species will change to become more suited to its environment. Natural selection is survival of the fittest. The newly evolved version of the species is more fit to survive, therefore thriving.
How does evolution by natural selection differ from lamarcks view of evolution?
Evolution by natural selection, proposed by Charles Darwin, suggests that individuals with advantageous traits are more likely to survive and pass on those traits to their offspring, leading to changes in populations over time. Lamarck's view of evolution, on the other hand, proposed the inheritance of acquired traits, where organisms could pass on traits that they acquired during their lifetime. The key difference is that in natural selection, the advantageous traits are already present in the population and selected for, while Lamarck's theory suggests that organisms can actively acquire and pass on new traits.
How do disruptive selection and directional selection differ in their impact on the evolution of a population?
Disruptive selection and directional selection are two types of natural selection that impact the evolution of a population in different ways. Disruptive selection favors extreme traits at both ends of the spectrum, leading to the divergence of a population into two distinct groups. On the other hand, directional selection favors one extreme trait, causing the population to shift towards that trait over time. In summary, disruptive selection promotes diversity within a population, while directional selection drives the population towards a specific trait.
How does evolution and natural selection differ?
Evolution is the change in allele frequency over time in a population of organisms. This change over time can be just recombination, genetic drift or gene flow. Natural selection can cause evolution, but individuals are selected while populations evolve, so only a selected person's progeny would be part of that population's evolution. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. So, individuals who have beneficial variations, in their immediate environment, can be selected and will pass on those variations, in their germ line, to progeny who will insert their alleles into the populations gene pool where allele frequency may change; evolution. This is soo stupid don't listen to this crap. I don't understand why all these ediots post this
