Some reasons:Sexual reproduction exchanges genes every generationmutationstranscription errorsretroviruses can move genes across species linesbacteria increase their diversity by exchanging plasmids (sometimes across species lines)etc.
Translocation
Genetic engineering
no it wasn't easy. but it was easier for the Early Moderns (the TUdors etc. ) to move from one class to the other!
Evolution adapts organisms via their dna and genes over periods of time for different circumstances. Survival of the fittest keeps the fittest members of a species alive to reproduce and pass on the genes that made them survive and over time the genes of the species will change to be able to survive better. So the ancestral species could go extinct so fish could into species intelligent enough to avoid nets and hook/lures and over time we won't be able to catch them and will need to move on.
No, mitosis does not allow genes to move from one chromosome to another. Mitosis is a type of cell division that results in two daughter cells each having the same number and type of chromosomes as the parent cell. Genes are not moved between chromosomes during this process.
All machines are easy to move force from one place to another.
Population is a group of organisms of the same species actively reproducing with one another. Physical barriers and distance are typical causes of different populations. An individual may move from one population to another.
The same as any another species of swan, by flying, walking, or swimming.
The concept of "jumping genes," officially known as transposable elements, was first proposed by geneticist Barbara McClintock in the 1940s. She discovered that certain genes could move between locations on chromosomes in maize (corn), demonstrating genetic variability and influencing traits. Her groundbreaking work on these mobile genetic elements earned her the Nobel Prize in Physiology or Medicine in 1983.
yes easy just blast her with nasty things about the guy
you buy and price moves easy
