Interesting question. Perhaps. The transposon that landed in the middle of a gene, disrupting it or changing its expression could be very important. The mutations they cause seem to be stable and we have had them with us a very long time.

What is thought to be the significance of the duplication of homeotic genes?
Compared to jellyfish, the increased number of genes made evolution of more complex body forms possible.
Why do different genes have a different molecular clock rate according to the neutral theory of molecular evolution?
Different genes have different molecular clock rates due to the amount of Cytoplasmic Dyruduemion the genes contain. The more Cytoplasmic Dyruduemion the genes have, the slower the molecular clock rate, according to the neutral theory of molecular evolution.
What is the essence of Darwin's theory of evolution?
Darwin's theory outlined natural selection, as one theory within the whole of evolution: those organisms that are better able to survive long enough to reproduce more often, will pass on the genes that result in their offspring surviving longer and reproducing more as well, resulting in that set of genes becoming more common in the population as time passes.
Ideas related to the modern theory of evolution?
Organisms best adapted to a changed environment are more likely to reproduce and pass their genes to offspring.
What is more important heredity or environment?
Envoirment is more important then heridity. Because without environment there is no chance for heridity and evolution .
How can competition lead to evolution?
Evolution can exist without competition. Competition is what gives evolution a "direction"; it's what guides evolution. Note that there's no literal competition. Individuals within a population don't go out of their way to trick one another out of resources. It's simply that some of these individuals are better at gathering resources, and at surviving, and at breeding, than other individuals. Which makes that their genes are more likely to make it to the next generation than the genes of the others.
What is being selected in natural selection?
The individual, or the genes of the individual. All organisms are variants in phenotype and behavior. So, natural selection is the immediate environment these organisms are in and those that survive and reproduce better in this environment leave more descendants which carry the genes that promoted that survival and reproduction advantage. Then those genes are more represented in the populations gene pool and this is evolution.
Why has the evolution of man remained static over the years?
It is a mistake to say that human evolution has remained static. Many people think that evolution requires morphological change, or change in physical appearance is required. That is not really true. A significant amount of evolutionary change in organisms is physiological; mutations in genes coding for proteins can result in changes to protein function and the biochemical pathways they affect, which may not necessarily result in a morphological change that can be observed. Something to think about is how modern medicine may be affecting human evolution. Consider the genes responsible for diabetes. Modern medicine, with its ability to grant diabetics longer and healthier lives (and more offspring), may be actually increasing the frequency of the genes for diabetes in the population. Since evolution is defined as genetic change within a population, this change in the frequency of diabetes genes can be looked at as human evolution in action today.
Why was the evolution of jaws an important event in vertebrate history?
The evolution of jaws is believed to be used originally for respiratory purposes. However, it is important to the history of vertebrates mainly because it allowed for more efficient eating.
Is it true that you are more than the sum of your genes?
The answer is No you are not more then your genes.
Why is natural selection the process responsible for evolution?
Well, it's part of the weakest link theory. Natural selection weeds out those who are not fit to carry on their genes. Only the best genes are passed onto further generations, leading to a more widely developed population.
What are the 4 characteristics of genes. Which one do you think is the most important?
Genes have four main structural parts - the promoter, introns, exons and the termination site (or recognition site for Rho protein). They are all very important (since exons contain the code for creating products, these could be called more important than introns - although it is believed introns still have an important role). Genes are how you get your own physical characteristics. They are the fundamental unit of heredity. Genes are found on chromosomes made of DNA. Different genes determine different characteristics, or traits, of an organism.
