Textbook Question
Chapter 14, Problem 27PDQ
It is estimated that about 0.2 percent of human mutations are due to transposon insertions and a much higher percentage of mutational damage is known to occur in some other organisms. In what way might transposon insertion contribute positively to evolution?

Students have asked these similar questions
Highly conserved genes such as those for ribosomal RNA are present as clearly recognizable relatives in all organisms on Earth; thus, they have evolved very slowly over time. Were such genes “born” perfect?
What are the types of transposons? Please explain in detail how transposons contribute to genome evolution.
As discussed, the overall rate of mutations in humans is estimated to be about 1 × 10−8 mutations per base pair per generation. How many new mutations would you expect each person to carry, on average, based on this mutation rate? Other studies have estimated that each person carries about 100 new loss-of-function mutations. How does this number compare with your estimate of the number of mutations based on the mutation rate? What might account for any differences?
