, particularly to development, and that plays a pivotal role in evolutionö (p. 61). Scientists are labeling this genetic information Group II introns, sequences that invade genes that most researchers believe have evolved late in the human evolutionary chain. Scientists believe the Group II introns have the ability to insert themselves into host genomes and then splice themselves out once they are expressed as RNA (Mattick, 2004).
Protein-coding genes are responsible for forming the elements of complex organisms. However, as to where the regularly information resides for such a building complex, scientists are unsure. The new discovery regarding Group II introns means that scientists may have been able to put one more piece of the genetic puzzle together, with respect to where such information is housed and activated. As Mattick (2004) explains, ôThroughout their evolution and development, organisms must navigate precise developmental pathways that are sensible and competitive, or else they die. Generating complexity is easy;
