Evolution of Homeotic Gene Regulation and Function in Flies and Butterflies

Robert Warren, Lisa Nagy, Jane Selegue, Julie Gates, Sean Carroll conducted an experiment to examine the expression of the homeotic gene of butterflies. They tested the hypothesis that the homeotic gene promotes morphological changes, or the hypothesis that homeotic genes provide an existing plan for the evolution of insect subdivision diversity. Antp, Scr, Abd-A and Ubx genes were isolated from cDNA libraries and used to study differences in the number of limbs and feathers between fruit fly and butterfly. Where Ubx and Abd - A are represented, the number of limbs and feathers will appear.

I read this article in November 1999. Ghhring did a wonderful job explaining the exciting result (his lab was involved) and showed how these genes control development. Chapter 12 ("The role of homeostatic genes in evolution") is clearly written and explains the importance of a group of genes ("homeobox genes") and general animals (including humans) in the development of flies doing. Development, Gentry, Robert V., CREATION'S Tiny Mystery, (Earth Science Society, Knoxville, Tennessee State, 1986) I bought this book at UNM Bookstore in Albuquerque (April 1992). In 1981, the creation test in the testimony of Little Rock, testified as a scientist on behalf of the creation gentry was rejected for his work on his physics dissertation project I started to explain the method. The method continues to work (abandoned thirty years ago)) Fossil halo for uranium captured by granite crystals

In the early third century of the deep geology era, the homeotic genes began to lay the foundation for mysterious and wonderful things in the life of certain mammals. After tens of millions of years, primates, whales, elephants' brains and bodies grow in parallel trajectories, but also from other animals drinking milk. Therefore, modern animals such as Bonobo and Bottlenose Dolphin have a higher ratio of brain and body at every stage of growth and development.

Everyone knows that genes must be at the center of development and evolutionary mystery. The zebra looks like a zebra, the butterfly looks like a butterfly, and we seem to do for the genes we carry. The problem is that there is little clue as to which genes are important for the development of any animal. Several prominent geneticists who have been the mainstay of genetics in the Drosophila research for the last 80 years developed a plan to find ways to control flies, long-term drought in embryology finally broken down Did. Genes The discovery of these genes in the 1980's and their studies revealed the logic and order of animal morphology and created an exciting new development prospect.
