Fruit Fly 3

This picture is from the FlyBase website, where you can see more pictures and the citations for the artists. FlyBase is a collaboration of Harvard University, Indiana University and the University of Cambridge UK funded by the National Human Genome Research Institute (NHGRI).

The picture gives you an idea of the life cycle of the fruit fly. The adult lays eggs (gametes), an egg becomes an embryo and develops into the larva. The larva has cells which eventually become the forms of the adult. The pupa is covered by a shell and the adult eventually emerges (metamorphosis) to complete the cycle. A cycle can happen in as little as a week.

Scientists are finding that many organisms share the same types of genes in the developmental process. This is a tantalizing discovery for them, since it makes it seem like there are enough similarities to assume that nature alone has the ability to bring the changes about. But, as we will talk about in the future, the process has great barriers to total-natural evolution theory (materialistic, naturalistic evolution nickname I'm now using) . I am adding another article to the list on the right by Stephen Meyer of the Discovery Institute. It is the article featured in the movie Expelled that gave the scientific community shudders because it mentioned "Intelligent Design." It points out the many super-structures which have to be dwelling within the organism simply to bring about its existence as we know it. (For newbies to the internet: the article came up in a separate window when I tried it, so just close the window when you are done and want to come back here).
