I think Catholics should be aware of the mind-boggling complexity of biological systems in order to teach others that life is too complex to have come about by chance, and therefore a God, and only one God, could have created life. I know this goes against what many scientists and much of the media try to tell us, and I will not speculate on their motives. People should be like jurors in learning facts and considering them in order to think for themselves. I have a relatively short post that shows, with pictures, just a small sampling of biological complexity. It is at:

Even if you don’t read the post, go down to the diagrams and you will see that the cell carries on a myriad of intricate biochemical reactions. The first diagram shows an overview of biological systems, such as respiration, the next shows an example of the chemical reactions in that system, the next shows the makeup of a specific chemical in that reaction (a protein) and the next is a picture of the protein. So it starts in general and gets more specific as you go down.
In the same vein, the Intelligent Design community just made a video of how DNA works to make proteins and why they believe that only an Intelligence could have brought about our biological systems. It runs about 20 minutes and is found in this post:

Once you believe only one God was involved in making life, we narrow it down by certain historical events in which we have witnesses who wrote about them. In the Bible we have witnesses who heard Jesus Christ say He would die and then rise again on the third day and these same witnesses saw Him after His death. There are other factors that carry weight, which are listed in my short, free booklet, “Heaven’s Passport” which you can read online and/or download:

The more we learn through research, the more we should realize how phenomenal life truly is and give credit where it is due.
