Areopagite, you answered my question very well actually.

But perhaps I can state it more simply and clearly: How can one discern between scientific claims that are distortions of the truth, and ones that are genuine facts? Since most of us can’t scientifically verify the claims ourselves.
First, look at the various branches of science.
Astronomy: Only a small amount of actual matter exists in space. However, there have been recent claims regarding Dark Matter and Dark Energy. Neither has been proven. The point to watch out for are claims that the stars are a certain distance away. This is based on a phenomenon called “red shift,” which is currently being challenged. The stars may not be as far away as we once thought.
Biology: The one science which is the primary focus of atheists. It is currently being used to sell the idea that a self-generating machine called evolution selects self-generating organisms which inexplicably become more complex. There is currently no rational explanation as to why say, asexual cells developed into more complex sexual organisms or why fish became amphibians which became land dwelling creatures, or so the story goes.
In regard to human origins, there is a fictional story that at some point in human development, our hominid ancestors reached a level of “neurological awareness” and had souls dropped into them. This assigns the soul and even human consciousness to purely biological forces, which were explicitly not guided toward any goal.
Catholics should be careful as regards any scientific claim, or pseudo-scientific claim, that cannot be demonstrated by science. There are no peer reviewed science papers regarding the soul entering the supposed hominid line, thereby elevating us to being able to communicate with God.
For them, science has become the new circumcision, strongly suggesting that without acceptance of evolution, we are not being reasonable or rational. Do not be overly concerned aout this. As Pope Benedict stated regarding a certain remark made by Pope John Paul II and widely hailed by atheists/secularists: “But it is also true that evolution is not a complete, scientifically proven theory.”
The rest of biology, from the human genome to bioinformatics, is quite easy to comprehend and demonstrate. It deals exclusively with things that are alive right now.
Chemistry: Originally, plants and their parts were our medicines until synthetic substances appeared. Some of these began as dyes for fabrics which were discovered to have medicinal properties. Chemistry also provided fuel and lubricants and helped build the first nuclear reactor. It provided explosives and rocket fuel.
The Church founded universities which were later infiltrated by people who wanted to remove God by subtle and not so subtle means. Study history and go to your library. The internet is a good starting point but seeing the answers to your questions in print is the best way to go.
By their fruit you shall know them.
The Church has a Pontifical Academy of Sciences. Catholic authors publish many books about many subjects that include the sciences. Consult them.
Peace,
Ed
