A biology question here “As more evidence gathers science is replaced with better science use real life example to explain this”

Answer 1

When butchered Homo erectus bones were discovered in a cave context with lots of other butchered animal bones at the Zhoukoudian site in China, researchers first assumed that H. erectus individuals were living in the cave and that the bones were remains of their meals. The inclusion of H. erectus bones with other animal bones was interepretted as evidence that H. erectus was cannibalizing their own species. But years later when additional analyses were performed on the bone assemblage from the site, researchers had better technology and more data available to them and they noted that the butchered bones of both animals & H. erectus displayed only teeth marks from a large carnivore and not teeth or tool marks from the H. erectus hominin which put the cannibalism interpretation in doubt. Turns out that H. erectus was not living in the cave, but a giant species of hyena was and the bones in the cave were the remains of its meals. H. erectus was on the menu for these hyenas. So H. erectus was not cannibalizing their own species.

Answer 2

Most close to home, consumer goods we use all the time have been refined and improved specifically because of scientific testing and analysis. For instance, modern vehicles give you a better chance of surviving an accident than say 50 years ago, because of better science through research (and lots of crashed cars and dummies!).

Other examples that come to mind are public health issues such as lead paint or asbestos, where increasing evidence to its harm, leads to public policy outcomes such as banning or phasing out the use of a chemical. A recent example is the phasing out of Teflon coated non-stick cooking pans, because of mounting evidence of harm to consumers.
