It’s a rather obvious prediction. If cetaceans evolved from terrestrial mammals then there should have been species at some point that had a mixture of cetacean and terrestrial mammal features. We can look at fossils to see if there are any that have that mixture of features.
What changes are you looking for?
Again, what changes are you looking for?
Given your stubbornness in other posts, I doubt that you would even count that as a verification.
It’s just a matter of want-to and time. If you want to learn this material there is nothing stopping you.
You can prove the overarching concept of evo to be wrong. It is a very falsifiable theory. The link I gave you lists 29 such potential falsifications. Here is an example:
In other words, the tree of life based on the physical characteristics did not correlate with the tree of life based on DNA sequence then the theory would have been proven wrong.
You can do the same with the distribution of physical characteristics in both living and fossil species and the DNA sequences of genomes from living and extinct species. This type of data can be used to test conclusions within the theory of evolution. It is all observable and repeatable.
The mixture of features in fossils is observable and repeatable. The theory of evolution makes predictions about which mixtures of features you should and should not see.
And humans are still apes, still primates, still mammals, still amniotes, still vertebrates, and still eukaryotes.
YEC is misrepresenting how science is done. They incorrectly claim that you should be able to observe the hypothesis. That isn’t how science is done. Observations and hypotheses are separate things. Everything we use to test the theory of evolution is observable right now.
