Is Evolution Observable?

[Anomalocaris]

Every time some reproduces it evolves duh! All evolution entails is mutation x reproduction= evolution

Ah, no, Mutation makes evolution possible, but evolution is not just mutation.

Evolution is about changes in physical expression of genes in a way that makes a difference to how the animal lives.

For example, mutation and genetic drift has been accummulating for tens or even hundreds of millions of years in some species of living fossils like coelacanth. In fact the amount of mutation and genetic drift that has occurred to the coelacanth lineage since Cretaceous would be similar to the amount that has accummulated between the very first shrew like placental mammals and modern humans.

Yet with similar amount of accummulated mutations, coelacanth would not be considered to have evolved much from their cretaceous ancesters, humans would have been considered to have evolved a vast amount. This is because the same gross quantity of accummulated mutation has not expressed themselves in ways that made much difference to how coelacanth lived, while it made a vast difference in how the lineage of humans had lived since its tree shrew days.
