From what I understand, tree shrews evolved into apes and apes into humans.
Shrew-like mammals. Not actually shrews.
quote:
Now the discovery of a partial skeleton of a small, shrewlike mammal, described online in Nature in August 2011, pushes back the date of the divergence by 30 million years, to 160 million years ago. Found in the famous fossil beds of Liaoning, China, the newly discovered little mammal has been named Juramaia sinensis, or "Jurassic mother from China."
Yes, because the evolution between shrews and humans has not been observed.
What has been observed is that shrews and humans share a common ancestor (through two classes of sources: Morphology and Genetics). What has been observed is that the earliest mammals were small rodentish things.
There is no mechanism that can transform a shrew into a human.
Changes accruing in the genome, which in turn leads to an accruing change in the phenome (body shape). With a pruning process to weed out certain phenomes.
