If human babies were born with teeth, human moms would not have to visit gyms to shed weight post pregnancy. The baby would simply eat up the fatty nutritous layer, while the mother can happily look forward to a `slim' future

Just another way to feed the sibling-a smart one as there is no need of
milk-glands.

It's bizarre!!!
Would this be considered as parental care? By feeding the young with the mom's flesh, it would promote the survival of the young (any experiment done to confirm this?). But what selection pressure had favored such a behavior?
Could the mother also benefit?

[Editor's note: our story on this paper does mention that it might be easier for the mothers to produce a nutrient-rich skin than to produce a bulky yolk in her eggs. The skin is also 're-usable' from one infant to another.]

There an interesting blog posted here on the same topic.
