Selective eating just an evolutionary trait?

Babies will put almost anything in their mouths. But as children get older, they become more selective about what they eat,// particularly if they have not tried it before.

Crooked teeth may be due to evolution and overcooked meals

According to Peter Lucas of George Washington University, while presenting a paper at the AAAS Meeting in Washington,// US, chopping of vegetables to bite size pieces and cooking them to into mashed textures may be one of the reasons that our teeth are growing crooked and badly formed. Thus congenital bad shaped teeth may be a direct result of evolution than anything else. Human teeth...
