Who came first , hen or egg?
Who came first the chicken or the egg, the question shakes everyone, we all want to go from school time who has come before the chicken or the egg
What science tell :-
upon the studies of development of life on Earth answers this question. Life evolved in the oceans in much simpler form as single cell bacteria. Then, more complicated multiple cell organisms evolved. It was millions of years later, more advanced forms of life such as animals, fish birds etc. evolved.
It is found the eggs appear very first in the development cycle of species while the development of birds happened very late in the development cycle millions of years later.
For example, a lot many species both primitives and more advanced ones, lay eggs. The lizards, the fish and many smaller life forms lay eggs. The hen or the birds per se came into existence much later. Birds are advanced forms of a few of those species which lay eggs.
So, now you know, it’s the egg which came first.
