Audience: year’s five to eight

Reason for choosing the topic: I’ve found that the topic of whether the chicken or the egg came first is often brought up in general conversations, and would generate a lot of interest, as the answer could provide a lot of peace of mind.

Reason for choosing a blog: I think a blog is a different way to learn something and is more interesting, than reading a poster or a book. It also opens opportunities for discussing the subject with other people that are interested. Also as this topic is brought up in conversation a lot it is best explored in a conversational manner.

If you want to look into the topic more here are some sites I used:

So, why should you care?

Don’t pretend that you weren’t curious!

But on top of this people have made other fantastic discoveries from the research!

Like:

·       According to Professor John Harding "Understanding how chickens make egg shells is fascinating in itself but can also give clues towards designing new materials and processes,"

If you believe the chicken came first:

Dr. Colin Freeman from Sheffield University along with colleagues from Warwick University’s research would support you! They “have the scientific proof that shows that in fact the chicken came first”.

What they found was a protein, called ovocledidin-17 (OC-17), that exists only in a chicken’s ovaries and is vital to eggshell formation in chickens. The protein acts as an enduring builder that puts tiny parts of the shell together. The shell would not exist without this protein, which only exists in chickens, so the end result is that the chicken came first.

If you think the egg came first:

Your opinion would be supported by the non chicken mating theory.
Two non-chickens mated and the DNA in the new zygote (The cell formed by the union of a male sex cell and a female sex cell) contained the mutation(s) that created the first real chicken.  

This is a chicken zygote, which you may recognise as a chicken’s egg.
The zygote cell is the only place where DNA mutations could produce a new animal, and the zygote cell is housed in the chicken’s egg.
So, maybe the egg came first?

If the chicken came from the egg where did the egg come from? If the egg came from the chicken where did the chicken come from?

What do you think came first?

If you look at the life cycle of a chicken there is no straight answer....
