the same way the 1st micro organisms that formed on this planet evolved into plants & animals.. the same way fish evolved into land animals..
evolution is a long gradual process that takes billions of years to really show off any big change..

Its like a Petrol and Diesel engine.... there different but they work on the same principal of internal combustion.
Aerobic Respiration is the same. Its the most efficient form of sending oxygen to the blood. Birds aren't mammals, there are huge difference between our amino acid chains. It makes sense that their respiratory system differs.

It may be different from other animals now, but that is because of evolutionary pressure to increase transpiration rate and decrease weight. Non-birds were not under evolutionary pressure to do this (other characteristics were more important to survival) so evolved differently.

0 - evolution is the fabricated from clinical study, no longer from any pagan faith, faith is the fabricated from pagan non secular ideals. a million - area isn't something. 2 - remember shaped from capability. 3 - rules are synthetic to describe the physics of technological know-how. 4 - remember isn't organised, it incredibly is the random bonding of like atoms. 5 - Bonding of straightforward atoms initially got here approximately in as quickly as lived suns. 6 - it relatively is now known that existence originated in area. 7 - it incredibly is the fabricated from D.N.A. 8 - there are various different forms of sexual duplicate types! 9 - it incredibly is now getting very stupid - duplicate is the survival of the species. 10 - Even sillier - an animal with a deformed neck ought to attain greater than its mothers and fathers - follow this theory and you have a giraffe. 11 - all of us originated from a single ancestor. 12 - The greater stepped forward the species the greater complicated the code. 13 - See above. 14 - See above. 15 - see above. sixteen - you need to replace your e book for an honest one on technological know-how, physics, astrophysics, straightforward biology, D.N.A. sequencing, and quantum physics. in case you think of those questions will galvanize techniques in direction of a writer then you definately are worse than those undesirable infantile questions.

There has never been found a single missing link from one form of life to another if it happened there would be plenty of evidence to be found. It is a fact that there is not enough evidence of evolution for it to even be considered as a theory, yet they teach it in school like it is a fact. God created the world, and the evidence is everywhere.

hahaha!!
just give it time!! with evolution it just takes time to pull a rabit out of the hat, even when there is no hat and no magician!!!
lol, so dont worry natural selection will make sure your animal get a compatible breathing system !!
hahaha

evolution takes time. there is convergent and divergent evolution. we can arrive at the same solution like say breathing using different methods. from hess' law the path taken is independent of the overall energy change!

Their lungs aren't really all that different. And they branched off from us 100s of millions of years ago...

I thought it was 'wings' that were all important.
