Hello.
A circle has no end, therefore this problem would be indeterminate. Biologically, the chicken would have developed first. This is because Gallus gallus domesticus evolved from a dinosaur family known as theropods, and the rest of genus Gallus gallus evolved from other close ancestors. Therefore, by genetic mutation, a chicken was developed and reproduced to have more favorable outcomes in offspring. Through natural selection alongside artificial selection by humans of these first chickens, the species evolved to what we know today. Therefore, biologically, the chicken developed first.
