Answer:
78
Explanation:
Chickens have 78 chromosomes. They inherit 39 from each parent, therefore a zygote (which is made up of an egg and a sperm, each a haploid gamete with 39 chromosomes) will have 78 chromosomes.
This is more than humans: we have 46 chromosomes, as we inherit 23 from each parent.
Walking upright.
You can make a case for all of them, but for three of them indirectly.
But the answer, I think, is walking upright.
You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.
Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.
I hope that helps.
