where did the term dirty bird come from
Jamal Anderson He was well known for his "Dirty Bird" touchdown celebration, in which he flapped his arms as if they were wings and rhythmically bouncing side-to-side in the crowd's direction. The dance has been widely copied; in a press conference Anderson stated: “people break out and do the Dirty Bird in the strangest places.”[2]
Chicken or the egg If the question refers to chicken eggs specifically, the answer is still the egg,[7] but the explanation is more complicated. The process by which the chicken arose through the interbreeding and domestication of multiple species of wild jungle fowl is poorly understood, and the point at which this evolving organism became a chicken is a somewhat arbitrary distinction. Whatever criteria one chooses, an animal nearly identical to the modern chicken (i.e., a proto-chicken) laid a fertilized egg that had DNA identical to the modern chicken (due to mutations in the mother's ovum, the father's sperm, or the fertilised zygote).[8][4][9][10] Put more simply by Neil deGrasse Tyson: "Which came first: the chicken or the egg? The egg â€” laid by a bird that was not a chicken."[11]
