Birds, unlike mammals, do not have separate exits for urine and feces. Both waste products are eliminated simultaneously through the cloaca. While mammals excrete nitrogenous wastes mostly in the form of urea, birds convert it to uric acid or guanine, which reduces water loss in comparison.
Answer:
Molecular evidence
Explanation:
Earlier archaea were considered as bacteria because they show some similarities with bacteria like binary fission as mode of reproduction, lack of a nucleus, etc.
Later Carl Woese separated bacteria in a different domain and divide prokaryote into two domains called bacteria and archaea. He separated archaea from bacteria on molecules evidence.
He compaired rRNA sequence between bacteria and archaea and observed that they both differ in rRNA sequence which allowed him to make a separate domain for archaea.
