<span>C Rodents and rabbits are most closely related to primates. </span>
I would say that the fishes exhibited the greatest diversity (though the brachiopods also had considerable diversity) and mostly were of the ostracoderms (with a platey or shell-like skin and no jawbone) which exhibited many varieties and also the placoderm which had gills, a jawbone and fins so was developing characteristics of modern fish.
Answer:
Kidneys
Explanation:
The kidneys remove wastes and excess water in the body through the urine, as urine flows from the kidneys to the bladder through two thin tubes located on both sides of the bladder called the ureter, and the bladder stores urine, and each of the kidneys consists of about one million filtering units called the renal tubular unit contains Each renal tubular unit has a filter called the glomerulus and tubule, and the renal tubular unit operates through a two-step process:
glomerulus: filters blood.
Tubule: Returns the necessary substances to the blood and removes waste.
Phylogenetic
Scientist use a phylogenetic tree to track the evolutionary history of a species.
