Some example include the deer mouse, the peppered moth, and the peacock. Bacteria are a common research subject when studying evolution and adaptation because some colonies of bacteria can produce several generations in one day, letting researchers see a "fast forward" version of evolution and natural selection.Prokaryotes have 70S ribosomes, singly made of a 30S and a 50S subunit. While the Eukaryotes have 80S ribosomes, singly made of a 40S and 60S subunit. 70S Ribosomes are relatively smaller than 80S while the 80S Ribosomes are relatively bigger than 70S ribosomes.⠀
