BEST OF BREED. “Alu elements have been twice as successful as L1 TEs in producing copies of themselves (1.4-2 million vs 850,000 copies), even though LINE-1 is a much older TE, in terms of evolution (150 million years vs 65-80 million years). This makes the Alu element “the most successful copier” in mammalian history.”
