Aretrotransposon known as alu1 is about 300 base pairs in length and is present in the human genome in about 1 million copies. approximately what percentage of the human genome is accounted for by this transposon?

As noted in the illustration, homo heidelbergensis was a tall, muscular hunter, who used both tools and weapons. because h. heidelbergensis was not a gatherer/forager, but ate a varied diet including meat and fish, we would expect to see what anatomical changes?
