I'm getting seriously confused.
Where do they say these are in the same position on the various chromosomes?
Thanks
That is his intention.
I think they were surprised because they found a new element.
Different organisms have different chromosomes and "ervs" are never at the same position on chromosomes.
It's OK if you want to not understand chromosomal structure or the nature of repeat elements.
Terms such as "exact same place" and the like are not accurate and are simplifications made for discussion outside technical circles.
