Some of us have ancestors only from nearby, and others have family roots further afield. How many continents does your tree encompass?
Wired magazine posted an article a couple of days ago stating that “the kangaroo’s twisted marsupial family tree is now in order thanks to jumping genes”.
Now by jumping genes we don’t mean the genes that help make the kangaroo jump.
Rather, jumping genes are genes that reproduce then insert themselves into the chromosomes at new locations. As a result, these jumping genes create mutations in the DNA that can then go on to create new branches of family trees.
