Since human brains and DNA are more complex it is reasonable to suspect the generational transference to be greater than in mice.
Yes, but the underlying mechanisms behind brains, neurons, cells, DNA etc. aren't going to be so different.
That’s really not always true. And it’s disingenuous to so unequivocally write the title of a paper about mice when the headline article is about humans.
The article talks about the mouse research, I'm giving a link so people can read something other than a Guardian article and judge for themselves. Fair enough mice are different to humans but they're not exactly lobsters. (Edit: although if a similar mechanism was found in lobsters I would take that as evidence the phenomenon being widespread. It's not ethically feasible to conduct this experiment on human subjects)
