hypotheses

However, there are a few hypotheses.

Nuzzo said there are other hypotheses — which she stressed are just hypotheses — including one that posits people who were exposed to the H1N1 swine flu outbreak in 2009 may have acquired some immunity to the “N1” part of the virus.

“There are a lot more questions than answers at this point. So there are a lot of interesting hypotheses for why the more recent cases have been mild, there’s not enough evidence to simply discard more than two decades worth of evidence about this virus that tells us that it could be quite deadly,” said Nuzzo.

"It's fascinating and interesting and salient. We have tons of data coming in from satellites. We have improvements and understanding from the models. We have tests and evaluations and calibrations and all the things that you want in a science. We have predictions that have come true. We have hypotheses that have been tested and conclusions that have stood the test of time. It's not at all weird!"

"There are a couple hypotheses regarding the advantages of these evolutionary innovations in the bottom dwelling sea robin," Herbert said in a statement.
