“What keeps me up at night is that another coronavirus like MERS, which has a much, much higher mortality rate, becomes as transmissible as COVID,” said Christian Walzer, executive director of health at the Wildlife Conservation Society.

They fear another virus will leap from wildlife into humans, one that is far more lethal but spreads as easily as SARS-CoV-2, the strain of coronavirus that causes COVID-19.

Octopus And Squid Evolution Is Officially Stranger Than We Could Have Ever Imagined

Just when we thought octopuses couldn t be any weirder, it turns out that they and their cephalopod brethren evolve differently from nearly every other organism on the planet.
In a surprising twist, in April 2017 scientists discovered that octopuses, along with some squid and cuttlefish species, routinely edit their RNA (ribonucleic acid) sequences to adapt to their environment.
This is weird because that s really not how adaptations usually happen in multicellular animals. When an organism changes in some fundamental way, it typically starts with a genetic mutation - a change to the DNA.
