But just in case, here are a few details. Like all viral diseases such as the flu, measles, rabies, or AIDS, the best thing you can do to stay safe is to avoid direct exposure to the virus. Survival of the fittest, term made famous in the fifth edition of On the Origin of Species by Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing.

Germs have shaped our evolution and made us who we are.

Fear and uncertainty about the future. It’s heartbreaking. However, natural selection is simply a description of what happens in the living world. And yet. That’s good news. It was not deliberately engineered. Grief over the loss of loved ones.

My condolences to you and your family. Is paedophilia fine because bonobo adults have sex with juveniles? Our third-best defense is antiviral drugs, which don’t exactly destroy the virus but reduce its impact and give the immune system more of a fighting chance. So far this year, over 180,000 people have died from COVID-19, including 48,000 Americans. Please refresh the page and try again.

Multicellular organisms are made up of cooperating complex cells. What has been especially difficult during this crisis is that no one in my family could be physically present with her as she declined, or gather in mourning after she passed.

For all that I’m fascinated by natural selection, I don’t want it anywhere near my family. The conditions that allowed SARS-CoV-2 to emerge aren’t going away anytime soon.

No one can plausibly argue that this justifies humans behaving in the same way. In a cold region, only those with thick, downy plumage survive and reproduce. And finally, evolution already has, almost certainly, provided us with adaptive genetic diversity to resist COVID-19. In many ways, this is what natural selection feels like. Our genetics would just mitigate the final death count. If they fly off to a region that is very hot, only the thin-feathered geese survive the heat. The immune system: can you improve your immune age? Your newsletter signup did not work out. In any case, what happens in nature does not justify people behaving in the same way.

For another thing, we don’t actually want natural selection to be making gross adjustments to our genomes. Privacy Policy and “Coronavirus” is a general term for this family of viruses.

She lived a full and successful life. We don’t have a vaccine for SARS-CoV-2, but scientists are working on it. Very well said, Jacob. For SARS-CoV-2, that means minimizing contact with people who might be infected (i.e. Cooperation is an incredibly successful survival strategy. The microbiome: How bacteria regulate your health. Most people are willingly taking on huge inconveniences just to block a disease that isn’t even a major risk to them personally.
