Why the Earth Has Fewer Species Than We Think

A counterpoint that suggests that his nautilus example is bunk:

Similar to the dinosaur situation [1].

I wonder what kind of error rate we have?

It's news to me that methylation is "usually unwelcome". I had gotten the idea that it was just another built in general regulation mechanism. Would it be beneficial to somehow strip off all methylation?

If anyone head always found the whole species terminology to be a little vague and lacking: check out this video by brainscoop[0].

Most explanations really fail to bridge the gap between terms like species, breeds, races, subspecies etc.

The fact that a number of different "species concepts" exist was a big eye opener.

I don't read as much biosciences as I used to but neo-lamarckism used to be a term of abuse. He's writing it non ironically as a recognised label!

Interesting, surprising and unsurprising all at once. We can all probably think of a bunch of animals that morphologically or phenotypically appear different but are the same species. An alien observer may at first glance may even think this of humans, when looking at a growth stunted person very short/skinny person (perhaps due to malnutrition or other reasons) and a morbidly obese person.

Super fascinating. It seems like there's hardly any need for DNA/gene hacking when we can probably do most of it from tinkering with epigenetics.
