“Hey DDD, men will sleep with anything? Right?🐷” Oh boy! That’s a view I’ve heard many times before. Like a lot of folk psychology, there’s a tiny kernel of truth🌽here that's blown way out of proportion. And I think I know what it is… [1/17]

First of all: There's a full spectrum of mating pickiness both sexes. Men so picky they never lose their virginity and women with unusually low standards. There’s a lot of noise and variation. Thus, we should be sceptical about neat black and white🐧claims about the sexes. [2/17]
That being said, there are often patterns to be found in the noise. Enough to draw some conclusions about the *typical* mating behaviour of each sex, but not enough to predict the behaviour of individuals with a high degree of accuracy. [3/17]
One of those patterns appears to be that more men than women “lower their standards” when it comes to sex. But, and here’s the important part, it’s in a particular context: short-term mating. [4/17]
Humans, by and large are pair-bonded mammals. From megacities to small bands of hunter gatherers, humans seek a special partner to fall in love💕and share their life with. And as far as we know, this has been the case thousands (perhaps millions) of years. [5/17]
Because of this, humans are *really* picky about their long-term mates. Both sexes! We’re not like peafowl where one sex makes the effort🦚and the other chooses. If we were, then first dates would look very different… men all dressed up and women in their pyjamas! [6/17]
No, humans are quite picky and for good reason - investing in a relationship (and maybe children) is a big commitment. We want to make sure that we’re committing to the best possible person and that they’re just as devoted to us and not wasting our time🕓. [7/17]
But, here’s the thing… long-term mating, while a popular choice, isn't the only thing on the human mating menu. We’re capable of short-term, casual mating too. A strategy which may have provided its own evolutionary benefits – benefits which differed between the sexes. [8/17]
For women, short-term mating might have served to capture the attention of a particularly desirable man – a gateway to a long-term relationship. It may have also allowed them to benefit from accessing the resources and protection of multiple men rather than just one. [9/17]
But this strategy would have been risky to sexual health and reputation, and would have left some to raise a child with no paternal investment. Thus, women evolved to use this strategy cautiously, maintaining a high level of pickiness as they did so. [10/17]
For men, short-term mating served as a way of having sex without commitment; plain and simple. A no strings attached✂️liaison might have led to him passing on his genes to future generations without the parental responsibility that usually accompanies this. [11/17]

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.


...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.


Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
