A Lesson from a Biologist Dinner Party
I was reading about a new strain of antibiotic resistant Tuberculosis in the news today…
What CAUSES antibiotic resistance anyway?
Like, What Happens??
Wait! Maybe I’ll ask my students! They’ll know!
We are all in England, drinking tea, and most likely fabulously dressed
The moth ranges in color from a light mottled gray to dark black
We love to spot the dark moths because our real joy is to see a bird swoop in and eat the moths!
The black ones are more likely to be bird-gobbled!
The factories are pumping pollution and soot into the air and our nearby moth-watching spot!
The pollution kills the lichens, and the soot covers the tree trunks.
The next Generation of Moths
Strict environmental regulations are put in place that restrict pollution and set clean air standards
What do you think is going to happen to the peppered moths?
During treatment with an antibiotic, each individual bacterium tries to become resistant to the antibiotic. Only some are able to willingly become resistant, and these individuals survive to pass this trait to their offspring.
