No. The BBC article you quoted says nothing of the sort. it says "the reproductive patterns are built around inbreeding". They follow that with: "as soon as the females hatch, their brothers impregnate them. Charming…
A limited gene pool in a species can, unsurprisingly, have a negative impact. This is known as Inbreeding Depression and refers to a population decrease due to lack of healthy mates."
British royalty had a "reproductive pattern" of inbreeding. That didn't mean it made them stronger. Ever heard of hemophelia?
And that's not an answer to the gas question. It's a sidestep avoidance
You have complained about the cost of gas rising. You seem to think that you paid $1.89/ gallon the whole time Trump was in office, because you did not mention that the price of gas started to rise immediately after he took office, and that it went form $2.14 to $2.72, a 27% increase
It's increased 31% under Biden (a difference of about two cents between increases).
What do you feel is the proper/correct baseline price of gas? Pick a grade or tell all.
What is the proper/correct percentage of annual income that we should have to spend on gas?
