"Organisms Evolve Because They Need To"
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The claim that an organism evolves a trait because it needs one reverses the mechanism: variation is filtered by survival and reproduction, not summoned by need.
Show
A bacterial population did not evolve antibiotic resistance because it needed to; resistant individuals already present survived treatment and multiplied.
Watch for
Need can explain why a trait would help, never how it first arose in the population.
