Not less evolved. Just evolved differently for alternative environmental circumstances.
There is no hierarchy of evolutionary traits. Just an amalgamation of traits that are or are not useful in the current environment. What genetic makeup is effective in one place and time is useless in another, and what was once useless may now be beneficial.
We have no clue how threatening they could potentially be.
To have “more or less” of something implies the effectiveness of the product is directly caused by the metric being measured.
The amount of time a genotype took to evolve has no bearing on the effectiveness.
There is no such thing as “more/less evolved”. There is no gradient. Something either is evolved to adapt to its environment or it isn’t.
