What is the problem with acquired characteristics?
Ans: •The needs of an individual are not encoded in the
genome of germ cells
•Therefore they can't be inherited
What is the problem with the Ladder of Progress?
Ans: 1.) To evolution, there is only now. The idea of a direction
or concept of the future or increasing complexity is wrong.
2.)The idea that primitive/basal organisms are less evolved or
less perfect assumes that selection favors organisms that are
pleasing to humans rather than best adapted to their time and
place.

have allowed for the diversity of life at the pace Darwin
suggested

this predicts a reduction in variation through successive
generations of blending
