Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
This is like a humans vs organisms in nature. Consider what makes humans different from any other living organism.
Factors that control human population growth:
food
shelter
goods
water
disease
health
relationships
Factors that control nature population growth:
- food
- shelter
- precipitation
- relationships
- food web
- weather ( natural disasters)
So as you can see humans pretty much has more control over our population growth while nature operates by cycle and a set of systems that man can't create, but can manipulate.
