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.

The answer is
"Ecology".<span>As various other researchers, Ecologists, regularly utilize
models to help comprehend complex issues. Ecological systems are frequently
demonstrated utilizing PC simulation. PC simulations can consolidate a wide
range of factors and their effects. This is one reason they are valuable for modeling
ecology. PC simulations are likewise working models, so they can demonstrate
what may occur in ecosystem after some time. For instance, simulations of
global warming have been utilized to make expectations about future
atmospheres. And field study is the key element to investigate ecological
systems based on which at times are prepared the computer simulations.</span>
