Question

Over time, data that support the successful

evolution of a species would include observations
that describe
(1) an increase in the genetic changes occurring
in body cells
(2) a decrease in the genetic variety carried in
sex cells
(3) an increase in the proportion of offspring
that have favorable characteristics
(4) a decrease in the proportion of the population
that has beneficial traits

Answer 1

NOT:

(2) a decrease in the genetic variety carried in
sex cells
(4) a decrease in the proportion of the population
that has beneficial traits

Answer 2

Evolution can be defined as the heritable changes occurring in the populations over the time through the successive generations. The process of evolution is helped by the natural selection of the favorable traits and the elimination of the unfit traits from the environment. An increased proportion of favorable characteristics in the offspring will show the proof of successful evolution.

Hence, the correct answer is 'option 3 - an increase in the proportion of offspring with favorable characteristics'.
