Question

 QUESTION 9

 The contribution of Alfred Russel Wallace to our understanding of evolution was that:

 species are immutable

 individuals acquire tralts that can be passed on to their offspring

 the mechanism of evolution is natural selection

 recessive alleles remain in the population at their same frequency from generation to generation unless evolution is occurring

 "in sexually-reproducing species, males and females both contribute genetic material to the offspring that is maintained in the offspring, even though it may be directly expressed"

 QUESTION 10

 The contribution of Charles Darwin to our understanding of evolution was that:

 species are immutable

 individuals acquire traits that can be passed on to their offspring

 the mechanism of evolution is natural selection

 recessive alleles remain in the population at their same frequency from generation to generation unless evolution is occurring

 "in sexually-reproducing species, males and females both contribute genetic material to the offspring that is maintained in the offspring, even though it may be directly expressed"

Answer 1

According to the Alfred Russell wallace to the understanding of evolution individuals acquire traits that can be passed on to there offsprings . According to the Alfred the environemntal changes are responsible for driving the evolution . The changes in the environment is potent force on the evolution . There are various mutation and changes in the inheritable genetic material of a species which leads to the development of various new characters which are passed on to the next generation .

Hence option 2 is the correct answer .

10) the contribution of charles darwin to our understanding of evolution was that the mechanism of evolution is natural selection . The nature selects the best of the character or trait that is most fittest to be able to survive in the changing environment . According to the darwin , the intraspecific competition in a limited resources area leads to the development of new characters or traits that nature selects and the organism possesssing those characters is the fittest organism .

Hence option 3 is correct answer.
