Question 2

Charles Darwin

Question 3

requirements of evolution

Answer 3

over production. competition. variation. natural selection. reproduction. speciation.

Question 4

overproduction

Answer 4

within species there are more offspring produced then possibly survive

Question 5

competition

Answer 5

organisms fight for resources (food water space) because there are more organisms than resources available, certain variations, among organisms and allow them to compete more successfully

Question 6

survival of the fittest

Answer 6

organisms best adapted to environment can generally survive

Question 7

natural selection

Answer 7

environment is an agent of natural selection determining which adaptions or variations are helpful and which are harmful

Question 8

reproduction

Answer 8

individuals with helpful variations tend to survive and reproduce

Question 9

speciation

Answer 9

development of new species occurs as variations or adaptions accumulate in a populations over many generations

Question 10

what defines a species

Answer 10

The ability to produce a fertile offspring

Question 11

sources of variation

Answer 11

differences within population result from two kinds of genetic events (recombination- of alleles during sexual reproduction (crossing over) or mutations)
