Which of the following statements about biological evolution is False?

a. populations evolve


b. individuals evolve


c. evolution evolves a change of frequency of alleles in the gene pool


d. an entire species can evolve Which of the following statements about biological evolution is False?
B, individuals don't go under a change in one lifetime. Rather evolution is a process that involves a long time with small changes to each offspring.Which of the following statements about biological evolution is False?
True C - alleles are the competing genetic sequences (genes) for each loci on the chromosome. If the phenotypical effect (resultant change in behaviour, structure, etc) of a particular allele gives advantage to the individual in being able to reproduce then the frequency of that sequence will increase over time within the gene pool.


True B - Phenotypical effects are expressed in individuals.


True A - Individuals make up a population


False D - whole species don't evolve, but rather diverge (branching evolution) giving rise to daughter species (e.g. Lions and Tigers share a common ancestor)






Evolution is by defintion the theory that species change over time...





b,c,d fit this...





a to me does not fit, so a is false.
b. an individual cannot evolve. example suddenly growing webbed feet
B.


This is reality, not pokemon.



B
I think b.
