Question

. all of the following are correct about evolution except:
marks : 1.00

a. geographic isolation can cause
the formation of new species.

c. if the environment changes
suddenly and an organism is not
adapted for the new environment,
it might die.

d. new combinations of alleles can
produce new phenotypes.

e. single individuals, not
populations, can change in
response to a changing
environment.

b. the best-adapted organisms

Explanation:

• Option A: Geographic isolation can lead to allopatric speciation as populations diverge, so this is correct about evolution.
• Option C: Organisms not adapted to new environments may die (natural selection), which is a key part of evolution, so this is correct.
• Option D: New allele combinations (e.g., via recombination) can create new phenotypes, contributing to evolution, so this is correct.
• Option E: Evolution occurs at the population level (changes in allele frequencies over time), not in single individuals (individuals can acclimate but not evolve in the genetic sense), so this is incorrect about evolution.
• (Note: Option B is cut off but from the start, it likely relates to natural selection and would be correct.)

Answer:

E. Single individuals, not populations, can change in response to a changing environment.
