Which of the following would describe Lamarck's ideas about evolution? Horses and zebras are similar. They have a common ancestor.

A mouse loses its tail in a fight. Its offspring will not have tails.

Wolves eat most of the rabbits in a field. A few smart rabbits find hiding places. They survive and reproduce.

The second statement: 'A mouse loses its tail in a fight. Its offspring will not have tails' best describes Lamarck’s ideas on evolution. Lamarck believed that traits developed during an individuals lifetime would be passed on to the individuals offspring. This is on contrast to Darwin's theory of Natural Selection: Individuals with a competitive edge within a population are more likely to survive and reproduce, thereby passing their genes explaining that particular phenotype to the next generation.
