True or false: changes on behavior can lead to adaptations over time

Answer 1

Depends on the adaptation. A change in behavior cannot select for something impressive, let's say peacock feathers, that requires the process of natural and sexual selection. But organisms can adapt to their environment, like my cat. She got into a fight with a bee and stung her face, she may adapt to this, seeing as she didn't die of an allergic reaction, and learn that bees are not for eating. Nonetheless most features that we consider "adaptive" like feet, fingers, skulls, brains, ect, are not features that evolved through behavioral adaptations.

Answer 2

The simple answer is true. As a species adapts to changes in their environment, such as the need to forage for food. As one area is depleted by the use of natural disaster a species will seek to fin another location. Adaptation to the environment for survival. These adaptations occur slowly over time as the gene mutates to increase the species chances of survival. Adaptations can vary within a species, such as the human race.

Darwin first studied the changes in plants and animal life found on the Galapagos Islands. He notices that changes in a species are due to mutation, sexual reproduction, and genetic drift. Darwin notes that species that survive pass that trait on to their offspring (Darwin 1859).

Alfred Wallace (1855) writes a paper which discusses Discusses environmental influences on the appearance of new species’ adaptations.

These adaptations can be either biological or behavioral. Hence natural selection is an impressive argument for changes in a species.
