What did Darwin notice about life on the Galápagos Islands?

Answers

Because of the isolation of Galapagos, the life forms that had somehow reached the island, such as the lizard and other such creatures, had evolved differently over time compared to their cousins on the mainland. Things like a bird that was usually able to fly no longer had long wings spans or the ability to fly on the island, the large lizards on the island were used to eating sea-vegetation and often swam right into the ocean using their long tails to swim. And so forth.

Darwin found that all the plant life and animals on the island developed from isolation. Each of these species were also different form the other species on the islands surrounding the Galapagos islands. Darwin could only explain these characteristics through a gradual transformation of the various species.

Glen is attempting to use operant conditioning to train his dog, Thor, to fetch a ball upon command. To test Thor’s understanding, Glen throws the ball and yells, “Pineapple!” Thor does not fetch the ball. Which process of operant conditioning has Thor demonstrated?

Answers

Glen throws the ball and yells, “Pineapple!” Thor does not fetch the ball.

Here, the process of operant conditioning that Thor has demonstrated is- stimuli discrimination.

A stimuli or stimulus discrimination is a behavior which results in one consequence in a particular setting and another consequence in other settings.

Thor demonstrated a stimulus generalization for its operant conditioning. Stimulus generalization occurs when there are repeated stimuli resulting to similar responses. In the situation, the operant conditioning gave a stimulus for Thor to respond on the same way but when Glen yells "Pineapple!" then his dog did not respond because it is not the same as the previous stimulus.
