Q

What practice did Darwin notice by Luther Burbank and others that led Darwin to see that a similar process was happening in nature? The natural version of the process favors what kinds of plants & animals?

A

Burbank was able to create new varieties of plants to the skill with which he could pick out a dozen seedlings from several thousand. The bonfires of rejected ones testified to the degree of his selectiveness. Certain traits are selected for. Similarly Darwin starts with random variations—unexplained—and the selection of certain of them by man for the breeding of specially useful varieties or “races.” Natural selection is the same process occurring in the wild state but selects for the traits that help the plants and animals to best survive.

Q

Lamarck

A

Had famous idea of “use inheritance”. Geological evidence shows clear signs of environmental change. Animals will pass on traits that they developed in life.

First to catalogue hundreds of species of plants. He hinted the idea of development.he noted ch age in environment. He began to speak of adaptation and studied skeletons and “speculated” about common ancestry.
