ARTIFICIAL SELECTION

2 Occurs when people (not nature) select individuals with desirable traits to mate and produce offspring with these traits This is also called selective breeding.

5 Dogs are parts of a single species There are over 400 different breeds of dogs A breed is a subspecies. It takes many generations to get a new breed Many breeds today are a result of artificial selection/selective breeding Introduction

EXAMPLE TO SHOW ARTIFICIAL SELECTION years ago there was no such thing as a foxhound! How did they get here?

7 English fox hound X French hound Great speed Excellent smell How to Get an American Foxhound and Why

American fox hound which is an excellent hunter with great speed and excellent sense of smell The Result of the crossing

AN EXAMPLE OF A CROP SPECIES Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.artificial selection

SIMILARITIES BETWEEN NATURAL SELECTION AND ARTIFICIAL SELECTION Both require: Variation of trait Inheritability of the trait Selection of some individuals to breed and not others Change in the traits of generations.
