Catalyst Imagine you and the rest of the class are EXTREMELY hungry and BROKE. Your favorite food is being sold outside and you really want to buy something to eat. Ms. Adabale places a dollar in the middle of the room. What are some physical advantages you could have that would get you to the dollar first? Get creative!

Unit 5: Evolution What is evolution?
Unit 5: Evolution Evolution: the process of biological change by which descendants come to differ from their ancestors Draw a representation of what this means to you on the front flap of your flip book. You have 3 minutes. Go!

Principles of Evolution Occurs within a species Species: A group of organisms so similar to one another that they can reproduce and have fertile offspring
Principles of Evolution There is a natural variation within populations Variation: the difference in physical traits of an individual from the others in the group to which it belongs Population: all the individuals of a species that live in an area

Artificial Selection Process by which humans change a species by breeding it for certain traits
Natural Selection Mechanism by which individuals that have inherited beneficial adaptations produce more offspring an average than do other individuals AKA “Survival of the Fittest”
Fit: being able to survive and produce more offspring relative to other members of the population in a given environment
Just to be clear… Evolution = change Natural Selection = Darwin’s explanation of how this happened
5 Principles of Natural Selection VISTA Variation Inheritance Selection Time Adaptation

Connections Variation: the difference in the physical traits of an individual from the others in the group to which it belongs
Connections Inheritance: passing traits down to offspring
Connections Selection: competition for resources causes certain genotypes to be favorable over others
Connections Time: changes take time and many generations
Connections Adaptation: results in more offspring with the favorable trait
