Vocab• Theory (#16)- an explanation that is supported by a
large body of evidence; ex: evolution, cell theory• Law (#17)- describes a set of relationships; ex: law of
gravity• Hypothesis (#18)- an educated guess that explains
observations; testableMore than just a hunch!
Vocab
• Lethal (#38)- deadly
Lethal allele: causes death
Vocab
• Recombination (#23)- shuffling of genes in new combinations
Crossing Over:
Sexual Reproduction:
Vocab
• Evolutionary processes (#22)-– more offspring are born than can survive– individuals have variations– some individuals reproduce more than others
Inv. 9.2: Natural Selection
Notes: Adaptations
Definition
• Adaptation- a characteristic that increases an organism’s ability to survive & reproduce
• A population adapts to its environment over time
• Adaptations arise through natural selection
3 Types1. morphological adaptation- adaptive structure or body
part - ex: long tongue of anteater helps in eating ants
2. physiological adaptation- adaptive cells & body systems
- ex: platelets help blood clot
3 Types
3. behavioral adaptation- adaptive reactions to the environment - ex: mating dance of birds
3 Types
Create an Organism• Pick one item and decide how an organism would
use this appendage to help them survive either by (choose one!):
• finding food, • hiding from predators, • defending themselves or • finding a mate
• In 10 minutes your group will share your organism’s– Name – Typical habitat – How it would use the appendage (arm, leg, mouth, tail…)– What is the purpose of the appendage
