Natural Selection
What is Natural Selection?
Natural Selection is the process by which organisms with traits better suited to their enviorment
What are the 2 mechanisms in variation?
Differential Survival and Differential Reproduction
What does it show?
Evolutionary relationships between organisms
What type of Characteristic does Adaption have?
Heritable Characteristic
What are Sediments?
Sediments are any loose material that gets broken away and carried
Natural Selection helps with?
Reproduction and Survival
What is Artificial Selection?
choosing to breed organisms with desirable traits
Cladogram's are also known as..
Trees/phylogenies
What is Adaptation?
The evolutionary process by which organisms develop traits that enhance their survival and reproduction in a specific environment, resulting in a better fit to their surroundings.
What are Fossil Layers?
Fossil layers are fossils that formed in sedimentary rock.
What is the key mechanism of Natural Selection?
Evolution
What is Variation?
Variation implies changes in the gene pool of a population, enlarging the genetic variability from which natural selection can choose.
What are cladogram's?
A cladogram is a diagram that shows evolutionary relationships between organisms based on shared traits.
Adaptation is the biological..
Mechanism
What is Sedimentary rock?
Sedimentary rock is rock that is formed in layers by the depositing and pressing of sediments on top of each other.
Does Natural Selection adapt to its environment
YES
What are the 2 sources of Variations?
Mutations and Genetic Recombination
What is a common ancestor?
An ancestral group of organisms that is shared by multiple lineages
Adaptation helps..
Survival and reproduction
How do you know if Fossils are old?
Whatever fossil is at the bottom of the sequence of rocks is the earliest or oldest.
What are some examples of Natural Selection?
"Peppered moths evolving to become darker in color in polluted areas"
Variation Leads to..
Evolutionary Change
What is it based on?
Observable physical characteristics
3 Types of adaptations
Behavioral
Physiological
Structural
Name 4 types of Fossils
Body, Molecular, Trace & Carbon Fossil.
