Where did Charles Darwin visited in 1800s?
Galápagos Islands
Who visited the Galápagos Islands?
Charles Darwin (naturalist)
When did Charles Darwin visited the Galápagos Islands?
In 1800s
Galápagos is a group of ______ about _______ off the coast of ______
- islands
- 600 miles
- Ecuador
What did Darwin observed in the Galápagos Islands?
Many birds called Finches
What did Darwin noticed about the Finches?
He noticed that some species of finches were more similar to others in terms of their physical traits and behaviors
“closely related” meaning
Means that they share a recent common ancestor
Explain what it means for two species to share a recent common ancestor
- When two species share a recent common ancestor, it means that they both descended from a single ancestral species relatively recently in evolutionary terms. This common ancestor is an organism from which both species evolved through a process called speciation
- Similarities in the physical and behavioral traits
Living longer
Survival
Having more offspring
Reproduction
It is a factor that affect an individual’s chance of survival or reproduction in its environment
Selective Pressure
It is a graph that represents a finch’s song as a pattern of sound frequencies
Spectogram
Other way to determine the evolutionary relationships among different species (finch)
Genetic Evidence (DNA)
