Study Notes
Charles Darwin
- Darwin was a naturalist who sailed around the world on the HMS Beagle from 1831 to 1836
- Darwin studied finches in the Galapagos Islands and discovered that they varied from place to place because they descended from a common ancestor on the mainland
- Darwin’s observations led him to develop the theory of evolution by natural selection, which states that species that are best adapted to their environment will survive and reproduce
- Darwin’s book "On the Origin of Species" solidified him as the father of evolutionary biology
The Galapagos Islands
- Darwin spent five weeks exploring the Galapagos Archipelago
- The animals were similar to those found on mainland South America, leading Darwin to believe they came from the mainland
- The unique environment of each island determined which animals survived and reproduced, causing them to become different from their mainland relatives
Natural Selection
- Natural Selection is the process where species that are best adapted to their environment survive and reproduce
- Natural selection drives evolution
Camouflage
- Camouflage helps animals hide from predators and sneak up on prey
- There are three main types of camouflage:
- Concealing camouflage: blending in with the background
- Disruptive coloration: breaking up an organism’s color with a pattern like stripes or spots
- Mimicry: copying or imitating the form of something else
The Peppered Moth
- The peppered moth has two phenotypes: white speckled and black speckled
- Before the Industrial Revolution, the white speckled moths were more common because they blended in with the light-colored bark of trees
- After the Industrial Revolution, the black speckled moths became more common because they blended in with the soot-covered trees
- This is an example of natural selection in action, where the environment influences the survival and reproduction of a species
Natural Selection vs. Artificial Selection
- Natural Selection:
- Happens slowly over time
- Environment influences survival
- Selected trait improves an organism's fitness
- Artificial Selection:
- Happens quickly over time
- Humans influence survival
- Traits are desirable to breeders
- Decreases an organism’s fitness
Survival of the Fittest
- Survival of the fittest refers to the process of natural selection
- It does NOT mean the strongest or biggest, but rather the ability to survive and reproduce in a given environment
- This includes factors such as finding food, obtaining a mate, and securing its habitat
