Charles Darwin?
A English Naturalist who discovered that natural selection was the agent for the transmutation of organisms during evolution. "Origin in species."

Charles Darwin credits
- Natural selection
- Discovering the common ancestors in different species
- Transmutation in naturalization
- Many Books
- "Origin of Species"
Charles Darwin is given credit for a lot of things but here are just a few:
Natural Selection
Discovering the common ancestors in different species
Transmutation in naturalization
Different species in different islands: such as the Galapagos Islands.
Natural Selection
Discovering the common ancestors in different species
Transmutation in naturalization
Different species in different islands: such as the Galapagos Islands.
Voyage
- 535 days at sea
- 1200 days on land
- Lasted 5 years
- Supposed to last 2 years
- Different species in different parts of an island
535 Days at sea, 1200 days on land. Accurate identification of living organisms required systematics accessible only in London and Paris.
Observations
- Different species on different island
- Fewer inhabitants
- Discovered a section of strata across South America
- Different between species of birds and animals on the Galapagos Islands
- Smaller species hid within bigger species
Natural Selection
- Over population
- Constancy in numbers
- Variation in traits in between same species
- Survival of the fittest
- Struggle to survive
Macro-evolution: how species evolve. Natural Selection is quit simple. But there is not enough food for all the offspring so not all survive. Certain characteristics that give the survivors an edge: like Speed and Strength but some weak survive if they are mart enough.
EVIdence Of Evolution
- Growing population
- Same traits in different species
- Common ancestors
- Survival of different specis
- Different species in different habitats
Environmental effects over time
- Environment changes
- Some species adapt
- Some species dont
- Pass genes to their offspring
- If the generation before survived
Different types of seletion
- Stabilizing Selection
- Disruptive Selection
- Directional Selction
Tortoise differences
- Live on Land
- Plastron is the lower portion
- Carapace is the upper portion
- Shy in nature
