Significance November 24th, 1859 Charles Darwin wrote this book- Origin of Species after he cam back from his voyage on the Beagle Significance This book introduced the scientific theory that populations evolve over generations through natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. November 24th, 1859 <<Go Back Home Move On>> Need Help?

Natural Selection Individuals with favorable traits are more likely to leave more offspring better suited for their environment. Also known as “Survival the fittest” Examples: The evolution of Giraffes <<Go Back Home Move On>> Need Help?

Natural selection – the survival of the “fittest.” How long necks evolved in giraffes? See Hint What would happen to the giraffes with shorter necks? Survive and make off springs Die before leave off springs <<Go Back Home Move On>> Need Help?

Common Descent A common Descent is the trait that are shared by 2 or more evolved species. ORGANISMS WHO SHARE COMMON DESCENT INDICATE THAT THEY HAVE A COMMON ANCESTOR. There is strong evidence that all living organisms on Earth are descended from ONE common ancestor. <<Go Back Home Move On>> Need Help?

Evolution A developmental process: the natural or artificially induced process by which new and different organisms develop as a result of changes in genetic material. <<Go Back Home Move On>> Need Help?

Macroevolution Microevolution & Microevolution Microevolution: small adaptations within one specie that evolved from one traits from their common ancestor. (able to interbreed) Macroevolution: Accumulative genetic changes that create a new specie which is unable to interbreed with the former specie. <<Go Back Home Move On>> Need Help?

Evidence of Evolution 1. Biogeography: Geographical distribution of species. (Example: Birds live in different islands now are having specific features that best fit with the Environment of that island) Retrieved from: http://1.bp.blogspot.com/-zCv0V0H0qe0/Tc_C98Bs5GI/AAAAAAAAAIM/gyjE28O44K8/s1600/biogeografiburung.jpg <<Go Back Home Move On>> Need Help?

Fossils are the recorder as well as part of the History. In the Picture showing here, we can put species in an order depends on the depths of their fossils. That helped scientists to collect evidence of the relations between different species. http://universe-review.ca/I10-02-Taxonomy.jpg <<Go Back Home Move On>> Need Help?

Enter the Quiz

Charles Darwin is the most famous British Naturalist Who published his work “Origin of lives ” in 1859 after he came back from his voyage around the world. Or

Next Question

The Book published by Charles Darwin in 1859 called: “The Origin of Species” Next Question

2 species that are closely observed by Charles Darwin on the Galapagos Island are Tortoise and Giraffe Or

Next Question

The two species that are observed by Charles Darwin are Tortoise and Finches Next Question

The type of bird which is better adapted to the environment will survive. Or

Next Question

According to the Evolution Theory, which states the ideas of “survival the fittest”, Birds that are better adapted to the Environment will survive and pass on their genetic information. Next Question

Finches with different shapes of beaks can’t interbreed because they have evolved differently from their common ancestor. Or

Next Question

Finches with different shapes of beaks are still able to interbreed because their variation is still within one specie. Next Question

All organisms of the same species are identical.

Next Question

There is no real identical things because each single organism has it’s own DNA serious that carry one the unique gene information and show’s one’s identification. Next Question

There is no evidence that evolution has taken place on Earth. Or

Next Question

In the science field, there are nowadays many evidence indicate the process of evolution, in which, biogeography, Fossils, taxonomy, homologous structures are the most commons evidences. Next Question

Fossils of the organisms died long time ago are the strongest evidence of Evolution
