EVOLUTION, DARWINNatural Selection
S.W.B.A.T.: Determine that what Darwin viewed in nature about the traits of living things helps organisms even today survive and adapt to their
surroundings.

What Did Darwin’s Travels Reveal
• The diversity of living species was far greater than anyone had previously known
• These observations led him to develop the Theory of Evolution

How did tortoises and birds differ among the islands of the
Galapagos?
• Each island
had its own type
of tortoises
and birds that
were clearly
different from
other islands

Natural Selection
• The traits that help an organism survive in a particular environment are “selected” in natural selection

Evolution is when organisms change over time
So, modern organisms descended from ancient ones

Evidence of EvolutionReview
• Fossil Record provides evidence that living things have evolved
• Fossils show the history of life on earth and how different groups of organisms have changed over time

Vestigial OrgansEvidence of Evolution
• Organ that serves no useful function
• Present day organisms evolved from ancestors in which these organs were useful
![Page 17: EVOLUTION, DARWIN Natural Selection S.W.B.A.T.: Determine that what Darwin viewed in nature about the traits of living things helps organisms even today.](https://reader035.fdocuments.in/reader035/viewer/2022062718/56649e705503460f94b6ebe2/html5/thumbnails/17.jpg)
Biochemical Evidence• All living organisms are made of the same
20 common amino acids
• All living organisms have DNA as the code of life with the same 4 bases: adenine, thymine, cytosine, guanine

Homologous StructureEvidence of Evolution
• Body parts that are similar in structure in different organisms and seem to have developed from the zygote the same way
• Homologs may have different uses in different species
![Page 19: EVOLUTION, DARWIN Natural Selection S.W.B.A.T.: Determine that what Darwin viewed in nature about the traits of living things helps organisms even today.](https://reader035.fdocuments.in/reader035/viewer/2022062718/56649e705503460f94b6ebe2/html5/thumbnails/19.jpg)
Similar EmbryosEvidence of Evolution
• In their early stages of development, chickens, turtles and rats look similar, providing evidence that they shared a common ancestry.
