Learning objective

Changes Over Time

Learning Objective

Students will explain how natural selection leads to evolution.


Origin of species
Origin of Species

  • 12.) In his book The Origin of Species, Darwin explained that evolution occurs by means of ______________.


Origin of species1
Origin of Species

  • 12.) In his book The Origin of Species, Darwin explained that evolution occurs by means of natural selection.


Natural selection1
Natural Selection

  • 13.)Individuals that are better adapted to their environment, or have variations, are more likely to survive and reproduce than other members of the same species.

False


Natural selection2

Changes Over Time

Natural Selection

  • 14.) The effect caused by limited food and other resources is called competition.


Natural selection3

Changes Over Time

Natural Selection

  • 15.) Differences between individuals of the same species are called variations.


Natural selection4
Natural Selection

  • 16.) The effect caused by a species production more offspring than can survive is called overproduction.


Genes and natural selection
Genes and Natural Selection

  • Genes are passed from parents to their offspring.

  • 17.) Because of this, only traits that are controlled by genes can be acted upon by natural selection.

True


Genes and natural selection1
Genes and Natural Selection

  • 18.) Darwin could not explain what caused variations or how they were passed on.

False

?


Genes and natural selection2
Genes and Natural Selection

  • Genetic variation contributes to evolution.

  • Without variations, all members of a species would have the same traits.


Genes and natural selection3
Genes and Natural Selection

  • Genetic variation contributes to evolution.

  • Without variations, all members of a species would have the same traits.

  • 19.) Natural selection would not occur because all individuals would have an equal chance of surviving and reproducing.


Natural selection comic strip
Natural Selection Comic Strip

  • Look at the pictures of the turtles on pages 229 – 231 of the textbook.

  • Label each box with the 5 different factors of Natural Selection: Overproduction, Variation, Competition, Selection, Survival and Reproduction.

  • Draw a picture depicting each of these factors. You may use the sea turtles or another example of animal if you choose.

  • Color the pictures for extra credit.


Glue in snb
Glue in SNB

**Please remember to use only TWO drops of glue!!**

If everyone uses only TWO drops, a lot of glue is saved over time….
