Evolution Available Sheet that follows slideshow for classwork.

Darwin hypothesized that one finch landed on the Island.
This one finch over time and evolved into many different types of finches. Copyright © 2010 Ryan P. Murphy

Some finches have small beaks to eats small seeds,

Which Finch is better adapted to crush large seeds that fall to the ground?

Variation in Finches

They even evolved into a Vampire Finch.

Evolution is the change in the gene pool overtime.
Gene Pools can change when… Populations can shrink Diseases, extinctions, introduction of new better adapted species, predators. Non-random mating Organisms choose strongest mate, ones in similar boundaries, Mutations in the genes Genes can change. Some are good, some are bad. The environment will decide. Movement in and out of the population Immigration, gene flow. Natural selection Adaptations to the environment that do well replace poor ones. Usually an advancement.

Review Activity! The Hypotheticus Beast.

The hypotheticus is a normal animal, it eats leaves and tubers (roots).

More babies are born than can possibly survive.

Each Hypotheticus is slightly different than the other.

Predators such the Fanged Tooth Scienceteachericus kept populations of the Hypotheticus in check.

Let’s go back to the beginning

Climate in Hypotheticus Land became drastically dry for the next several years.
Many of the shrubs are eaten or start to die. Copyright © 2010 Ryan P. Murphy

Natural Resources are limited for the Normal Hypotheticus.

The normal Hypotheticus can’t reach the leaves, and there aren’t enough shrubs to survive.

Over thousands of years, the normal type Hypotheticus slowly have trouble surviving to reproduce.

The Fanged Tooth Scienceteachericus has no problems killing these tired and weaker species.

The long necked Hypotheticus tend to survive more often because they can reach leaves on trees.

With more Long Necked Hypotheticus surviving,

Overtime, nature favors the Long Necked Hypotheticus,

Overtime, nature favors the Long Necked Hypotheticus, and gradually, those offspring with longer necks survive more often to reproduce and their offspring have long necks. Copyright © 2010 Ryan P. Murphy

The clawed Hypotheticus can dig up tuber roots better than the other Hypotheticuses.

Nature favors Longer Clawed Hypotheticus, as they can reach the tubers,

Nature favors Longer Clawed Hypotheticus, as they can reach the tubers, slowly over thousands and thousands of generations, the Hypotheticus gets shorter, and gets larger claws for digging. Those that are shorter with longer claws survive more to reproduce. Their offspring are also shorter and clawed. Copyright © 2010 Ryan P. Murphy

Eventually, the two won’t mate at all.

Over hundreds of thousands to millions of years a new species has evolved.

This is called adaptive radiation. Copyright © 2010 Ryan P. Murphy

In this environment, having more hair keeps you drier and warmer in a cold climate.
The Long Haired Hypotheticus has a slightly better chance of survival. Copyright © 2010 Ryan P. Murphy

Populations of the Hairy Hypotheticus are stable in size except for some seasonal changes.

The ones that have more hair survive more and thus reproduce more.

The ones that have more hair survive more and thus reproduce more.
Because traits are passed down, more and more Hairy Hypotheticus result. Copyright © 2010 Ryan P. Murphy

The world is thrown into an ice age for 60,000 years,

The world is thrown into an ice age for 60,000 years, only the most Hairy Hypotheticus survive.

Now only really hairy hypotheticus have survived and they mate with other surviving hairy hypotheticus.

The Normal Hypotheticus went extinct,

The Normal Hypotheticus went extinct, but its existence helped evolve several species.

You can now complete this question.

This video is what we are often taught when we are young. (Not correct)
We will create a children’s story soon that explains the process according to Darwin. Shorter Version at..

Activity! You need to create a story book about your own type of unique Hypotheticus.
Please include the mechanism for change (The parts of Natural Selection from the notes). Create pictures, have fun with names. Provide text above or below the pictures. Your Hypotheticus should change into a new animal, or many animals over many thousands to millions of years. Use technology if you want, or use paper, staples, and your creative abilities. Be prepared for story time! Example next slide Copyright © 2010 Ryan P. Murphy

Todd the Tortoise By Your Name

This is the story of Todd the Tortoise and how he got his shell.

One day Tom saw the love of his life
Tina the Tortoise…

They went behind a rock and decided to start a family.

Tina laid many eggs. More were born than can possibly survive.

Natural resources are limited.

Sammy the Snake Enjoys eating tortoise eggs and baby tortoise.

Only a few of the eggs survived to hatch into baby tortoise.

No two individuals were alike and baby Todd had this weird shell on his back.

“C’mon Todd, your so slow.”
No two individuals were alike and baby Todd had this weird shell on his back. “C’mon Todd, your so slow.”

Predators such as Sammy the Snake kept populations of tortoise in check.

One day Todd meet another female turtle that had a small shell thing on her back.

They went behind a rock and decided to start a family.

Variation is inheritable and most of the offspring also had this shell.

Todd Jr. bumped into Sammy the snake one day as an adult tortoise.

Todd’s hard shell made it very difficult for Sammy to eat him.

Shelled tortoise began surviving more often and were able to reproduce.

Overtime, more shelled tortoise survived because nature selected their shell for survival.

Their offspring were also shelled. A new species was eventually born.

Their offspring were also shelled. A new species was eventually born.
“Who are you?”

Northern Peoples Fair Skin = More skin sun exposure and vitamin D production Darker skinned Equator = Darker skin better suited for increased sun Darker skin living near the poles won’t get enough vitamin D which is critical.

Northern Peoples Fair Skin = More skin sun exposure and vitamin D production Darker skinned Equator = Darker skin better suited for increased sun These differences are minor and wonderful
