Scribe

2nd Semester just started and we are starting a unit on EVOLUTION.

Homework is to Read 16.1-16.3 (pgs. 450-464) and do a double bubble "Darwin vs. Lamark". Also visit Mrs. Stein for a homework pass but read the reflection questions she posted first so you know what to talk about.

We went over things we knew about Evolution and made this list:

-Time of Change

-Adaptation to enviroment

-Changes/Transformation

-"Apes turn into People" --> False

-How Humanity got to where it is today

-Pangea --> landmass of all the continents

-Charles Darwin

-"Proved" --> it is a theory, cannot be proved

-Galapagos- origin of understanding of evolution

-migration

-SURVIVAL OF THE FITTEST

Evolution: Change in a species over time

EVERYTHING SHARES A COMMON ANCESTOR!

In class we started watching a video on Darwins voyage to the Galapagos Islands which are the tips of volcanos coming through the water.

We had four questions to answer.

What did Darwin observe on his voyage?

-In 1822 darwin went to the Galapagos for 20 years.

-He came to the conclusion that living things are shaped by the world around them.

-He saw Giant Turltes, Hummingbirds, Plants, Iguanas, Finches, and many more.

-He noticed that the same animals on each of the different islands which are pretty close together have different fundamental characteristics; Turtles had different shaped shells, birds had different beaks and colors.

What is Natural Selection?

-The process that animals are able to adapt and have different abilities and characteristics which suit them better for their environment.

How did the story of the Finches Beaks illustrate Natural Selection?

-It showed how each Finch from a different island had different beaks specifically for their island. some had beaks to dig better, crack nuts better, eat certain foods better.

It shows how they adapted to perform better in the places they are in most.

How did iguanas illustrate Natural Selection?

We did not finish the video so we will continue it tommorow. I am guessing iguanas adapted their skin colors.

JACK WILL BE OUR NEXT SCRIBE!!!
