Muddiest Point- PatrykS

My muddiest point is what is the difference between Lanmarks and Darwins theory

Joe M's Muddiest Point

I'm confused about how genetic drift works. What is the concept of it?

Muddiest Point

I kind of do not understand what co evolution and convergent evolution are.

Muddiest Point

I do not understand the "similarities of embryos, homologous structures, vestigal structures, and biochemical similarities"

GabbyM's Muddiest Point

My muddiest point for this chapter is the difference between relative and absolute dating.

Muddiest Point

The thing that i am most confused about is the difference between Darwin and Lamark's theories.

Today we went over and Reviewed Evolution and Half Lifes!

To review half lifes we answered a question on page 29 of our unit packet (question B) this is also a great source of reviewing for Half life problems for the test on thursday! We then went over some class notes which then led us to beginning and almost finishing our labs in which we had to measure an compare the Jaw width and the Diameter of the brain capacity of a 1.Gorilla 2. Australopithicus (Lucy from the bio day movie) 3. Human. While doing the lab we had to fill out one of the pages between 42-47 that asked us to compare all of the 3 skull structures. After that you had to compare the Jaws with the teeth and the animals pelvis's. The data helped us understand and compare how each kind of organism that developed from that one ancestor that connected apes and humans.

Homework-

1. Finish Up 42-47

2. Read 26.3 with Cornel Notes or Check My Understanding Strategy.

SCRIBE POST!!!!!!!!!

Today in class we talked a lot about Half Lifes.

Which is the time period it takes for a certain substance to decay by half.

We also went over a few half life problems which i was struggling with a lot and so were others in the Class.

To help incorporate our lesson with half lifes we did an M&M lab---------------->

in which we had to count out 100 M&M's and then place them into a cup and shake for 10 seconds and pour the M&M's into the paper plate and all the M&Ms with the M facing up were to be eaten and then we would repeat the process shaking the M&Ms and adding 10 seconds onto each time we shook the container. After we finished with the lab we were given the right to eat the M&Ms and then begin working on the

HOMEWORK-

Finish UP 31-32 Use LINE GRAPH! NOT BAR GRAPH!

My muddiest point is on the difference between Darwin and Lamarks theories.

Muddiest point

My muddiest point is what the differances between darwin and lamarks theries were?

Muddiest Point 2/7

My muddiest point is all about Darwin. What was his theory? What is the concept of "survival of the fittest" and "descent with modification?" I am kind of confused with those.

Thanks,
Jessie

Muddiest Point- Sammy K

How does Photosynthesis and aerobic respiration have an impact on the process of evolution?

Muddiest Point

My muddiest point is the difference between punctuated equilibrium and gradualism. I don't understand the difference between them, and the difference between their graphs.

Muddiest Point

My muddiest point in this unit is understanding why the anthropoids and the hominoids are two separate classes, since they are both primates. Can someone please explain?

Thanks!

Today in class we reviewed Darwin and Lamarck in UP 13.

Question 1 - Mutations and genetic recombination are responsible for variations among offspring. Answer: neither, because no body knew about DNA at this time.

Question 2 - There is a struggle for existence among organisms. Answer: Darwin only because he believed that organisms compete and only the fittest will survive.

Question 3 - Modern giraffes are descendants of short-necked ancestors. Answer: Lamarck only because he believed in acquired characteristics.

Question 4 - Two mice whose tails hab been cut off should produce offspring with no tails. Answer: Lamarck only

Question 5 - There is a tendency towards overproduction in nature. Answer: Darwin only because the species overproduce to make sure they pass down their genes.

Question 8 - If you lift weights, your children will be born with strong muscles. Answer: Lamarck only.

Question 14 - All organisms have an inborn urge to better themselves and become more fit for their environment; thus birds developed wings because of this urge. Answer: Lamarck.

We also completed Lab 38, which was based on eveidence for evolution. There was questions about vestigial structures, comparative embryology, and we also colored a picture of different animals bones.

Homework:
1) READ 19.1 (Skip Pages 544 and 545).
2) Unit Packet 33-36
3) TV Ad on FEB 28

Today in class we first looked over pages 33-36 in our unit packet. Afterwards we watched a Bill Nye Video and learned that:

• Contents of the clay in KT has Iridium which is something only found in space (this is evidence that there was an asteroid which had hit earth in the past).
• That an asteroid made all living creatures on earth perish (dinosaurs, etc.)
• The asteroid was said to be 8 times bigger than the grand canyon.
• A man made an experiment where he took a chamber that had gasses which were used back in time and then placed energies into it which created amino acids. (this shows that this may of been the reason how life was created).

SCRIBE 2/1

Today in class we started off by taking notes on genetic variation, genetic drift, and speciation. genetic drift is changes in the gene pool of a small population due to chance.

We then learned about variation in Grasshopper legs by working on Lab 40. With our lab groups, we were asked to measure the length of 5 grasshoppers' femurs. This data was then used to find the average femur length from all the grasshoppers. The different lengths of femurs represent variation-a change in gene frequency.

The homework for tonight is to finish lab 40, read 19.2, and the T.V. ad that is due on feb. 28.

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!!!

gliese 581g

After 11 years of NASA research a red dwarf star, gliese 581g has been looked at a lot closer and it is pretty much another Earth. After looking at pictures of it I thought it was just a picture of Earth but it's not.
This planet is not freezing like all the planets past mars that range from -200 through -400 degrees. And it is not hot like Venus and Mercury that are in the 800's.
It has been said that Mars has dry river beds and other dried up bodies of water which once supported life. The only water on Mars is frozen from the cold which at its lowest is -190 degrees.

On gliese 581g an atmosphere is capable of being held because the gravity is strong enough, but the star that would be this planets "Sun" does not get circled like Earth does to the Sun. Because of that, the lighted side of this planet will always be the lighted side and the dark side will stay dark. If we were to live on this planet we would have to be on the border so we don't freeze or burn but stay at a decent temperature.

Here's a more detailed article from NASA about this http://www.nasa.gov/topics/universe/features/gliese_581_feature.html
This could be interesting if we lived there but it is 20 light years away. so if we traveled at the speed of light for 20 years then there we go.


I'm excited about...
Passing this class and getting it over with.

I'm not excited about...
Having to do work.
