Love or Perish
This essay is about an aphorism that a great teacher morrie swartz created. This asphorism is called "Love or Perish". I will explain in my piont of view what was meant by this, to start; followed by the goods that come of believening in it. Lastly i will explain the bad things that come of this if you believe in it.
I believe when morrie said," We must Love or Perish" he meant that we need to feel love to exist. Not only love but that we need one another to help eachother in our time in need. This is because we need someone to look after us when were little and again when were old. In the middle though you need people as well to do help u coop with feelings and to guide you. that is what morrie meant by we must love or perish.
The good things that come from following this asphorism is that you get closer to the ones you love and that is a very powerful thing. this is because you need them because they are all you have at times. Like when you someone too talk to they are always there for you. That is why you you need to believe in Morrie's aphorism; but, there is some bad things that com efrom believening in it.
The bad things that come from believening in love or parish are that you forget about ambitions towards money and work. this is because you will start to focus more on the people in your life and less on your job. this can then end with you not caring about your job and you can lose it. that is how believening in love or parish can be bad.
In conclusion, you must take the good but watch for the bad when believening in the aphorism. The way you can is just create your own culture with it, as Morrie did. I then finish with believe in it but not to much.

4.4 million years old
earliest human known
4 feet tall
enviroment was woodland
flat-footed but walked on two legs
had opposible big toes and thumbs but was better on ground
scientist thought to believe they lived in groups that helped each other and shared
canine teeth were present
weighed 110 pounds
feet more stable then that of a chimps
Riddle of the bones
How did They move?
First Family Broad heels- could withstand the pressure used in upright walking.
First Family Toe Bones- curve away from the heel , which is not like those a normal tree climbing primate.
Lucy's pelvis-hints she walked on 2 legs. looks similar to that of a modern day female.
Lucy's Forearm- Longer more power full. made so she could climb and spend most time in trees.
Laetoli Footprints- made by two feet but in a forward motion not as a chimp which is sideways.
What did they look like?
First family- vary in sizes from male to female to young
-jaw shows a mix of human and chimp-like traits
Hadar Skull- heavy brow structure with a small skull cavity and canine teeth. a more ape like looking skull.
- teeth with heavy wear from ripping vegetation off of branches
Lucy-wide pelvic opening which meant she was female
- roughly three and a half feet tall and built powerfully
-jaws shows she had wisdom teeth but no wear on her teeth so she was a middle-aged adult
Laetoli footprints-arched with a disconnected big toe
Are they all the same species?
First Family- similar structure to all and size varied
Hadar skull- fragments in jaw and teeth both similar to Lucy and First Family
Lucy- a more V shaped jaw from the hadar skull and a foot shorter then the family
Laetoli Footprints- must of had knee joints and hip joints like much of the first family and Lucy
When did they live?
First family- 3.2 Million years
Hadar Skull- 3 million years
Lucy- 3.2 Million years
Laetoli footprints- 3.6 million years

Selectively bred milking cows
These cows were bred to do one thing only to have a calve and produce up to 20 litres of milk in stead of just 2
They do this by artifical insemination, which is injecting the cow itself with genetically modifidy sperm so that calf produces more milk them usual.
This takes place on many dairy farms and labs across the globe.
the people that do this are the farmers that need to meet the worlds high demand for milk/diary products.
this process started in russia in the later 19th century and in the early 20th century.
Adaptations-1)the redish change of color in their fur.
2)the ability to swim better
3)ability to fish/ be patient
Types of Adaptations- 1)Structural because it cahnges the physical feature
2)Behavioral because it must it must do this because of its environment
3)Behavioral because it learns this because of its enviroment
How it is better- 1) Because it allows it to blend into its suroundings more
2) Because it allows them to move from island to island with in the habitat
3)Because this allows it to obtain a food source during the spawning season
