Thomas Malthus Check out this link. Who was Thomas Malthus and what was his connection to our friend Charles Darwin?

Malthus was concerned with humans overrunning the Earth before Darwin observed animals' carrying capacities. Malthus blamed the possible problems on god while Darwin observed that these things would occur naturally.

Malthus and Darwin shared similar beliefs of natural selection: by increasing the number of offspring, you increase the variations among offspring, and the strongest and most adaptable survive.

Malthus was an English goon that figured out carrying capacity was a natural, inevitable thing that reorganization or politics can't rectify. It was this that gave Darwin the early beginnings to his theories by helping explain factors of evolution fromm population.

Thomas Malthus was a political economist that observed that organisms can, in fact, produce a lot of offspring. This "overproduction" creates a hostile environment between the organisms, depleting the resources and therefore, decreasing the chances of survival. Charles Darwin took this logical idea and eventually arrived at the the theory of natural selection.

media type="youtube" key="4BbkQiQyaYc?fs=1" height="268" width="336" This is a video biology teachers have used for years. I would like you to watch it and then responds in the space below. Let’s just make a running commentary. Once you have had a chance to watch…it is a 7.3 minute video…the timing and pace is intentional so stick with it!

This was a long one, particularly through the Roman Empire and Golden Age of India. It was interesting to watch the Mongols invade China and the Black Plague decimate Europe. The last three hundred or so years are such an overload of new dots that we (as in the royal we) had to watch it twice to get where all the increases began, and the progression of their spreading.

It was interesting to see the rate at which the global population grew and where it grew. Everything was in India, China and Europe. It kinda makes me feel like the US is a giant fast food restaurant that was built last week and the older countries are the family owned restaurants that have been around since the town was founded. Oh well the whole video makes me scared we'll all starve to death tomorrow, so it doesn't matter. Stock your food! THE CARRYING CAPACITY APPROACHES!

Oh Blue, you make me laugh! :) I found the video to be very interesting for most of the video, the dots were so concentrated in Asia and Europe. It made me realize that the Americas are just so 'new', yet once the video's pace moved faster, the rapid increase of population in the world was scary (especially around the Industrial Revolution). Though, I have to say, when the Black Plague struck, I couldn't help but laugh at the disappearing dots... does that make me a bad person? Anyway, it's a reality check for everyone: if we continue living the way we do now, the Earth will be DEPLETED of resources. A global famine will ensue, and damnit, we're all gonna think back and regret the things we did (or didn't do). I'm gonna go ahead and start some kind of sustainable farm in my basement...

Terms...Terms...Terms Follow this link to find a clickable concept map of population terms. What I would like each of you to do is to pick any ten of the terms included in this concept and construct either your own meaningful concept map or write a paragraph of those ten terms.

The population size of APES is at seven right now. This population sets themselves apart from the other member of their species by electing to do more work (doesn’t seem like a smart thing to do from a natural selection point of view). They function in a very intense climate (7 am), deterring other organisms from joining and turning their s-shaped growth pattern into a j-shaped one. The regulating mechanism (the early time) eliminates the competition for resources by keeping other organisms out. Also, if there was no regulating mechanism, the population would grow exponentially as organisms told their friends to join. If the class continued without the mechanism, it would go into a boom and crash cycle, where organisms would readily join and then quickly lose interest. Them it would cycle back and the population would grow as it became popular again.

Once upon a time, there was a population of ogres. They ate lots of forest animals, and had to exert a lot of energy to keep up with the galloping gobblepods, their favorite delicacy. As the Gobblepods got faster, so did the ogres (convergent evolution, regulating mechanism), and for a long time, both of the populations maintained a steady growth. But due to a drought which caused the decimation of the pottyweed, their favorite plant, and the Gobblepods got hungrier, and they got hungrier, they also got slower. The ogres were then able to gobble the gobblepods up with ease, and their population shot into a j-shape. After a few years, the gobblepods population was almost eliminated, and the now bountiful ogres were struggling to find gobblepods to eat. Their population leveled out, and then dropped. To be contiunued.

Task ... Go out on to the web and find a population graph that tells a story. Your job is to post that graph and add a caption that you have created. The idea is to answer these two questions.... "What I see...." "What it means..."



What I see in this Saloniki Population Graph is that all three groups of people, represented by the different colors, grew and shrunk together between 1500 and 1900. The Greeks were consistently the most populous, and there were always fewer Jews than anything else. Around 1925, the green and orange populations (Turks and Jews) plummet. They disappear in Salonkini. The Greeks, on the other hand, dominate the Salonkini area. Their population shoots from around 125,000 in 1925 to nearly 300,000 in 1950. Based solely on the graph, I guessed that there was a war of some sort that caused the destruction of the Turkish and Jewish populations but led to remarkable proliferation among the Greeks.

Task ... Read p. 147 The article discusses a business decision made by International Paper. What do you think motivates businesses make these types of decisions?

I don't think this exists in some of the editions of our book, just sayin'.

Task ... Spend a few minutes searching the web for information linking a woman's educational level to either population growth or economic success of the family. Post your and a brief summary 2-3 sentences....do this first and the sources will be easier to find!

One website displayed data which indicated that Indian women's education levels and their infant mortality rate are inversely related. All of the websites seemed to agree that women are phsycially healthier and emotionally more balanced when they are educated. Anothe website suggested that sending more women to school in third world countries would lead to fewer children and indirectly improve standard of living. (Fewer children reduces poverty.)

Not really related to education, but China has a real problem concerning the female population. Due to 4 decades of the the one-child policy, and a cultural preference towards boys, women have been victim to forced abortions and infant females have been victim to infanticide- the gruesome homicide of infants due to their sex. This has resulted in a nearly 30 million more males than females in China. If you isolate China and do not let any marriage occur between Chinese citizens and non-Chinese citizens, you will have millions of males who will be unable to breed if they do not find a mate. If this is multiplied world-wide, will the age-old tradition/cultural desire of "falling in love" be replaced with male competitions of talent, ability to provide and affection, like they occur in the animal world? Also, would it totally restructure our genome?
