Our two days: Our History studies breakthrough and a neat article we found disproving modern man came from neanderthal.
And late last night I was looking at the history encyclopedia bought and had already started to use and found lots of lessons and activities to suppliment and blend together like those videos from scientific frontiers on PBS I posted before. I had an epiphany and of how to teach this whoe era best. I’ll get into it later when I feel better. Here’s another link we used to visualize prehistory and archeaology.

Neanderthals Didn’t Mate With Modern Humans, Study Says
A Small Population
Contrasted with modern humans, Neanderthals exhibited a greater number of letter substitutions due to mutations in their mitochondrial DNA, although they seem to have undergone fewer evolutionary changes overall.
The fact that so many mutations—some of which may have been harmful—persisted in the Neanderthal genome could indicate the species suffered from a limited gene pool. This might be because the Neanderthal population was smaller than that of Homo sapiens living in Europe at the time.
A small population size can “diminish the power of natural selection to remove slightly deleterious evolutionary changes,” Green said.
The researchers estimate the Neanderthal population living in Europe 38,000 years ago never reached more than 10,000 at any one time.
This could have been a factor in their demise, Green said.
Homo neanderthalis first appeared in Europe about 300,000 years ago but mysteriously vanished about 35,000 years ago, shortly after the arrival of modern humans—Homo sapiens—in Europe.
“If there were only a few, small bands of Neanderthals, barely hanging on, then any change to their way of life could have been enough to drive them to extinction,” Green said.
“One obvious change would have been the introduction of another large hominid—modern humans.”
Stephen Schuster, a molecular biologist at Pennsylvania State University, said the new study should silence a lot of theories about interbreeding between Neanderthals and modern humans.
The study shows that “at least for the maternal lineage, there are no traceable genetic markers that suggest admixture of Neanderthals and modern humans,” he said.
Schuster added that the researchers were exceptionally careful to isolate the Neanderthal DNA.
“Many more precautions were taken to ensure that no contamination with human DNA has flawed the analysis,” he said, noting that researchers sequenced each letter about 35 times to be sure of their work.
“This was the weak point of previous reports,” said Schuster, who was not involved with the study.
Thomas Gilbert, an ancient DNA expert at the University of Copenhagen in Denmark who also was not involved in the study, called the research a “step forward” and a taste of what might come when the Neanderthal nuclear DNA is finished.
The team’s argument that the Neanderthal population was small 38,000 years ago is speculative, Green said, but “it’s better than what we could have said before.”
Ayat from Quran coming soon, God willing.

Timeline of the prophets perfect for what we are plannng for History. More detail on my recent lesson planning. Yesterday, I had Sakina copy the What is History? introduction in our book. It was two paragraphs. Then we filled it in her binder under Social Studies, not in “copying” under the writing section. I reorganized her binder last night, filed more schoolwork that had been completed, added new assignments and added the reading section. I needed that for the “memory work” subsection where we would keep the last three poems she has written down and memorized from or substituted from lessons in First Language Lessons, by Jessie Wise the same co-author of The Well Trained Mind. Last night, I outlined this school year and History. I made more folders in my computer, divided our study of History into segments from an earlier date to a later. I came up with a total of seven but we’ll see how it plays out because a lot of the first and last prophets or notable people of war, advancement, religious or social change overlap with other important people or civilizations. I am definately going to start a timeline on the wall soon. For this purpose I had gotten “deli paper” a seven foot long, huge wide roll of paper from the “teacher store” but eventually it got crumpled, cut, torn and then obliterated when we moved across town! So far we have covered Creation, Adam, Cain and Abel from the Quran and then the first humans, making tools, archaeology and artifacts. http://prophetsofallah.tripod.com/prophets/id4.html In addition to having her write a short beginning of the introduction to World History, she copied the term artifact and wrote a definition. We labeled the top “Pre History Terms and definitions” or something like that. I also wrote “excavate” and archaeology but let her take a break and write the definitions tomorrow. It will be filed under History. Even though in the History book we are following, I already checked out the book recommended in WTM which is meant for primary school use (1-5) and the first page had a diagram and explanation on digging. (As in excavation) Our book doesnt have that so that’s why we looked at videos online yesterday of exciting new discoveries being made recently all over the world in archaeology and spent time learning about how we know about the past. We have a lot of flint around here and she loves finding rocks and “crystals” and have been for a walk at the nearby stream and park so I plan on taking them again soon, inshaAllah so we can bring some rocks home and experience hands-on shaping and of course, the sparks! The funny thing is, nature walks behind our old wooded area apartment was very common and we always took interesting rocks or those I though were fossils. We actually moved them when we moved, too. I have always loved Earth Science and had a passion for different rocks and semi-prescious stones. Just the other day I told Sakina got very excited when I told her I would take her to this hall in a building where they have hundreds of rocks lining up the walls and on display. She asked me where it was and I said here in the city, not far, explaining the amazing rocks and fossils were in a building at a big, famous university. I reminded her about before when I was teaching _____’s boys and that’s when I saw this neat, free place, when I went with my homeschooling group on a “class” for the kids. I told her all about it: the professor gave tested our knowledge, gave a speech, then the children asked questions and after we were allowed to bring rocks for the teacher to identify and view all the different minerals, crystlals, and all the different rocks in the hallway. When we used to take nature walks and collect rocks I used to tell her I was keeping some of them not because they were pretty, but I thought they belonged to something like an animal or other living thing or that it meant something like I found a tool or something. I could keep it and take her to that place I went and have the professor tell me what kind of rock it was, where it came from and if it was a fossil or some kind of artifact. I know she doesn;t remember that it was almost two years ago, so when I told her recently of taking her to the rock hall and her excitment and wonder over the idea I asked her didnt she remember and she told me no, with surety. I knew she never rembered me telling her about it. Anyway, I hope to take her soon and lug or box of rocks and gather some of the ones we even use around the house for decoration. If we have a true fossil or artifact that will really make learning about archaeology fun and interesting. She wasn’t really that inspired about the first humans lesson, tools and cave art until she saw videos online and saw perfectly preserved, fully clothed bodies dug up, studied and displayed that were over 1,000 to 3,000 years old. Collecting more rocks and flint, taking another walk and going to that science hall will really bring it together for her; make it fun and memorable. inshaAllah.
Sakina did some other school things but I will post that later. Here is the History plan I wrote last night:
This years Plan of study for History
- Using our History Book, make a timeline. Start with BC, segments of time and dates with appropraitte spaces. (BC is much longer) Fill in start and finish dates for eras, civilizations and dynasties we are covering. Use pencil until all areas around each finshed studying. Then fill in, using colors to visualize the timespan and understand the overlapping times; i.e. what’s going on in different parts of the world at the same time. (note2 self go on disk and groups and find those 2 printable timelines I liked)
- In each segment/ page of our book, World History Encyclopedia read to Sakina and have her dictate back to me, or reread if she chooses to, write a summary of her own, illustrate the subject, then file in her binder. We will do this for each page/segment covered in the History book we are following. When finished, Sakina reads supplemetary books we already own. (yes I actually have most from dinosaurs to prehistory to creation and Iblis, to Abraham, then many story books on Roman and Greek mythology all even up till African Americans and the civil rights movement. I bought books from every major theme in history and folklore of all periods and cultures. So she can read them, but in ORDER along with History we are studying. I have many other supplimental ideas for each history segment, but I will list tthem once we go through it and prepare it by planning at another time. Also there are additional “enrichment” ideas I have and MANY recources available to me, audio visual, etc available to Sakina is she is particulary interested in something we are covering. ( I either alread has a lot of these book having collected them over time or from the last fewe years of homeschooling groups and teaching my friend;s kids and homeschooling them as well as bookstores, used bookstores, thrift stores, and the library bookstore where all childrens hardcover storybooks and non fiction are 50 cents al hamdulilah. So yes, I actually have everything she needs. If there is a movie not too vulgar of that period we are studying I will watch that with her too.inshaAllah
- Upload asmuch as I can to my blog, pictures, activities, also documents scanned that either she or I did. Photograph all projects so they dont pile up, then throw them away within a couple weeks, depending on my child’s pride of it or attatchment! Document and photograph main school binder, books and schoolwork. Ok well I don;t have to photograph her schoolwork! I keep everything anyway. I rarely throw anything out.
- Continue ORGANIZING and throw some stuff out! Need to make more shelving or hanging bins for school stuff, materials, kid bins, and teacher planning.
ok, thats it for now, whew! been bloggin half the day and night! P.S. I have to reset the time somehow on this page it’s complelty off. It says its 4:33 pm and its really 11:34 am. Maybe that’s a good thing, it’s off. Other ppl wont know I usually blog between 10 pm and 7 in the morning!
