Relationships of Platyhelminthes excluding Acoelomorpha to each other    The oldest confidently identified parasitic flatworm fossils are cestode eggs found in a Permian shark coprolite , but helminth hooks still attached to Devonian acanthodians and placoderms might also represent parasitic flatworms with simple life cycles. This makes it difficult to work out both their relationships with other groups of animals and the relationships between different groups that are described as members of the Platyhelminthes. Since then molecular phylogenetics , which aims to work out evolutionary “family trees” by comparing different organisms’ biochemicals such as DNA , RNA and proteins , has radically changed scientists’ view of evolutionary relationships between animals. Platyzoa are generally agreed to be at least closely related to the Lophotrochozoa , a super phylum that includes molluscs and annelid worms. The majority view is that Platyzoa are part of Lophotrochozoa, but a significant minority of researchers regard Platyzoa as a sister group of Lophotrochozoa. The next evolutionary step was a dietary change from epithelium to blood.

Recently the subject of guys and breakups came up and Sabrina and I went back and forth about what guys generally go through when they breakup. Simple enough to say, but I know plenty of women will talk about how some guy came off like an insensitive jackass after the relationship fell apart because of his actions post-breakup. If a guy is profoundly obnoxious or terrible after a breakup, it is most often a testament to how rough the breakup was on him.
Some people cope by lashing out. Jerry Seinfeld once said that breaking up a relationship needs to be like taking off a Band-aid — One motion: In the same regard, when a relationship ends, it is much much harder for a guy to go back and discuss and revisit and talk through and explain, etc. Personally, I have had breakups where I pretty much went cold.
You can still read it here: Where to meet Indonesian girls?

We have really hit it off. Being in a rush, I decided to go in my wheelchair, without the leg braces I usually wear. I am a paraplegic, paralyzed from just above my waist down to my feet. I have been a paraplegic since I was a little girl. My legs are very thin and flaccid, but I still think of myself as attractive, even sexy. My ample breasts are my best feature so I like to show them off a little with a tight blouse.

Let me make this simple for you… Guys want to capture a prize. And yeah, of course, guys want sex, so if you think that sex is the only bargaining chip you have then you will always feel paranoid about men using you. Think about it — do you honestly think that men choose a woman for their one exclusive relationship just for sex?

Natalya Shyshlina An international team of scientists, including a professor of the Faculty of Soil Science, MSU, has studied burial sites dated back to the Bronze Age at the border between Kalmykia and Stavropol Territory and found traces of domestic barley on the walls of vessels. Local residents did not practice agriculture at that time, so the barley was likely received from people of farming cultures in exchange for other goods.
The details of the study were published in Vegetation History and Archaeobotany. We analyzed the phytolith composition and pollen of wild steppe plants and domesticated crops namely, barley. Direct carbon dating of one of the samples showed that the spikes and stems of barley were used by local steppe communities during burial ceremonies,” explained Anatoly Bobrov, a co-author of the work and Professor of the Faculty of Soil Science, MSU.
The scientists explored barrows and catacombs, underground burial constructions, along the East Manych River that flows through the territories of Stavropol Territory and Kalmykia. In the middle of III century BC when the burials took place, this region was occupied by cattle breeding nomads that moved between the foothill of Caucasus and Volga and Don Valleys. The scientists found charred remains of wild plants such as amaranth or gromwell on the floors of barrows, and in the walls of ware and ritual vessels.
Local peoples began to cultivate plants not earlier than at the end of the Bronze Age. The authors of the work studied the remains of plants on the walls of clay vessels in the burial sites of the catacomb culture. Such remains are accumulated over time, and the layer may be several millimeters thick. In these layers, the scientists found fish and animal bones and seeds of plants, as well as small particles consisting of pollen, insects and collagen threads.
Archeological Sites and Museums in Italy
HOME Archeological Sites and Museums in Italy This page describes the most conspicuous part of Italy’s archaeological heritage, as well as some basic information for an immediate reference, and a choice of itineraries and suggested stops divided by regions. An outline of art and culture that testifies the extraordinary richness of history and beauty that has made Italy the ultimate attraction for travelers, artists and students of all times and from all countries.
Prehistoric civilization There has been human settlement in Italy since Paleolithic times, as is demonstrated by numerous discoveries: Prehistoric art is fairly widespread although it varies considerably in importance, type and age. Among the most ancient objects is the so called Venus of Savignano, dating back to the late Paleolithic period, which was found near Modena and is now held in Rome at the Museo Pigorini.
The Cradle of Humankind is a paleoanthropological site about 50 km (31 mi) northwest of Johannesburg, South Africa, in the Gauteng province. Declared a World Heritage site by UNESCO in , the site currently occupies 47, hectares ( sq mi) and contains a complex of limestone caves. The registered name of the site in the list of World Heritage sites is Fossil Hominid Sites of South Africa.
Life timeline and Nature timeline Cueva de las Monedas Nearly caves have now been discovered in France and Spain that contain art from prehistoric times. Initially, the age of the paintings had been a contentious issue, since methods like radiocarbon dating can produce misleading results if contaminated by samples of older or newer material,  and caves and rocky overhangs where parietal art is found are typically littered with debris from many time periods.
But subsequent technology has made it possible to date the paintings by sampling the pigment itself and the torch marks on the walls. For instance, the reindeer depicted in the Spanish cave of Cueva de las Monedas places the drawings in the last Ice Age. The oldest date given to an animal cave painting is now a pig that has a minimum age of 35, years old at Timpuseng cave in Sulawesi, an Indonesian island. Indonesian and Australian scientists have dated other non-figurative paintings on the walls to be approximately 40, years old.
The method they used to confirm this was dating the age of the stalactites that formed over the top of the paintings. Cave paintings in El Castillo cave were found to date back to at least 37, years old by researchers at Bristol University, making them the oldest known cave art in Europe, 5—10, years older than previous examples from France.

I had an older brother and sister 12 and 15 years my senior respectively, parents who were happy together, and my aunt and cousins lived one street over. I had a lot of attention growing up being the baby and all, but my main source of affection came from my Dad. To define our relationship like that would misconstrue it; we were simpatico.

Realize stressing gets you nowhere First, you need to realize that getting all wound up over the state of your relationship serves no purpose, ever. It causes problems within the relationship, and more importantly, it takes a huge toll on your sense of self and self-esteem. When you care too much, you inevitably become attached to a certain outcome. You invest mental energy in making sure things go a certain way.
I have been guilty of stressing over past relationships. It was always the same pattern. From then on, the relationship was no longer enjoyable. Every interaction and conversation became a test to see exactly where he stood and how he felt. The problem is our minds trick us into believing there is some sort of payoff to this type of thinking.
Like it will somehow lead us to a place of confidence and clarity. It will lead you in the opposite direction, rather, and cause you to feel even more uncertain and insecure. It is not there to serve you and give you things like happiness and self-esteem.
