The prehistoric humans who lived in the east of the African continent more than 320,000 years ago would have used more sophisticated stone and obsidian instruments than was previously considered, indicate the results of an international investigation published in the scientific journal. According to the publication, half a million years ago, our ancestors had to face a period of extreme environmental instability.

It was considered that they dated from only 60,000 years, but the isotopic courting The mystery increases with the fact that no fossil remains of humans have been found, so it is not known exactly which species were their owners.

It is best to approach and Buy Assignment in order to get the best work. The skills developed by Neanderthals continue to be the subject of debate among paleontologists. As new remains are unearthed, as has now happened in France, they get more information about the capabilities of this species.

Did they develop these behaviors before encountering the sapiens or was it the result of having come into contact with them?

Technology of prehistory

During the Stone Age, the human being used raw materials from his environment to help him with daily tasks. The main materials were, stone and wood. The stone, specifically list is the most common material that can be found in a prehistoric site. Not that it was the most used material – which would probably be the Assignment Help Online case but it is the one that has lasted best and has stood the test of time.

The most probable thing is that the human being of Prehistory used all the materials of his environment, although the one that most reached us is undoubtedly the stone. Surely the stone was one of the first tools used by humanity.

It is a resource of great abundance, forceful, durable and multifunctional. It would be something like the prehistoric version of a multipurpose Swiss army knife. The stone is the technology of Prehistory for the great abundance and diversity with which it is found in the archaeological record

The silex: the material in Prehistory

Of great rigidity but at the same time, easy to work made it the perfect tool stone of considerable dimension was composed to obtain flakes, sheets or sharp pieces of the mother stone. The flint has a superficial layer called cortex, of a generally clear color.

Size by pressure: an element was used to press the core of the stone from which the flake was extracted. This type of technique was much more elaborate and allowed to obtain a sharper flake with certain characteristics and adapted to its purpose.

How to identify a worked peg

The blow on the flint causes waves on the nucleus (the beating waves) that indicate the direction from which the piece has been hit. This part, the exact area where the beating has been received, is called a bulb and there is a protuberance from where the waves expand.

The flakes are the pieces or fragments extracted from the core of the stone by striking and whose physical characteristic is that its length is less than twice its width. That is, to give you an idea, a flat sheet.


We have the plates. Unlike the flakes, the blades have a length twice their width and in their dorsal part have the sides. When the flakes and sheets are worked, what is called the retouching is elaborated, the edge of the piece to make it more useful, whether to crack, scrape or nail.

Samsung Galaxy S9 & S8 Android Supported Device | A Comparison



Samsung Galaxy S9 & S8

Picking up an Android smartphone that could support all the Android Apps is a critical choice. The Android world is saturated and founding the best Android smartphone is harder when the choices vary along with the capacities and performance. You would find from super-costly leader smartphones to reasonable models that make a couple of computed bargains.

Some of the models explicitly intended for, say, fantastic photography with a great camera, and supporting apps and some would only be able to support apps but the image results are annoying.

So, it is on you what you want for yourself to have a great smartphone experience. If you want to explore more, please visit technpick for a detailed guide on top quality smartphones existed on the market today.

Android Supported Device | A Comparison Of Smartphones

This comparison would make clear the stats and worth of both the Android supported devices. It will reveal the inside of the phone in depth and would give you a clear picture. And in fact, OS versions are also on grow. So, it is important to know more about how to determine the compatibility with different Android apps and OS versions.

It is a fact that whatever phone you get; you would keep it for a maximum of two years. It compelled me to pick the top rated and best smartphones that support Android and also could give you best performance. During the picking process, I tried my level best to choose from varieties of phones specifically targeting the specification and classifications.

Samsung Galaxy S9 & S8

Let us explore our first selection of the smartphone with is a fully Android support piece of beauty. Samsung Galaxy S9 is the smartphone which is the latest one in the S series by Samsung. As compared to Samsung Galaxy S8 there is no wonder in the craft, as the outline reused on it.

Especially when we talk about the S8 the interface and the design are quite upgraded as compared to S7 edge. S8 Plus and S9 have close resemblance on the look. And the recent upgrades in the Android system making both the same.

But the S9 has a bit different in look due to its bezel-less body and long height face. Due to the new model, it is a bit expensive than the Samsung Galaxy S8 Android Smartphone. You would only get three or more upgrades on this new release by Samsung.

Performance And Features

If you notice the Samsung S8 it is coming with the single mark sensor on the back of the phone. The sensor is placed with the camera and your fingerprint can be taken through this sensor. I am personally against the placement of the sensor at the back of the phone. Thanks to the company for making the placement correct in the making of the Samsung Galaxy S9.

The company realized the mistake on S8 they already committed and they removed it by the placement of the sensor beneath the phone camera at the rear, not like the traditional way was.

Camera And Battery Life

Before discussing the camera of these Android supported smartphones I would like to share the battery life information as without battery a phone is just a dumb box of nothing. Both the phones have the same battery life and capacity. That means no attention paid to this part.

Both the Android supported smartphones are capable of being alive for 14 hours and 13 minutes. With a smartphone where you operate heavy data loading and uploading and many online hard apps active all the time, it is a pretty good backup time for Android devices.

Let us explore the camera of Galaxy S9, you would get surprised to hear that it is coming with the same 12MP camera which was experience on S8. There are some progressive and essential improvement the company made in the framework as I already mentioned that the company placed the fingerprint scanner beneath the camera.

It is also not sounding good that it is coming in a single camera. As the S9+ is coming with dual cameras that have the ability to switch between f/1.5 and f/2.4.  There’s likewise a Super Slo-mo setting that records up to 960fps with movement recognition so that you won’t miss a trap.

With the missing of the second camera, you are also missing the legitimate captures of the shots as the S9+ can provide you.  However, Samsung’s specific center completes a first job of copying the impact.


Overall if you compare the S9 and S8 you would see that S9 is an overhaul version of the S8, I am assuming that the price of this phone increased due to the change in the model and some decrease on the bezel and fingerprint sensor placement beneath the rear camera.

Without the improvement, I explored I could not explore anything else. The battery life improves for an hour and also some of the new built-in apps are making a bit different.

If you are using a Samsung Galaxy S7 edge and want to upgrade in the same row then I would suggest S9 for you. But if are already on S8 and want to have a new one than the S9+ would be a better choice than S9.
