Stone Tool 1.83M Years Old Discovered In Malaysia

goran72 writes with news out of Malaysia that archaeologists have announced the discovery of stone tools more than 1.8 million years old — the earliest evidence of human ancestors in South-east Asia. Researchers believe the tools were made by members of the early human ancestor species Homo erectus. The tools actually date as slightly older than the earliest H. erectus fossils, which came from Georgia and China. No bones of that antiquity have so far been found in Malaysia. "The stone hand-axes were discovered last year in the historical site of Lenggong in northern Perak state, embedded in a type of rock formed by meteorites which was sent to a Japanese lab to be dated."

    Since the earth is only 6000 years old, the simplest explanation (Occams razor) must be these stone axes must have been created by some stone-age aliens in their big granite spaceships.

      You were probably not a Boy Scout as a kid. There is actually a lot of work to make a sharp object out of a stone that is sharp and concisely sharp enough to be useful. Weather erosion like to make smooth surfaces not sharp ones. Rock chips at best will be good for poking but not cutting. So man made stone tools are actually quite different then a naturally occurring tool

      The article doesn't say, but if it's a flint then the stone is incredibly brittle and takes a considerable amount of skill to work without shattering the stone. Working flint (or any stone) to a point or an edge leaves a distinctive pattern of markings on the stone which would be all but impossible to have occurred naturally as you basically need to flake off the unwanted bits of flint until you get the desired edge or point. Natural weathering of stone tends to fall into a limited number of types, predominantly rounding through contact erosion, and shearing which is usually caused by freezing water breaking a stone in two. Neither of the natural patterns are likely to lead to the organised pattern of chips that a worked stone would exhibit.

      It depends. Up to this day there is a big number of inconclusive cases where archaeologists "discovered" sets of "older stone tools" but there is no clear consensus but acid disputes.

      Of course when you have the nice bifacial spearpoints depicted in most books your argument is valid, but in a lot of "unifacial industries" typically oriented to cutting wood and plants, there are no such clear traces of chipping you allude. In several areas, a lot of originally "non interesting" stones are being reevaluated (always with several levels of controversy); the case is that probably most of the "stone age" tools and cultures are of this "ugly" kind.

      Work with the native American cultures in Utah has shown that flint was not "chipped" into shape by striking. Arrow heads and spear points were shaped by heating the rock and dripping water on it. Thermal shock did the hard work. Yes, it took a considerable amount of work and skill to shape, but does not require impact that might shatter the rock. Pretty sophisticated technology for the day, but really all you needed was rock (flint, jasper or similar), fire, water and a steady hand. Try it yourself.

    I have no problem with the imterpretation that these are stone tools from 1.8 MYA (and you can tell by my pretentious use of the "MYA" abbreviation that I was once on the road to related Ph.D.).

    But I don't understand this:

    The stone hand-axes were discovered last year...embedded in a type of rock formed by meteorites....

    How or why were these tools embedded in rock formed by meteorites? This rock was either formed before or after the tools. If formed before, they could only have been embedded manually, by H. erectus miners, I guess.

    If the rock formed later, then these tools survived intact a meteorite strike, which seems unlikely. (Or was the rock formed by meteorite splash sediments?)

    There is one other possibility, but it's so unlikely that I reject it: that the tools and rocks were thrown up in to the air and the whole mess coalesced and solidified.

    I wish the article had more info, or I could find the original paper, although here is an AP article with a photo of the rocks.

      Possibly, but we're talking almost a million years older than the oldest known organized religion for which any evidence exists. We're talking so early that many anthropologists reject outright that such people had the mental capacity for complex ritual.

      (I suspect the anthropologists are wrong on that, but the lack of any evidence of ritual worship older than about 800,000 years ago takes precedence over my personal feelings on the matter.)

    I don't think the comparison to Intelligent Design is very useful. In Intelligent Design, we know nothing about the Designer, the Designer's methods or the Designer's goals. There is no real experimental work being done.

    In contrast, we have a pretty good idea of who made (or who would have made) these tools, what their goals were and what their methods were. Based on this, we can do quite a bit of experimentation to figure out what we don't know (or even whether or not they're tools at all).

    Carbon dating is not the only dating technique. There are actually perhaps 30-35 different common dating techniques with useful time range from a matter of decades to billions of years, tens of billions of years infact.

    Another common one is radiometric dating which gives you a range of 700 million to 50 billion years (!). In a way Carbon 14 dating is radiometric dating, it's just using one particular isotope. In reality there a many different isotopes that may be used to suit the range you need.

    Since the stone tool is not organic matter, carbon 14 would not be useful. Carbon dating gets too inaccurate after 50,000 years.
