A recent post here about thawing permafrost releasing climate-warming carbon dioxide into the atmosphere was no exception. As CO2 has had no noticeable effect on climate in million years, until 20 years ago, when carbon tax was invented, any alleged climatic effects can be ignored. I ordinarily ignore comments like the one I quote above. Discover is a science magazine, not a platform for political grandstanding. And it is especially not a platform for ideas that run counter to basic physics and more than a century of hard scientific work by generations of researchers. This is not to say that I and the other writers and editors here at Discover view science as being infallible. Scientists know this better than anyone, so skepticism is one of their cardinal values. Journalists are also supposed to be skeptical and self-critical.

What about the fact that the “simple” organisms are buried in the lower levels and the more “complicated” ones are buried in the higher levels? Doesn’t this fact support the notion that simple organisms evolved into more and more complex organisms over time, with the more complex organisms buried and fossilized above the earlier and simpler life forms? Certainly this seems like a very logical assumption.

Views 2 Comments This cold spring brought a late season for the trees but this does not have any impact on what is going to happen in August and the fall for outdoor pollen and mold spores.
There are many weeds that cause seasonal allergies. Some of them include plantain, nettles, ragweed and others. We might even include some intense action like in the movies. The digestive system is a beautiful thing. Views 15 Comments I am going to do a follow up of my last post regarding the pollen season of and the cold spring that occurred.
First I would like to refer to this term that has been used this season called the pollen vortex.

Anthropology , Homo , and Timeline of human evolution The genus Homo evolved and diverged from other hominins in Africa, after the human clade split from the chimpanzee lineage of the hominids great apes branch of the primates. Modern humans, defined as the species Homo sapiens or specifically to the single extant subspecies Homo sapiens sapiens, proceeded to colonize all the continents and larger islands, arriving in Eurasia , —60, years ago,   Australia around 40, years ago, the Americas around 15, years ago, and remote islands such as Hawaii, Easter Island , Madagascar , and New Zealand between the years and The gibbons family Hylobatidae and orangutans genus Pongo were the first groups to split from the line leading to the humans, then gorillas genus Gorilla followed by the chimpanzees genus Pan.
The splitting date between human and chimpanzee lineages is placed around 4—8 million years ago during the late Miocene epoch. Each of these species has been argued to be a bipedal ancestor of later hominins, but all such claims are contested. It is also possible that any one of the three is an ancestor of another branch of African apes, or is an ancestor shared between hominins and other African Hominoidea apes. The question of the relation between these early fossil species and the hominin lineage is still to be resolved.
More recently, however, in , stone tools , perhaps predating Homo habilis, have been discovered in northwestern Kenya that have been dated to 3. During the next million years a process of encephalization began, and with the arrival of Homo erectus in the fossil record, cranial capacity had doubled. Homo erectus were the first of the hominina to leave Africa, and these species spread through Africa, Asia, and Europe between 1.

Top 10 Science Stories of Publication Date. January From the discovery of the Higgs Boson to an exciting new Mars mission, the Current Science and Technology team has been keeping up with innovative research and late-breaking scientific news all year.
These are external links and will open in a new window Close share panel Image copyright M Dodd Image caption Ancient life: These clumps of iron and filaments show similarities to modern microbes Scientists have discovered what they say could be fossils of some of the earliest living organisms on Earth. They are represented by tiny filaments, knobs and tubes in Canadian rocks dated to be up to 4.
That is a time not long after the planet’s formation and hundreds of millions of years before what is currently accepted as evidence for the most ancient life yet found on Earth. The researchers report their investigation in the journal Nature. As with all such claims about ancient life, the study is contentious. But the team believes it can answer any doubts.

Can science prove the age of the earth? No scientific method can prove the age of the earth and the universe, and that includes the ones we have listed here. Further, it has to be assumed that the clock was never disturbed. There is no independent natural clock against which those assumptions can be tested. For example, the amount of cratering on the moon, based on currently observed cratering rates, would suggest that the moon is quite old.
However, to draw this conclusion we have to assume that the rate of cratering has been the same in the past as it is now. And there are now good reasons for thinking that it might have been quite intense in the past, in which case the craters do not indicate an old age at all see below.
Conditions of Fossil Preservation: Rapid Burial, Hard Parts & the Elements
Introduction Evolution itself is simply the process of change over time. When applied to biology, evolution generally refers to changes in life forms over time. The Theory of Biological Evolution is most often associated with Charles Darwin, because it was Charles Darwin that proposed the mechanism of natural selection and accompanied that proposition with a large volume of empirical data providing evidence for biological evolution. Darwin was not, however, the first person to propose an evolutionary explanation for the diversity of life on earth.

One of the scientists who found the tissue and published a paper on it in the peer-reviewed literature 1 Mark Armitage was subsequently fired from his position at California State University Northridge. He has sued the university , claiming that he was fired because of his religious views. Instead, this update is about the fossil itself. Samples from the fossil were sent to Dr. I wanted the soft tissue that was found in the fossil to be dated, but it was not. According to a report in the journal Radiocarbon, bioapatite is actually preferable to soft tissue in many cases.
As the report states: Our investigation has shown that the pretreatment of bone with diluted acetic acid following a proscribed technique allows the separation of the bioapatite fraction from diagenetic carbonates. The report then gives a method by which original bioapatite can be extracted from a fossil. Does this conclusively show that the Triceratops horridus is not millions of years old?
However, I think it adds to the case that the bone is not millions of years old. When you also consider the fact that many other dinosaur bones and other things that are supposed to be millions of years old are dated as only being 22, , years old , you have to at least conclude that there is something wrong somewhere. Either the carbon dating system is not as robust as some want to believe, or the fossils are not as old as some want to believe.
It will be interesting to see what future research says about this.

Also, to introduce students to the major time periods in earth’s history, as well as to the role fossils play in helping us understand this history. Context This lesson is based on an online booklet that provides an introduction to the study of earth’s history, published by the USGS. Using careful analogies and written historical records, the authors help students understand the development of the geologic time scale, including how this depended on gathering evidence and making comparisons.
The major time periods in earth’s history are introduced, as well as are fossils and the role they play in helping us understand this history. Students will likely have been introduced to the geologic time scale in earlier grades, so this lesson is structured loosely to enable you to adapt the content to match the levels and needs of your particular students. Prerequisite knowledge for this lesson includes the idea that: Concepts covered in this lesson, including geologic history, age dating, plate tectonics, timelines, and fossils are prerequisite concepts for understanding the theory of evolution, which is another topic taught at this grade level.
One chapter called Fossil Succession, found in the online booklet Fossils, Rocks, and Time , is particularly useful in helping students understand that the basic idea of biological evolution is that the earth’s present-day species developed from earlier, distinctively different species. Benchmarks for Science Literacy, p. Specifically, it helps students understand that the kinds of animals and plants found as fossils change over time. It discusses how Darwin’s theory gave scientific meaning to the observed succession of once-living species in the record of earth’s history preserved in the rocks.
