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.
But, things just aren’t that easy. There are a number of potential problems with this interpretation of the fossil record. For example, it is interesting to note that some general kinds of fossilized creatures are very generally found in the same relative vertical orientation, with respect to each other in the fossil record, that they would have naturally been found in during life.

Along with their collection of insects to look at under microscopes we had our own collection of small fossils to view. This was a whole-school day and the organizers estimated about pupils attended the event. With teaching staff, helpers and organizers the estimate was about people on site during the day. Also inside the house were Timetaxi. We thank the Geological Society of London for providing a grant to pay for a wide-format pop-up projection screen which was used throughout the week to project images from our high-definition microscope.
An early morning start at Dinosaur Isle Museum saw the Landrover loaded up with a model dinosaur which had to be taken apart first and various small and very large and heavy fossils. This was taken by car-ferry to Hampshire. Stopping off first at the University of Portsmouth to collect some more large fossils we then drove on to the installation in the Cathedral.
The first job was to get as near as possible to the building in order to off-load the vehicle. Having identified a suitable location near the arches of the ambulatory we began constructing the dinosaur, then adding the fossils and their interpretation. The picture above shows part of the installation. Thanks go to Dr David Loydell of the University of Portsmouth for the loan of additional fossils, and to the vergers team for help with setting up the display.
Engaging in argument from evidence The Need For This Lesson Students have explored how fossils are formed, where fossils are found and the work of paleontologists, but fossils are more than just fun to look at in class. Fossils provide us with clues about the prehistoric past if we know what to look for, and how to read them, when we examine them. In this lesson students find out what stories of the past can be found using fossils as evidence. This is a powerful lesson for middle school students.
They are examining fossils beyond the concrete identification to a more abstract analysis of the stories found within.
fossil – remains of an organism; phylogenetic tree – evoluationary history; 6. Examine the fossil that was unearthered in a museum, apparently the labels and other information were lost. Using your fossil record, determine the time period this fossil is likely from. Montanian or californian. 7.
Kuban last revised Jan. I use this format to avoid webbot spamming Fig. Brown’s website and book showing what he calls the “Rupture Phase of the Flood” Introduction Walter Brown, a young-earth creationist and retired mechanical engineer, has developed a “Flood model”1 which he believes accounts for virtually all geologic evidence on earth, as well as a variety of astronomical phenomena. His central thesis is that only a few thousand years ago the Earth’s entire crust consisted of a granite slab 20 to 60 miles thick until recently, claimed to be 10 mi thick , suspended over a large reservoir of highly pressurized water.
According to Brown, due to centuries of “tidal pumping” from the Moon’s gravity, the crust suddenly cracked and burst open, violently releasing the subterranean water and flooding the entire earth Fig. He argues that large masses of rock and water were ejected into outer space during this massive eruption, creating all the asteroids, comets, and meteoroids in our solar system.
He further claims that the immense slabs of broken crust, which he calls “hydroplates,” undulated, heaved and slid thousands of miles in a matter of months or less, and then crashed into each other to form mountains within hours. Brown presented early versions of the model during the ‘s Brown, , and subsequently revised and expanded it into a more comprehensive model of earth history, which he described in a book entitled In the Beginning: Compelling Evidence for Creation and the Flood, now in its 8th edition Brown, He provides updates and excerpts of large portions of his book at his Creationscience.
Brown indicates that he is “Director of the Center for Scientific Creation” in Arizona, which apparently consists of two people he and his wife. Brown’s Flood model and associated claims are overwhelmingly rejected by conventional scientists, since they strongly conflict with many lines of evidence that the Earth and solar system have had a long and complex history, and that the Earth is about 4.

Yet the months since then show no global warming at all. Marc Morano – Climate Depot November 4, 2: Yet the months since then show no global warming at all Fig. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset shows no global warming for 18 years 9 months since February , though one-third of all anthropogenic forcings have occurred during the period of the Pause.
The accidental delegate from Burma provoked shrieks of fury from the congregation during the final benediction in Doha three years ago, when he said the Pause had endured for 16 years. Now, almost three years later, the Pause is almost three years longer. It is worth understanding just how surprised the modelers ought to be by the persistence of the Pause. NOAA, in a very rare fit of honesty, admitted in its State of the Climate report that 15 years or more without global warming would demonstrate a discrepancy between prediction and observation.
The steepness of this predicted response can be seen in Fig. But, despite the very substantial forcings in the 18 years 9 months since February , not a flicker of warming has resulted.
A stochastic DNA walker that traverses a microparticle surface. Nat Nanotechnol, 11 2 , pp. These engineered machines typically move along precisely defined one- and two-dimensional tracks. DNA hybridization reactions, the nanoscale movements of the walker can lead to the generation of a single-stranded product and the subsequent immobilization of fluorescent labels on the microparticle surface.

Before the scientific era, people often made up imaginative stories to explain what they saw in the world. The scientific method changed that by requiring rigorous experimentation to test hypotheses and determine what is real. With the Theory of Evolution, people are back to making up imaginative stories. The primary advantage of complete metamorphosis is eliminating competition between the young and old.
Larval insects and adult insects occupy very different ecological niches. Whereas caterpillars are busy gorging themselves on leaves, completely disinterested in reproduction, butterflies are flitting from flower to flower in search of nectar and mates.
Examining the Fossil Record
My cat used to drink from the garden pond and never seemed to suffer any ill effects, and you often see dogs drinking from muddy puddles. So why do humans have to be so careful and only drink clean water? Will it form sediment that gets buried beneath the seabed and eventually turns into plastic “oil” or “coal”? I had previously suspected that some tadpoles are late undergoing metamorphosis, but this one really missed the boat. Is this a recognised phenomenon, and what is the explanation?
Is there an accepted ratio or does it vary, and if so by how much?

A Twa hunter-gatherer in Uganda climbing a tree to gather honey. Nathaniel Dominy Early Human Ancestors May Have Walked AND Climbed for a Living Africa 31 December The results of recently conducted field studies on modern human groups in the Philippines and Africa are suggesting that humans, among the primates, are not so unique to walking upright as previously thought. The findings have implications for some of our earliest possible ancestors, including the 3.
Associate professor of anthropology Nathaniel Dominy of Dartmouth College, along with colleagues Vivek Venkataraman and Thomas Kraft, compared African Twa hunter-gatherers to agriculturalists living nearby, the Bakiga, in Uganda. In the Philippines, they compared the Agta hunter-gatherers to the Manobo agriculturalists. They found that the Twa and the Agta hunter-gatherers regularly climbed trees to gather honey, an important element in their diets.
More specifically, they observed that the climbers “walked” up small trees by applying the soles of their feet directly to the trunk and progressing upward, with arms and legs advancing alternately. To do this successfully, they said, required extreme dorsiflexion, or bending the foot upward toward the shin to a degree not normally possible among most modern humans. They tested their hypothesis by conducting ultrasound imaging of the fibers of the large calf muscles of individuals in all four groups.
The results showed that the Agta and Twa tree-climbers had significantly longer muscle fibers than those of their agricultural counterparts and other “industrialized” modern humans. It demonstrated that a foot and ankle bone structure adapted primarily for walking upright on land does not necessarily exclude climbing as a behaviorally habitual means of mobility for survival.
The implications for our possible early human ancestors, such as the species Australopithecus afarensis, are significant.
Earth Science with Lab
The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.
We are told that these methods are accurate to a few percent, and that there are many different methods.
