The Evolution Lab contains two main parts: Students build phylogenetic trees themed around the evidence of evolution, including fossils, biogeography, and similarities in DNA. Students use both morphology and analysis of DNA sequences to identify relationships between species and to organize species and traits into phylogenetic trees. Along the way, students will watch seven videos that introduce the missions and give context for how the theme of each mission helps us understand how evolution has shaped life on Earth. Students explore an interactive tree of life and trace the shared ancestry of numerous species. Deep Tree helps students understand the scope of deep time and the points at which speciation occurred throughout evolutionary history on Earth. Students will complete the Evolution Lab with an understanding of how to build phylogenetic trees and the evidence for evolution. The Evolution Lab is best used as an introduction to an evolution unit. Students should possess prerequisite knowledge of the structure of DNA in order to complete several of the missions. The Evolution Lab is designed to be implemented in a teaching unit over the course of several class sessions.

It is divided into five distinct physiographic units: These regions each have distinct geology , climate , vegetation and human-use patterns. The lower Mekong basin rests on an ancient block of continental crust that has remained relatively stable since the Jurassic Period, a period of over million years. Large areas were covered by an inland sea during the upper Mesozoic Era, during which thick red-bed sandstones and evaporites were deposited.
All three enter the Mekong on the eastern bank.
The population of these fish has been steadily declining since the Khmer Rouge era, led by Pol Pot, and in , fisherman reported that on average only one giant catfish was caught per day.

In that year, the football coach, who had encountered the animal as a boy near the Chesapeake Bay , proposed it as a mascot to oppose the Wildcats, Tigers, and such of enemy teams.
Each is protected by an armor-like shell and also by its strong, beaked, toothless jaws. They are found throughout most of the temperate and tropical worlds. Turtles are the oldest living group of reptiles, dating back to the time of the earliest dinosaurs. But the safety of the shell is not guaranteed because many predators can overpower them. As a result, they must be quick to escape harm. In New Jersey researchers examined 53 living wood turtles that had been injured previously by predators.
About 27 of them were missing limbs, while 11 others were mutilated carapaces the upper shell of the turtle. However, turtles are sometimes said to live for years after being injured. Wood turtles are considered overland speed demons compared to the other species. Female turtles usually swim at a faster pace than that of their babies or the male turtle in order to protect their young from predators.
Soft-shell turtles Trionychidae are able to move their limbs at rates comparable to that in birds and mammals. They are powerful swimmers and run on land with startling speeds.
Jura 8 Comments This post took a little longer to get together than I expected. Much like the first installment of this series, I found myself writing more and more. If the filaments do prove to be genuine epidermal structures, then what does this mean for dinosaurs in general? When this little ornithischian was announced, many in the paleo community in particular the paleo-art community seem to have used this little guy as a license to draw feathers on pretty much any dinosaur.
After all, if protofeathers are found in ornithischians and saurischians, then it seems likely that they were a basal trait for dinosaurs in general. This is where we really need to start putting the brakes on.
In certain species, additional layers of membranous material are deposited around the embryo, but the calcareous calcium-containing shell does not form.
Z Click on an underlined word for more information on that subject. If the dinosaur or paleontology term you are looking for is not in the dictionary, please e-mail us. This meat-eater was about 20 feet 6 m long, weighing roughly 1. It is known from an incomplete skeleton from Mexico. The type species is L. These tar pits contain many animal bones, including Ice Age fossils.
Over species of Pleistocene Epoch plants and animals have been found and identified at La Brea dating from about 10, to 40, years ago , including many mammoths , mastodons , saber-toothed cats including Smilodon fatalis , dire wolves Canis dirus , giant sloths Glossotherium harlani , ground sloths, bison, a western horse, short-faced bear Arctodus simus , rodents, rabbits, birds, turtles, lizards, insects, mollusks, and many other animals and plants.
One ancient human skeleton was found in the La Brea pits about 17 bones from a woman who dates from about 9, years ago. Tar pits are pools of gooey asphalt that are created when crude oil seeps up from deep inside the Earth through a crack called a fissure. The less dense elements of the crude oil evaporate, leaving a deep, conical deposit of asphalt a very sticky mess.
Water pools on the tar, attracting thirsty animals. As animals get stuck in the tar, predators are attracted to the trapped animal, and then they get stuck in the asphalt too. The animals’ bones, teeth, and other hard parts are well-preserved in this environment but they turn brown from the asphalt.
Thursday 14 December Too much stress got the better of me. Heat of the moment thing and certainly not my intent to fan the flames. Froome is now facing a battle to save his own reputation and Team Sky have pulled together a team led by the high profile anti-doping lawyer Mike Morgan to present their defence to the Legal Anti-Doping Service, which will need convincing of the reasons Froome had double the permitted amount of the asthma drug Salbutamol in a urine sample submitted after stage 18 of the Vuelta on 7 September if he is to avoid a suspension and the rescinding of his Vuelta triumph.
The British rider has denied any wrongdoing.
This double and sometimes even tripled the amount of rice crops per year, strengthening the developing nation.
Recent Fossils Grand Canyon has so much more than pretty scenery. It contains an amazing diversity of rock formations with an abundance of fossils hidden within. The sedimentary rocks exposed throughout the canyon are rich with marine fossils such as crinoids, brachiopods, and sponges with several layers containing terrestrial fossils such as leaf and dragonfly wing impressions, and footprints of scorpions, centipedes, and reptiles. Ancient fossils preserved in the rock layers range from algal mats and microfossils from Precambrian Time 1, million to million years ago to a multitude of body and trace fossils from the Paleozoic Era million years ago.
What about dinosaur fossils? Not at Grand Canyon! The rocks of the canyon are older than the oldest known dinosaurs. If you find a fossil, please leave it for others to discover and scientists to study. You are welcome to take a picture or make a drawing of the fossil, then go to one of the visitor centers to see if a park ranger can help you identify it. Lacy bryozoan fossil found in the Redwall Limestone.
Fossils are the preserved remains of ancient life, such as bones, teeth, wood, and shells. Trace fossils represent the presence or behavior of ancient life, without body parts being present.
