Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.
Top 10 Signs Of Evolution In Modern Man Humans Through history, as natural selection played its part in the development of modern man, many of the useful functions and parts of the human body become unnecessary. What is most fascinating is that many of these parts of the body still remain in some form so we can see the progress of evolution. This list covers the ten most significant evolutionary changes that have taken place – leaving signs behind them. Goose Bumps Cutis Anserina Humans get goose bumps when they are cold, frightened, angry, or in awe. Jacobson’s Organ Vomeronasal organ Jacobson’s organ is a fascinating part of animal anatomy and it tells us a lot about our own sexual history. Junk DNA L-gulonolactone oxidase While many of the hangovers from our “devolved” past are visible or physical, this is not true for all. Extra Ear Muscles Auriculares muscles Early humans ate a lot of plants – and they needed to eat them quickly enough that they could eat a sufficient amount in one day to get all of the nutrients they needed.

Understanding Evolution The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces. While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow.

Tree of Life Web Project Evolution Resources from the National Academies In the News: Your Inner Fish – A Scientific Adventure Have you ever wondered why people look the way they do? Why our hands and feet have five digits instead of six? Follow that adventure now on PBS Darwin's Insights Continue to Inspire the Academy's Work The ideas of Charles Darwin and the concept of evolution by natural selection continue to have a profound influence on modern biology – they permeate almost every area of scientific exploration. In 2009 the National Academy of Sciences joined many other organizations in the international scientific community to celebrate the 'Year of Science,' which commemorated Darwin’s 200th birthday and the 150th anniversary of the publication of his masterwork On the Origin of Species. In 2010, the National Academy of Sciences awarded its most prestigious award, the Public Welfare Medal, to Dr.
Erbe medicinali Instant Anatomy Welcome to Instant Anatomy Capsula interna Die Capsula interna (deutsch: innere Kapsel) ist die größte Ansammlung von Nervenfasern, die zur Großhirnrinde aufsteigen oder von der Großhirnrinde absteigen. Anatomie[Bearbeiten] Horizontalschnitt durch das Vorderhirn, Basalganglien blau Anatomisch wird die Capsula interna innen von Thalamus und Nucleus caudatus, außen von Globus pallidus und Putamen begrenzt. Im Horizontalschnitt sind ein Crus anterius (vorderer Schenkel), ein Crus posterius (hinterer Schenkel) und das die beiden Schenkel verbindende Genu capsulae internae (Knie) zu erkennen. Folgende wichtige Bahnen ziehen durch die Capsula interna und verbinden so die Großhirnrinde mit tiefer liegenden Strukturen beziehungsweise dem Rückenmark: Im Crus anterius verlaufen: Tractus frontopontinusvorderer Thalamusstiel Im Genu verläuft: Tractus corticonuclearis Im Crus posterius verlaufen: Tractus corticospinalis (Pyramidenbahn)Tractus temporopontinusoberer Thalamusstielhinterer ThalamusstielTeile der Hör- und Sehbahn (untere Capsula interna)
