Champlain biography

shared by lopez5891 on 24 Nov 14 - No Cached
  • Samuel de Champlain was a French explorer and cartographer best known for establishing and governing the settlements of New France and the city of Quebec.
  • French explorer Samuel de Champlain was born in 1574 in Brouage, France. He began exploring North America in 1603, establishing the city of Quebec in the northern colony of New France, and mapping the Atlantic coast and the Great Lakes, before settling into an administrative role as the de facto governor of New France in 1620. He died on December 25, 1635, in Quebec.
  • Samuel de Champlain was born in 1574 (according to his baptismal certificate, which was discovered in 2012), in Brouage, a small port town in the province of Saintonge, on the western coast of France. Although Champlain wrote extensively of his voyages and later life, little is known of his childhood. He was likely born a Protestant, but converted to Catholicism as a young adult.

  • Huge meat-eating, land-living dinosaurs evolved into birds by constantly shrinking for over 50 million years, scientists have revealed.

      Gigantic dinosaurs evolved into the small birds we know today! Scientists think that dinosaurs evolved into birds, now people also think that dinosaurs used to have feathers! Big meat eating dinosaurs such as the Spinosaurus and T-Rex may have evolved into the modern birds we know today!

      New Paraphrase: Did you know that dinosaurs, such as the Tyrannosaurus Rex and the fearsome Velociraptor became smaller, and after 50 million years, we now think that... 
  • Previous work has shown that theropod dinosaurs, the dinosaur group which included Tyrannosaurus rex and Velociraptor and gave rise to modern birds, must have decreased in size at some point in their evolution into small, agile flyers.

      Now, work has shown that two legged dinosaurs including T-Rex and the fearsome Velociraptor gave birth to the birds we see today!

      The University of Adelaide, wonders a lot about dinosaurs... They found out that dinosaurs such as Spinosaurus and Utahraptor made the birds we know today! 
  • But size changes frequently occurred in dinosaur evolution, so the research team members, led by Mike Lee, from the University of Adelaide, Australia, wanted to find out if the dramatic size reduction associated with the origin of birds was unique. They also wanted to measure the rate of evolution in dinosaurs using a large data set

      Research indicates that dinosaurs constantly changed, the University of Adelaide wants to find out what makes the gigantic size changes? They found out that the evolution by dinosaur is unique and amazing!

      The University of Adelaide also wants to measure the the frequency of dinosaur evolution!

      The U.O.A (University Of Adelaide) wonders, "how can something so big turn into something so small?" this is due to new eras, and the evolution of dinosaurs & birds!
  • ...9 more annotations...
  • They found that the dinosaur group directly related to birds shrank rapidly from about 200 million years ago.

      Scientists found out that a dinosaur species related to birds shrank in a short time and probably turned into the birds we know today!

      Dinosaur species related to birds, shrank in a short period of time! We know believe that they turned into the birds that we're familiar with today! 
  • Theropods shrunk 12 times from 163kg (25st 9lb) to 0.8kg (1.8lb), before becoming modern birds.

      Really big dinosaurs started shrinking and their weight decreased slowly..
  • The researchers found theropods were the only dinosaurs to get continuously smaller.

      Scientists now know that the two-legged dinosaur species were the dinosaurs that frequently got smaller! 
  • From this analysis they produced a detailed family tree mapping out the transformation of theropods to their bird descendants.

      We now predit that the two-legged dinosaurs transformed into birds!
  • It traces evolving adaptations and changing body size over time and across dinosaur branches.

      We now think that dinosaurs adapted into transforming into birds little by little! 
  • The researchers concluded that the evolution of the branch of dinosaurs leading to birds was more innovative than other dinosaur lineages.
    • jaime5789
      jaime5789 on 05 Nov 14
       
      We conclude that, dinosaurs probably changed into birds! 
  • this sustained shrinking and accelerated evolution of smaller and smaller body size allowed the ancestors of birds to develop traits which helped them to cope much better than their less evolved dinosaur relatives.

      Dinosaurs were getting smaller they developed traits to survive. 
  • The researchers believe that miniaturisation and the development of bird-like traits had a joint influence on the evolution of the dinosaurs into today's birds. Professor Michael Benton, from the University of Bristol's school of earth sciences, said: "This study means we can't see the origin of birds as a sudden or dramatic event, with a dinosaur becoming a powered flyer overnight. "The functions of each special feature of birds changed over time - feathers first for insulation, and later co-opted for flight; early reductions in body size perhaps for other reasons, and later they were small enough for powered flight; improvements in sense of sight and enlargement of brain - even a small improvement in these is advantageous. "So perhaps it's a long-term trend associated with deputation to a new set of habitats, in the trees, to avoid predation, and to exploit new food resources."

      Researchers now think that the shrinking of the dinosaurs was what developed dinosaurs into todays birds! Professor Michael from the University of Bristol says that we can't study the era of birds, just like that...

      This is a long process that didn't just happen like that, you sleep, you wake up and you're a bird, no! Its a very difficult process! 
  • "Birds evolved through a unique phase of sustained miniaturisation in dinosaurs," Mr Lee said.

      Birds evolved due to the dinosaurs becoming smaller!
