The Earth nourishes life, and its churning oceans allowed complex molecules to form the first DNA. |
The Sun supports life, and gives sunlight to photosynthetic organisms to produce the oxygen that animals need. Note: This image shows the Sun as viewed by the Soft X-Ray Telescope (SXT) onboard the orbiting Yohkoh satellite. The bright, loop-like structures are hot (millions of degrees) plasma (electrically charged gas) confined by magnetic fields rooted in the solar interior. An image of the sun in visible light would show sunspots at the feet of many of these loops. The halo of gas extending well beyond the sun is called the corona. The darker regions at the North and South poles of the Sun are coronal holes, where the magnetic field lines are open to space and allow particles to escape
Nature: the wonderous glory for us to marvel, explore, strive to understand and enjoy.
Hi! I am Don Valich. My current interests are in paleontology, paleogeology, geology, ecology, evolutionary biology, phylogenetics, biostratigraphy, and "origin of life" topics. Within the field of paleontology my primary focus is on the evolution of terrestrial mammals during the Tertiary period. If I make a mistake on any article, please correct it. I would really appreciate it. All constructive comments, questions and insightful posts are very welcome.
Currently, my objecives are to research the origins of the evolutionary lineages of early mammal species with particular interests in the Cynodonts, Miacoidea, Creodonts, and all early Carnivora, such as Hemicyonidae and early Ursidae species, and I have a particular specialization in Canidae evolution. I welcome any interests in these fields, especially Canidae (dog evolution), and any challenging questions or research assignments. I also have keen interests in researching the evolution of continental crust and early land masses, and the accretionary events that formed early supercontinents, and the North American and Wyoming Craton. I am also now researching the uplift of the Colorado Plateau and the origins of the Grand Canyon via the capture, piracy, and down cut of the Colorado and Green River and their earlier initial northern course and reversal.
The theory of evolution is the central unifying paradigm of all biology - Nothing in biology makes sense except in the light of evolution [1].

My favorite animal is the Norwegian Elkhound !
Meet "Kodi" - the friendliest, gentle, shy, "insecure" but loveable, super with children - always giving kisses! - Elkhound that ever existed! Her motto is NOT "I love to be petted"; it is "I "LIVE" to be petted!!!"
