- presented by students from Dr. Roger Young's BIOL 322 Genetics at Drury University - This video shows an oversimplified and comical account of the endosymbiotic theory for eukaryotic evolution. It is widely believe that mitochondria and chloroplasts evolved from an initial symbiotic relationship between heterotrophic phagocytotic bacteria and smaller prokaryotes, some of which were highly efficient at oxidation and others which were autotrophic. These smaller organisms would have benefited from the protection and the anaerobic environment inside their host, while the latter would have received the capacity for photosynthesis and efficient energy utilization. Evidence supports this theory: mitochondria and chloroplasts replicate separately from nuclear mitosis, contain their own DNA (which is circular and has several deviations from the so-called "universal genetic code"), and have smaller ribosomes, corresponding more to a bacterial size. In sexual reproduction of multicellular organisms, the offspring of a mating receive mitochondria only from the maternal side (mtDNA). - music is "Din Din Wo (Little Child)" by Habib Koité & Bamada

The point of our movie is to explain the complex idea of the Endosymbiosis Theory with a simple video. We first define Endosymbiosis and explain how it is a product of Natural Selection. This means that in order to fully understand Endosymbiosis, one must go back to the beginning- the Primordial Earth. The conditions of the Earth back then showed us that only organisms that utilized Oxygen to make energy were able to survive. This, along with the evidence today showing how Mitochondria have separate DNA from the nucleus, prove that Aerobic Bacteria are the ancestors of today's Mitochondria. Had we not fully learned and understood the concept of the Naturalistic Philosophy and the Primordial Earth, we would not be able to grasp the evolutionary lineages that lead us to Endosymbiosis.

I know there's been some curiosity about the origin and meaning of my chosen Youtube handle. So I figured I'd shoot a video explaining the meaning of endosymbiosis. There's no beer content here, but a fair amount of introductory cell biology. Links about endosymbiosis: Wikipedia's entry on endosymbionts and the endosymbiont hypothesis: en.wikipedia.org Wikipedia's entry on Lynn Margulis: en.wikipedia.org I believe all of the images used in this video are in the public domain and free to use. If I am mistaken, please let me know and I will modify this video accordingly. Thanks for watching. Hope this clears up any curiosity. More beer videos are to follow.

The oxygen revolution and endosymbiosis: When the earth's atmosphere first existed, it was anaerobic. This non-oxygenated atmosphere soon changed as cyanobacteria released large amounts of oxygen as a result of photosynthesis. This new atmosphere was toxic to many organisms, causing them to die. However some forms of free-living bacteria were able to process oxygen. These organisms moved into others, which were unable to process oxygen, in a process called endosymbiosis. The decedents of the free-living bacteria are today's mitochondria, which can be proven by the fact that mitochondria keep their own DNA. The presence of mitochondria allows many organisms to perform aerobic respiration in today's oxygenated world.

I haven't posted an entry into the "Interview With A Craft Beer Enthusiast" series since this summer, so I decided to start it up again with Dan Harper of youtube.com I think he is the most underrated beer-reviewer on Youtube as he makes good videos and definitely knows his beer. In part one of this two-part interview Dan talks about his history with beer, how he got into the internet beer scene and specifically the youtube "beertube" community and who his favorite fellow BeerTubers are. Be sure to check out part 2 where Dan talks about his criteria for judging beer; whether taste is subjective or objective and his goals for his channel.

In my last regular vlog I ribbed Dan "The Endosymbiosis" Harper about the delay in receiving the beers he was going to send me as part of the trade we conducted. Well yesterday afternoon his package finally arrived via FedEx so I grabbed the camera and filmed what I think is the QUICKEST beer mail unboxing video ever! Of all the beers in the box there was only one that I knew was going to be in there, the rest were surprises. Be sure to check out and subscribe to Dan's channel here: youtube.com PS the Upland Brewing Pale Ale is actually one of Dan's homebrews - an "imperial mild".

More evidences: chloroamphenicol can affect bacterial ribosomes - Noobapple Summary: Im really sorry that my ideas are confusing to follow. Here is a rehash of important arguments. ======================================= So its pretty clear that mitochondria and chloroplasts were at one time independent creatures. It is equally clear that they are no longer independent. Firstly this disproves creationism outright, which says that man was created in his present form. Secondly we have a new question- what happened that changed mitochondria from being independent to being dependent? Can proteins do NEW things? Or is this impossible? Well as I show in the video with a diagram, there is a complex mixture of proteins interacting with each other. Some of these proteins have prokaryotic origin, and some have eukaryotic origin. As I showed with crytomonads, these gene interactions are even more complex with FOUR genomes interacting. We know that these complexes formed by slight modifications and novel interactions, because we know what the proteins did before mitochondria were incorporated, and we know what they did after, simply by observing the proteins and how they interact in independent bacteria and comparing them to how they are in mitochondria. So we know that proteins can change function and can form novel interactions and behaviors. Now the real question is: HOW did this happen? On one hand we have intelligent design. On the other hand we have evolution. Interestingly we <b>...</b>

References: docs.google.com Adult giant clams harbor enormous numbers of symbiotic unicellular dinoflagellates called zooxanthellae. These algal symbionts function as internal solar collectors, converting sunlight, carbon dioxide and dissolved nutrients into carbon-based photosynthates including glucose, amino acids and other substances, some of which are released directly into the bloodstream of the host clam. This symbiotic relationship provides most or all of the nutritional needs of the host clams, and allows them to grow faster and larger than conventional filter-feeding bivalve molluscs even in the plankton-poor waters of coral reefs. The symbiotic relationship between zooxanthellae and its giant clam host is established during the first week of the clam's life, while it is still a microscopic veliger larva swimming in the plankton by means of its ciliated swimming organ, the velum. Veligers consume free-living zooxanthellae cells but do not digest them. Instead the zooxanthellae pass from the larval gut (stomach) into the developing mantle of the clam. This occurs after the larval clam has settled to the reef and shed its velum, a process called metamorphosis. Also at this time the young clam may anchor itself to the substrate by secreting a mass of sticky threads (called the byssus) from its byssal gland. The byssal gland is a conspicuous bump located midway along the larval and post-larval foot. The foot and byssal gland are visible in this video. Following <b>...</b>

Very lame project lol but yeh, the guitar or amp went stupid in the middle of the song but that wont stop me Lyrics: Endosymbiosis!!! The subject of our song Thanks to Lynn Margulis And Kwang Jeon Endosymbiosis The theory of Cells And how they evolved From Prokaryotes To eukaryotes One bacterium Engulfed another They live together They became mitochondria Over periods of time. Animal cells need mitochondria For cellular respiration In Respiration Carbs and oxygen become Water and CO2 Which will be used in Photosynthesis which then becomes Carbs and Oxygen and this completes the process Then theres Margulis Who hypothesized That the tree of life Splits and converges Now back to endosymbiosis Paramecium bursaria And green algae illustrates this So does protozoans and Riticulitermes virginicus YEH! YEH! YEH!!!!!!!!! All cells need energy To produce ATP Used in the Calvin Cycle Also in the Krebs cycle Yeah! And a reasonable prediction that we can get from this theory Is that organisms will keep evolving because of Endosymbiosis!

Life on Earth 006 - Eukarya Paul Andersen discusses the defining characteristics of the members of Domain Eukarya. He starts with a brief description of the phylogeny of life on earth. He then discusses the major characteristics of eukaryotic cells. He explains how eukaryotic cells evolved from prokaryotic cells using endosymbiosis and infolding. He finally discusses the metabolism and reproduction found in eukaryotes.

005 - Essential Characteristics of Life are Conserved Paul Andersen describes three main characteristics of life that are conserved in all organisms on the planet. The universal genetic code, the central dogma of biology, and shared metabolic pathways give us details of the original universal ancestor. He also explains how eukaryotic cells gained complexity through infolding of the cell membrane and endosymbiosis.
