Essay on Science and Technology for Children & Students
Since the most dramatic instances of speciation seem to have happened in the aftermath of mass extinctions, this essay will survey extinction first. A corollary to is that if any critical nutrient falls low enough, the nutrient deficiency will not only limit growth, but the organism will be stressed. If the nutrient level falls far enough, the organism will die. A human can generally survive between one and two months without food, ten days without water, and about three minutes without oxygen. For nearly all animals, all the food and water in the world are meaningless without oxygen. Some microbes can switch between aerobic respiration and fermentation, depending on the environment (which might be a very old talent), but complex life generally does not have that ability; nearly all aerobic complex life is oxygen dependent. The only exceptions are marine life which has adapted to . Birds can go where mammals cannot, , for instance, or being , due to their . If oxygen levels rise or fall very fast, many organisms will not be able to adapt, and will die.
Science and Technology Essay for Class 3, 4, 5 ..
Until fossils were recognized for what they were, the (c. 541 to 485 mya) was considered to have produced the earliest known fossils, and that situation vexed scientists from Darwin onward. If animals just came into existence from nothing, the Creationist arguments of Darwin’s time may have had some validity. Darwin attributed the lack of Precambrian fossils to the geological record’s imperfection. As this essay’s previous sections have shown, scientists have filled many gaps and Darwin’s theory has held up well.
But the original Hebrew word has more meanings than that. can mean the planet, the land and its inhabitants, ground, soil, country, or territory (Zodhiates, page 1600-1601). When the late Menachem Begin and other Zionists speak of , or Greater Israel, they are referring to Israel's pre-1967 boundaries plus Jerusalem and the West Bank of the Jordan River. They are not laying claim to the Himalayas. If we understand to mean the region of the Middle East, then the story of Noah's flood does not have to cover Mt. Everest at 29,028 feet.Let the Earth Bring Forth.
The phrase "let the earth bring forth..." occurs three times in Genesis 1 (verses 11, 20 with water, 24). It does not refer to simple growth from nutrients, because this chapter is about creation. The literal meaning of this phrase matches theistic evolution better than any other creation theory! It's almost a definition of theistic evolution, which is why I put it at the top of this essay. God commanded the earth to produce animals, and the planet did so according to His command.These verses contradict the idea of direct creation of non-human life forms. Carnivores
There are several verses in Genesis that are taken to mean that animals were vegetarian until the Flood. Genesis 1:30 states: "And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat: and it was so." After the Flood, God states in Genesis 9:3 "Every moving thing that liveth shall be meat for you; even as the green herb have I given you all things."I like the idea expressed in Genesis 1:30 of God's providence for all creatures. I also like the idea of the Peaceable Kingdom, where the lion lies down with the lamb and there is no violence. We don't have a clear indication of when the carnivorous animals switched to eating meat, because Genesis 9:3 refers only to mankind. Job 39:27-30 could indicate that eagles were created as carnivorous animals, but it's not clear enough by itself. I have looked at the sharp teeth of a Tyrannosaurus rex, and they don't look like something created by an to chew vegetation. Since I understand the references to death in Romans 5:12 to mean spiritual death, the presence of carnivorous animals does not pose a theological problem. This issue is not essential for salvation. I simply don't know how Genesis 1:30 fits in with what I can observe about animals. When taken with verse 29, the two verses could be merely a description of who gets to eat what kind of vegetation (man - seeds and fruit, animals and birds - grasses and plants). I do know that verse 30 occurs in a section that describes God's providence for all creatures, and that is the faith message I can take from it.With regard to pre-history and evolution, we do not know how long satan has been allowed some measure of influence and interference in the world. The Garden of Eden sounds somewhat like a sanctuary set up by God to guard Adam and Eve against the outside world. Was there trouble and danger out there even before the Fall of Mankind?In any case, the creation account in Genesis 1-2 is incomplete. Astronomy shows us this in a spectacular fashion. I think that the biological account in Genesis is also incomplete. Who can completely describe the mighty work of creation in just 2 chapters? Not Moses, nor any other possible human author of Genesis. God Almighty rested for the only time recorded in the Bible! I think there is a lot more that happened historically than just those relatively few words in Genesis 1-2. I think a few sentences cover millions of historical years, such as in Genesis 2:7: "The time came when the Lord God formed a man's body from the dust of the ground and breathed into it the breath of life. And man became a living person."Is the Bible incomplete? Yes, John says so at the end of his Gospel, in 20:30-31: "There were many other signs that Jesus worked and the disciples saw, but they are not recorded in this book. These are recorded so that you may believe that Jesus is the Christ, the Son of God, and that believing this you may have life through his name." John repeats the "incomplete" assertion in 21:25: "There were many other things that Jesus did; if all were written down, the world itself, I suppose, would not hold all the books that would have to be written."What we have is sufficient for Faith. The details left out are interesting, but they are not needed for Faith and Salvation. So we need not worry about the Bible being incomplete. We have enough testimony, both for our own faith and to witness to the world. I don't usually grind through the beginning of Genesis verse by verse, trying to match each one individually with a scientific or historical finding. I think that that approach obscures the greater faith message of the Author.
Modern science reflects the vagueness of ..
My teachers from the first grade onward remarked on my fascination with nature. Science always came easily to me. A saw me trade my science studies for business studies in college, and that voice in my head led me to attempting to fulfil my . I left the path for applied science in the real world, and . In 2002, when I finished my website largely as it stands today, I longed to one day resume my math and science studies. Soon afterward, one of R. Buckminster Fuller's pupils remarked that my work was like Fuller's, helped crystallize the paradigm that I had been groping toward. When that paradigmatic view became clearer, I began the studies that resulted in this essay, and my efforts since 2007 were specifically directed toward writing it.

But the African Oligocene event of most interest to most humans was African primate evolution. By the Eocene’s end, primates were extinct in Europe and North America, and largely gone in Asia. Africa became the Oligocene's refuge for primates as they lived in the remaining rainforest. The first animals that evolved in the late Eocene, and what appears to be a appeared in Africa at the Oligocene’s beginning, about 35-33 mya. But ancestral to that creature was one that also led to those that migrated to South America, probably via vegetation rafts (with perhaps a land bridge helping), around the same time. Those South American monkeys are known as today and they evolved in isolation for more than 30 million years. For those that stayed behind in Africa, first appeared around the same time as those New World monkeys migrated; they diverged from . Scientists today think that somewhere between about 35 mya and 29 mya the splits between those three lineages happened. Old World and New World monkeys have not changed much in the intervening years, but apes sure have.
