Evolution, Morphology and Exobiology

MUTATIONS - 2 Here is more scientific evidence clearly showing that mutations cannot produce evolutionary change. This is science vs. evolution—a Creation-Evolution Encyclopedia, brought to you by Creation Science Facts. CONTENTS: MUTATIONS - 2 The One "Beneficial" Mutation - One mutation which is touted as helpful, but which is actually as deadly as the rest Mutation Research - It is the in-depth mutation research, carried on for most of this century, which has settled the matter Mammoth Mutation Theory - As all the other theories shatter, in desperation a really wayout theory is grasped Conclusion - …

I believe that a major method of evolution occurs on allosteric regions of enzymes (which are the regions of the enzyme that are not involved in the chemical reaction). Cells have extremely complex methods of regulation that provide a buffer zone in the amount of an enzyme that can exist within the cell. When mutations that create additional copies of a gene that codes for an enzyme occur, the organism can often function just fine with some extra enzyme present because of its regulation system. The enzyme is then given breathing room to mutate until it creates an additional active region that performs a different but useful function for the cell. In this case, if the…

yup.. some states are going to incorporate controversies of evolution into their courses now. In other words, intelligent design is coming to a school near you! 45% of Americans believe that God created the world along with creatures big and small in just six days, without reconciliatory faith with darwinism. 30% of teachers felt that they were pressured by parents to either omit evolution of evolution-related topics. 54% did not believe that humans had developed from an earlier species, (a rise of 9 percent since 1994). Well, this canuck's going to Canada for post-secondary education source: (TIME, aug 15, 2005) So here's my rant: The Downfall of Sci…

Hypothetically, would there be any environments that would be conduicive to the evolution of vertebrate land-based animals with more than four limbs or asymmetric numbers of limbs? Is having four limbs almost always inherently more advantageous, evolutionarily, or is it just a case of tetrapods gaining the advantage early on, when things could have turned out differently?

evolution of new species can occur only when genetic variation occurs. but how will species evovle if it is reproducing asexually ( genetic variation cannot occur) and since genetic variation can occur only on mutations. and mutations are rare and most of them are harmful for living organisms and does not make much impact on genepool .according to this evolution site... http://evolution.berkeley.edu/evosite/evo101/IVBMechanisms.shtml "Mutation: Some “green genes” randomly mutated to “brown genes” (although since any particular mutation is rare, this process alone cannot account for a big change in allele frequency over one generation)." -----------------------…

how does a single celled organism give "birth" to a multicelled one?

well see this...http://www.christiananswers.net/q-eden/genetic-mutations.html Mutations behave like a "blind gunman," a destroyer who shoots his deadly "bullets" randomly into beautifully designed models of living molecular machinery. In all this research, not one mutation that increased the efficiency of a genetically coded human protein has been found. !!! then how can evolution happen?

Things evolve, or so I'm told, when they are faced with a problem that could wipe them out, or at least harm them. Such as trees growing taller, sharks jumping out of the water, and insects that blend into their surroundings. But haven't we, as people, attacked and destroyed about everything that could wipe us out? The way I see it, we no longer need to evolve, because of guns and pesticides, and gentic farming. Has evolution, therefore, stopped within our societies, or are we just stuck in a transitional phase, waiting for aliens or small pox to come and get us?

alright i was reading from the Chicago Tribune how a museum in EUREKA SPRINGS, Ark was putting up creationist explainations on some fossils that were being exhibited. They gave a example of a dinosaur, Pteranodons, saying that it was ""a pointy-headed flying reptile with a 33-foot wingspan, hollow bones and a bony ruffle on its skull. Visitors are told: "Each of these unique design features indicate that Pteranodons were created to fly, not that they slowly evolved into flying creatures.""" I am currently trying to come up with a evolutionist based response to explain the appearance of the dinosaur ( be warned i didn't have a good picture of the beast or the time p…

i got these paragraphs from creationist websites. how to answer them? Later Adolf Hitler indeed applied the Darwinist concept of the "survival of the fittest" to the human race. During World War II the Nazis forcibly sterilized more than two million people and began systematically exterminating people whom Hitler considered to be inferior. The Nazis justified their atrocities by rationalizing that they were doing mankind a service with "genetic cleansing" to improve the races. As long as evolution-with its implications of amorality and the survival-of-the-fittest mentality among "superior" and "inferior" races-is accepted and believed, genocide, as sporadic ethnic…

i would like to ask that can arthropods become as large as humans? or elephants? . what if all the chordates ancestors were wiped out during cambrian era , then did arthropods would have produced some large creatures or an intelligent creature? if u have any web link on this topic then post it

Im just wondering what all of you think as to the future of human evolution as in: -When a we will become a new species? -What would our apperence be? -What new traits may we develop? -How we will interact with; each other/the planet/animal/rest of the universe

I'm new around here and was trying to figure out which thread to start the plunge. I decided this one might be interesting, since it is related to a concept I play around with from time to time. My background is mostly tied to space-related activities, such as launch, human migration through space, planetary geology, etc. I'm also very interested in "big history" and futurism, and like to find ways to tie the past through the present into the future. The link below is to a Geological Time Scale I developed. The link below that is a little introduction to what in the world I'm talking about. Maybe it makes sense, maybe not. It's still an idea in the works... h…

I've been wondering for the past few days about this--evolutionarily speaking, we (humans, though it's true of everything) have traits that are supposed to help us in surviving, and, (probably more importantly) reproducing. So what, then, is the evolutionary advantage to being left-handed? Surely if there was no advantage, that particular mutation would've disappeared, but if there was an advantage it should be dominant, no? Of course, I suppose it's pretty stupid to ask for the advantages of tiny details, but I still question why we don't have toes with full movement, like our fingers, or what makes finger and toenails useful. Taste is another thing--sight, h…

Humans I think have only gotten to where we are due to our great capacity for memory...and language. Yes with those 2 things...BOOM, the dawn of man! Our instincts then were not only from our genes...but language. NO more natural selection! Now with thousands of years of recorded history to teach man his lessons; the wholeness of our difference from animal is the evolution of instinct! Whats next? Maybe a universal language? If we could read anothers mind ... then maybe would man evolve into something even better!

It looks like " congressman sorcerorston" has been doing a good rallying job on captial hill. http://www.christianitytoday.com/ct/2005/103/31.0.html

I can see some Neandrathal desperately looking for fire, and accidently creating it, or a Homo Erectus drawing his dreams and fears on some cave.. but language..how did that happen, and about when?

So far i have managed to avoid being drawn into the endless creationist discussions. As far as im concerned im not a creationist, but there is one final thought i have, for those non creationist theists (such as myself). All this data, we have been theorising, such as fossil records and the like and dna data, all comes through our senses; eyes ears etc. Now if God created the universe, surely he could make sense the data incorrectly, e.g. where there is a G in the DNA sequence we "see" a D. This may sound a bit far fetched and "crazy", but if God has tested people in the past to see how faithful they are, surely he could easily do this again to see who b…

What are your thoughts on the evolution of Australian Aboriginals. If you believe the out of Africa theory then the Aboriginals ancestors came from Africa and have inhabited Australia for over 60 thousand years from rock art paintings. But what I don't understand is their physical appearance and culture. It is like they are the most primitive human race. There tools and weapons were very basic, their art is said to be primitive, many cultures had no clothes and they never invented farming. Their face is also very ape like. I have been very curious about their evolution, and one thought I had is that they are decentants of homo erectus and because of their isola…

Can anyone explain to me what evolution is and how creation is incompatible with evolution? Most of the time, I find people debating this issue without clarfying what evolution and creation are, i.e. their principles and concepts. Thanks!

I believe in many different cryptozoological creatures, such as bigfoot. Some creatures' evolutionary history seems strange. For example, the Animal Planet did a show on the existence of dragons. I never actually watched it, but my friend and I were discussing it. During this discussion one of us asked how they would get they're wings. In animals such as birds, the wings come from arms, but with creatures like this already have four legs. We could't name a single vertibate that has six legs. Where would wings come from on creatures like this?

It seems like the blueberry maggots and snowberry maggots just couldn't keep their mouth parts off each other. What's worse is that their hybrid children have been breeding amongst each other for a hundred generations, eschewing the blueberry and snowberry, and living it up in the asian honeysuckle. They have become so estranged that they may even be a new species. Read more here

Hello, Sorry to bother you but this question was asked to me by my 5 year old and I could not find an answer. His question was:" If God created man did he create a baby or a grown-up?If it was a baby, how did he survive? (on his own) and who created God?" Not being religious I said that God was the easy explanation to creation. We read that new species (animal, fish, insect) appear all the time but is the first of all a newborn (and if so how do they survive?) or an adult? Many thanks

Welcome, creationists, to Science Forums and Debate ======================================================== Please refrain from 'drive-by heathen-preaching', which is where you make one post scorning us for our 'belief' in evolution and then bugger off. This is a discussion forum, not a statement forum. We therefore ask that you stick around to discuss your points with us. Drive-by heathen-preaching tends to merely occupy the moderators' time deleting them, and paints creationists in a bad light. Purpose of this thread This thread was written due to the number of creationists who visit this site to argue against evolution. Whilst this is perfect…

There are some people frozen under the cryogenic devices. The purpose of doing it is because they want to be revived back to humen when it is able to. So how many constituion of this work are in US? And I heard they have sucessfully brought back a dog from death to alive. Will we be able to see some humen being brought alive in near future? If so, that means it will change the system of humen nature.
