As per the theory of evolution why no new beings formed any more?

Answer 1

well they are ,... but u wont see that happening coz it takes like thousands of years for one species to generate or being formed from less complex organism... we only live for average 75 years ... so it is too difficult to see the evolution theory in place right now .... plus since mankind after noticing the evolution theory has started to collect results now like 50 years back ... we still have to wait another 950 years to notice anything .. simple enough ...

Answer 2

It is believed that only a small fraction of the insects of the world have actually been discovered and many new ones are discovered each year. Who can say that they are not newly evolved?

As far as evolution is concerned humans have evolved and continue to evolve. We are now much taller, more long lived and more adapted.

Snakes are believed to have formed from lizards and vestiges of hips and legs are left in some species. This shows a very slow change.

One theory suggests that new species evolve to fill a gap that opens up such as when the climate got too much for dinosaurs and warm blooded creatures evolved.

A modern theory suggests that species only really evolve when directly threatened and that this can happen in a few hundred or thousand years.

However, there is a problem - mankind has controlled the planet in many ways to bend it to his own use and thus stabilised it in ways that probably would not have happened. Worse in some respects is that environmentalists have striven to keep the ideal habitat for some species thus ensuring they do not come under pressure to evolve!

Do not forget that much of what we see of evolution today took place over millions of years and we simply have no idea if individually involved species happened quickly or slowly. We therefore simply cannot really expect to see any new species in our lifetime.

Answer 3

One possible answer is that evolution is based on adaptation or rather overcoming adaptation with a biological change. This therefore splits the theory into two parts a slow gradual change or a rapid change (mutation) that allows the species to continue. The strongest survive and best adaptive genes emerge. Whilst the human part of evolution is quite different to other animals in that we have grown/evolved our brain to perform cognitive functions, such as construction, and also opposing thumbs which we change the environment to suit ourselves eg we think of a house and then are able to build it to protect ourselves from environmental extremes and therefore do not evolve as quickly biologically. Thomas Kuhn writes that all scientific theories are wrong eventually but that science is the best explanation at the time. everyone believed the Earth was flat, the earth was the centre of the Universe, etc.

Answer 4

Evolution is taking place all the time, but it is often a very gradual process, stemming from the arrival of new alleles into a population by mutation, and then selection forces acting upon these new alleles (an allele is a form of a gene, eg allele for blue eyes or allele for brown eyes - although the genetics behind eye colour aren't quite that simple!).
So to detect evolution taking place, for example, in humans - we're not suddenly going to see a whole generation of kids born with green skin or something! The variation needs to arise naturally in the human population, and then grow in frequency in the population, by those who have this new feature having a better chance of survival for example. So this IS taking place - there is a mutation some people possess in one gene that confers resistantce to HIV (the gene responsible for the CCR5 co-receptor) - and I'm sure you can see how, with the current AIDS epidemic, having this mutation could provide a survival and reproductive advantage!
Incidentally, someone mentioned humans coming from monkeys - evolution does NOT say ANYTHING about humans coming from monkeys!!! What it suggests, is that humans and monkeys evolved from the same common ancestor, and is that really unreasonable? Our DNA is much more similar to that of a monkey than it is to an ant's, you can see by looking at humans and monkeys that we do look more alike than either of us look like zebras - and you look more like your brother or sister than you do your classmates, dont you?

Answer 5

They are. It just takes time. One example that we can observe is the apple maggot evolving from the hawthorn fly. When apples were introduced to America, an insect that grew on hawthorn fruit was able to grow on apples. Over a number of generations, the population diverged into two groups: those that best grow on hawthorn and those that best grow on apples. Although the can still interbreed, they generally don't. They may not be separate species yet, but they are on the path. The wasps that prey on the two, have also diverged into subpopulations.

Answer 6

Darwin created just a theory, and by the end of his caree he gave up this theory, because there was a part of the chain missing.
The wine-fly has the DNA the closest to human, even the ape has the DNA more different to human than a fly. What should we learn out of this: That the evolution theory is not necessary ment to be taken as an absolute truth, it just explains that we all have something in common and we are created after the same laws of nature. It can't explain how the first living organism was created out of non-living matter. Somewhere you just have to take God in consideration as cause of all things. I agree that adaptation to different surroundings might cause change of colours from 1 species to another, even the quantity of hair on the skin. But that doesn't transform monkeys in humans because the DNA doesn't allow it. Take the example of horse and donkey. If you mix them, their "child" won't be able to make other "children". There is a law of nature that doesn't allow evolution from a species to another. The bones discovered in Egipt, which are more old than 2000 years, are the same to the bones of dead people now. The DNA is over the same structures, so they are not even more 0.0001% monkeys comparing to us...

Answer 7

The difference from species to species takes thousands and sometimes millions of years. So it is happening, just so slow you don't notice. But some viruses and bacteria do evolve very quick because of rapid reproducing. TB has changed a lot so it is resistant previous treatments.

Answer 8

They are. The reason you have to have a new 'flu injection every year is because the virus has evolved into a new form. Larger life forms take much longer but the process is going on all the time.

Answer 9

Evolution does not happen overnight,you can not see change in one lifetime,just picture how long it took man to get down from the trees to his present day.if you could see some change right now,it would be female beings borned with their left hand stuck to their left ear holding a cell phone,and their male counterparts with a remote control in their right hand.

Answer 10

judt check the IQ level of KIDS at present and compare with that of 10,20 or 30 yrs. before.
U will not say the same thing...!
