Motherless babies possible as scientists create live offspring without need for female egg

Post  dirge on Tue Sep 13, 2016 11:57 pm

First topic message reminder :

Motherless babies could be on the horizon after scientists discovered a method of creating offspring without the need for a female egg.
The landmark experiment by the University of Bath rewrites 200 years of biology teaching and could pave the way for a baby to be born from the DNA of two men.
It was always thought that only a female egg could spark the changes in a sperm required to make a baby, because an egg forms from a special kind of cell division in which just half the number of chromosomes are carried over.

As Mother nature is chaos
It is volcanic eruptions, earthquakes, Tornadoes, tsunamis, famine, drought, ect.
Though out of chaos does come order and rebirth
Have you just contradicted yourself there didge???

About a third died, that is no where near extinction.
You are also wrong about land, the earth has actually gained more land, than lost to the sea and many areas are being created as nature reserces.
You just keep offering poor excuses not to use something so great it can save endangered species.
You may not see anything with decline, but there is methods on this that calculate.
Yes and the reserves won't last long, people aleays come first even if it destroys habitat and species."
There was a six year volcanic winter followed by a instant 1,000 year Ice Age after Mount Toba erupted .
Genetic evidence suggests the population fell to about 10,000 adults (between 50 and 100 thousand years ago).
[solated groups survived mainly in Equatorial Africa.
Toba may even be responsible for the 'race' differences apparent today because of the isolated groups having their own particular genetic characteristics re inforced by their very isolation.

You are just too much of a pessimist, but at least you have now found the timeframe I was talking of
There is no such thing as races in humans biologically
Why does skin dfinition and facial features make people think humans are different races?
Based on that, do you classify blondes or blue eyed people as a different race?
How about amber coloured eyes?
The envoironment was key to the physical differences we see in humans today

not my words - maybe the scientists use the word instead of some long winded various ethnic diverse groups or something.
Please don't make out I have suddenly seen the light and am confirming something you said, you didn't agree there was a genetic bottle neck.
So you don't believe that a group of people isolated from other groups perhaps for anything up to 100 thousand years would not have a similarity to one another and have particular genetic traits passed on - really. You can see strong genetic traits in families today even though they have not married within their own families.

They are using the social constructs devised to define people wrongly into racial groups
If we did not classify people into races as a social construct
Racism would have no bases to exist and be argued off.

Think about that

They are doing nothing of the sort - its used as a defining term. Just about everyone of every colour talks of their 'race'.
All people may have derived from one source but a number of different branches came about and thrived for a while long enough to have physical differences then they were either absorbed or wiped out. Therefore all people that developed outside Africa now have a genetic mix that you will not find in Africans that have no European input.
So surely humans may not be different races as such but subspecies as in cats big and small etc.

Oh so you are now speaking for them and what they understand?
Please show me these correspondents they have we you to prove your claim?

You need to read the link, bcause your claim above is gibberish.

I shall post the important parts for you.

Science highlights these similarities in our embryonic development, physiology (our organ-based systems), biochemistry (our metabolites and reactions), and more recently, genomics (our genetic makeup). As a molecular biologist, this last one is indeed the most important to me — data show that the DNA of any two human beings is 99.9 percent identical, and we all share the same set of genes, scientifically validating the existence of a single biological human race and one origin for all human beings. In short, we are all brothers and sisters

Biologically speaking, one clear example is that most diseases afflict all of us — diseases like cancers and cardiovascular and neurological disorders, as well as viral, microbial and parasitic infections. Obviously, there are differences in how individual humans respond to various diseases or infections; some never suffer from cancer and may be immune to assorted infections. This may be due to factors such as diet, exercise, overall health or environmental conditions. However, the fact that a human population, irrespective of geography or ethnicity is susceptible to the same diseases, coupled with the existence of multiple pandemics, is a clear indication of how identical we are.

Genetically speaking, studies have shown that there is much greater genetic variation within a given human population (e.g., Africans, Caucasians, or Asians) than between populations (Africans vs. Caucasions), indicating that human variation cannot be subdivided into discrete races.


What astounds me the most is why you are so convinced that there is racial differences?
Whn there is none, that leads me to believe you have a motive to why you do.
Now that would b far more interesting to understand when the science shows and proves we are one human race.
Even the influx of Neanderthal breeding, is so minute that it effects mainly health conditions we find inherant in some humans today
That though does not make for a new race.

Didn't say they were NEW races or even separate races.

At most I spoke of sub species. The word race was used by the scientist explaining what is thought to have happened with the isolated populations who would have been isolated for some time and probably because of this would have certain genetic characteristics enhanced - eye colour, skin tone etc by only having a restricted gene pool at that particular time. A particular clan in this situation would share many physical characteristics as some families do.The article also mentioned that People in Africa have more genetic diversity than  the whole of the rest of the world.

What a load of drivel, sorry, enhanced, how exactly?
And what sub species are you talking of?
Again as already shown you will find more variation in the nation of Europe, than you will between Africa and Europe.
So myabe you can tell me how having fair skin is in fact an enhanced evolutionary advantage being as it makes people more susceptible to skin cancer?
The problem with the nonsense you are spouting is the divrsity is so miniscule as to amount to very little, which does not quanity as a dfifferent race let alone a species. When are you going to grasp biologically there is only a human race?
Why again are you so convinced or what to believe they are different?
I can tell you and it comes from the age you were born into.
That is where the problem stems from

By working with mice, the team were able to produce healthy offspring while bypassing the normal procedure of fertilising an egg cell with sperm.
This is the first time that the process has been achieved without the need to clone.
The extraordinary result means that sperm could potentially be fused with ordinary cells derived from skin or other tissue to create viable embryos.
It also raises the possibility of ethically questionable applications that turn nature on its head by doing away with the female side of reproduction.
Gay men, for instance, could have babies with each other, and a man could even fertilise his own cells to produce offspring containing a mixture of genes inherited from him and his parents.

More realistically, the technique could allow women whose fertility has been wiped out by cancer drugs or radiotherapy to have their own children.
While eggs can be frozen before cancer therapy and later fertilised in an IVF clinic, currently nothing can be done once they have been lost.
Conception using sperm and somatic cells would also aid the preservation of endangered species, since it avoids the need to recover eggs.
