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

Mother nature is humanities enemy.
As Mother nature is chaos
It is volcanic eruptions, earthquakes, Tornadoes, tsunamis, famine, drought, ect.
Though out of chaos does come order and rebirth

Again it was not on he brink of extinction.
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.

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.

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.

Flix wrote: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.

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.

Flix wrote: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.
