Define human. Bio-life has around 100 trillion years time until all suns have vanished.The maximal limit of posthuman civilization though would be 10^64 years when the last black hole with operational Hawking Radiation evaporates into nothing. Unless we get reversible computing going, accessing vaccum energy or utilize metric engineering to create our own basement universi. Then posthumans might survive indefinitely.

Climate Change isn't a existential threat to human civilisation. During the Jurassic epoch we had sixfold higher concentration of CO2 and it was 15 degrees hotter than today. No poles, no reefs and yet dinosaurs walked the earth. It will lead too much misery, swallowing island and coastlines additionally the change of the hability zones will lead to a massive refugee crisis.

there are species that can breed with each other from a mechanical and genetic perspective but are prevented from mating for other reasons, be it geography, different mating seasons, whatever. Neanderthals mated with early modern humans and Denisovans despite being a different species.

Ultimately classification is arbitrary anyway. If you could differentiate humans into different species that alone wouldn't have any practical implications. Most people saying we have subspecies are trying to argue one is inferior, which is an entirely different question

[Anonymous No.12174334]

>>12170218
Not really. The definition of species itself is very, very old and full of holes, it's mainly there for conveinience's sake.
Neanderthal is considered a different species mainly due to phenotypic, geographic and time differences, but given that humanity, in Europe, America and Asia contains Neanderthal dna+ possible denisova, you could argue that our ancestors weren't the same species but we are the same species as our ancestors. Now, different species can interbreed, but the main argument with humans having no real grounds to really define race is the very poor genetic diversity we have due to a lot of bottleneck episodes (Humanity nearly went extinct quite a few times) and the fact that we all share roughly the same genetic information, with a lot of intraindividual variation. You could argue that each and every human constitute the only representant of their race, whereas you can see mice and dogs with homozygotes recessive alleles at the dozen, with careful intensive breeding.

[Anonymous No.12174342]

>>12172865
That is factually true, but you can make figures say anything if you have enough of a tongue. The main contender to not say "different race/subspecies" is mainly historical, given what happened with a pseudo-scientific racist ideology. It's true that a lot of genes affect brain development, but it extremely difficult to measure the reach of a polygenic trait, IQ does also not only depend on genetics but social background and academics too, which quasi nullify the point because if 30% of the genes do affect bran developpement, you are looking at one third of a few thousand genes, controlled with many more regulationary sequences which is way too much to control efficiently unless you make clones for each and every genes with a controlled amount of expression and epigenetic transformation. Transcriptomics is also an emerging science that further complexify this expression during developpment and adult life. You're also saying that americans are tards because they all have black DNA, and all Afro Americans have higher IQ cause they have Caucasian slaver DNA, which is fucking retarded.
I'm a molecular biologist btw, studying the expression of genes and their regulation.

It is rather troubling when science does not have proper definitions agreed upon.

By that rather fluffy definition we are back to the 1900's idea of vast racial differences where whites and Asians are of different species. Yet it is clear that interbreeding produces fertile offspring.
>but given that humanity, in Europe, America and Asia contains Neanderthal dna+ possible denisova,
It is unclear to me how much there is of either mixtures. So how much Denisovans are there in Europeans? Hard to tell. Specifics for ethnic groups are still not available from what I can see. Fun to see how Neanderthals had their good name and reputation restored from a rather ugly starting point in an era where "subhuman" was a socially acceptable term.
>you could argue that our ancestors weren't the same species but we are the same species as our ancestors.
I don't understand this.
>Now, different species can interbreed, but the main argument with humans having no real grounds to really define race is the very poor genetic diversity we have due to a lot of bottleneck episodes (Humanity nearly went extinct quite a few times)
Which? I only find the Toba catastrophe, and that was 75000 years ago when humanity had already covered the globe.
>and the fact that we all share roughly the same genetic information, with a lot of intraindividual variation.

Nature does not care about human need for definition and proper classification, deal with it.
By that rather fluffy definition we are back to the 1900's idea of vast racial differences where whites and Asians are of different species. Yet it is clear that interbreeding produces fertile offspring.
Does not contradict my argument. The temporal difference here is enormous and the ancestral Neanderthal genes you find today are from Neanderthal, meaning a different genotype acquired through speciation
>It is unclear to me how much there is of either mixtures. So how much Denisovans are there in Europeans? Hard to tell. Specifics for ethnic groups are still not available from what I can see.

It goes from 1-4% and varies with ethnic groups, European and Asians have the highest score.
I don't understand this.
Brainlet. You are a mixture of Sapiens and Neanderthal (possibly denisova).
>Which? I only find the Toba catastrophe, and that was 75000 years ago when humanity had already covered the globe.
I conceed your point and double down on it with some research, Toba is controversial, but I got that. https://academic.oup.com/mbe/article/17/1/2/975516 We still have a very interbred DNA. We still don't have all the answers, but interesting theories that make interesting reads. I oppose the paper I just gave with this.
One propose ancient bottlenecks, the other more recent ones. https://www.genetics.org/content/205/2/787
>It is strange how dogs vary so much more than humans, yet they were domesticated only 21000 years ago.

I know that I am a mixture (being European), what I didn't understand was this sentence:
>you could argue that our ancestors weren't the same species but we are the same species as our ancestors.
That seems rather contradictory.

>It is also so strange that the government doesn't make you breed with family
There was a human breeding program here in Europe about 80 years ago. It is considered not a good idea. On the other hand you find phrases such as "fine breeding" in the English upper classes, royalty has been doing selective breeding for centuries, many countries around the Middle East still have arranged marriages for power, there was Sparta (with extensive eugenics) and further back a time when (few) men had offspring and then with 17 women, and around here there have been articles that rich men marry pretty women and their families are therefore more beautiful than the rest of the population. That last one generated a bit of a storm, probably from ugly people.

Long story short, we have had forms of breeding in humans for millennia but human variation is still rather insignificant.

>>12177142
A study of birth rates and genetic relatedness found that the highest rates result from a "genetic middle ground." Meaning, people who were not to genetically the same to cause deleterious mutations, and yet not so genetically different to decrease fecundity, had the highest birth rates.

So I'm not sure interbreeding would initially produce 'very' fertile offspring. It would take several generations of two gene pools intermingling and finding a new gene-environment balance before we'd see an increase in fecundity.

Keep in mind these will be a series of cascading events that will start slow and keep ramping up.
