Explain to me when we stop being our current species and become a 'higher step on the ladder of evolution' (called something else).

If you don't mind.

When our ancestors could no longer produce viable offspring with us, they will be considered a different species. (Roughly.)

One of three scenarios:
1. The "elites" and those within a communal vicinity of them will continue to gain a better education than most of the world. If this continues, as reported, these children will continue to be smarter every generation. Humanity will divide between the ugly/uneducated/sub-par and pretty/educated/smarter.
2. Science will continue at a rate wherein most difficulties plaguing humanity today and in the future can be computed and resolved. We will thereby have nothing more than to gain empathy, and spread our capacity from 1st world nations to the rest of the world. Our evolved state will be a collective humanity capable of building anything.
3. The rich are already within the capacity to select certain genomes of their children. Read result 1. Selective genomes must become cheaper for the rest of the world to catch up.

Ah I understand. So, they said niandertals could reproduce with homo sapiens (our kind), is that the gray line you said "roughly" for?

Conditioned environment imprint or somesuch I'm guessing...?

[Anonymous No.1730608]

Google speciation, for starters.

ps. there are no "higher steps" in any context except time, natural selection makes descendants better or equally well suited to their environments than their ancestors, that's all. Arguably, in humans, reproductive capability is not nearly as dependent on environmental conditions at least on the local scale, as other species are.

That'll be my next poke-around then. Thanks.

There is no such thing as a "higher step on the ladder of evolution". There is no such "more evolved" or "de-evolved". This is all pseudoscience. Our descendants will have adapted to their environments, whatever they may be like.

That's one example, yes. There is always some overlap within a genus because biology is weird. Dogs and wolves are considered different species because they have some different characteristics and are adapted to different ecological niches, but they can still often (usually?) interbreed. However, they only began to diverge ~15000 years ago, so they're still very close.

Plus, there are sometimes members of the same species who can't interbreed, so there's another reason for the "roughly."

Humanity has covered the globe. We can survive nearly on every corner of the earth. We will no longer evolve based on environment. See post: >>1730599

[Anonymous No.1730634]

a species is defined as being essentially different from another when the species can no longer breed and produce fertile offspring. when he "next step in evolution" will be identifiable by its lack of fertility with humans

Seems silly, but I also heard a (rumor) that there was a test to see if a chimp could be impregnated by a human or something. Succeeded, and they scrapped the whole thing and torched the bodies.

Sort of freaked me out.

no, i think the human species would become more and more degraded; become dumber and dumber, while our computers and machines become smarter and more complex. Our computers would conquer the stars, not our children.

But no need to worry would would be pre-occupied with all the luxuries that our technology gave us.
