Question by imrational: If humanity continues to dominate the earth into the far future, will we evolve to fill our ecological niches?
1. Genetic engineering might soon be possible and available to the rich. 2. the longer a stable civilization is in existence, the more specialized it’s citizenry become.

In the distant future, will we see specialized niches of humanity? Either naturally selected by societal pressures or developed through selective genetic engineering?

What will these different castes end up looking like?
Okay, I must have written my question badly. Humanity is dominating the planet in that we are a large mammal and we are eliminating other large species with great efficiency. I understand and agree that bacteria, molds, insects outweigh us.

By natural selection for societal pressures, I’m looking at “beautiful” people that tend to breed with other “beautiful” people; that People tend to breed according to social-economic class; etc. I’m referring to natural selection based on memes and not the physical environment.

So, let’s try it this way. If humanity continues to exist into the distant future and genetic engineering becomes available to the rich, will we eventually see humanity divurging into different species, so some can fill the societal/ecological niches that are vacant? What will humanity look like in the future?

I personally do not believe in evolution, i believe in creation.
however i do believe in adaption of a species, so who knows what the future will hold.

Ecological Niches: Linking Classical and Contemporary Approaches (Interspecific Interactions)

Why do species live where they live? What determines the abundance and diversity of species in a given area? What role do species play in the functioning of entire ecosystems? All of these questions share a single core concept—the ecological niche. Although the niche concept has fallen into disfavor among ecologists in recent years, Jonathan M. Chase and Mathew A. Leibold argue that the niche is an ideal tool with which to unify disparate research and theoretical approaches in contemporary ecology.

Chase and Leibold define the niche as including both what an organism needs from its environment and how that organism’s activities shape its environment. Drawing on the theory of consumer-resource interactions, as well as its graphical

How about you listen in Mr. Papagayos class instead of going online and trying to ask someone. LOL

Question by Jazper: What are the different ecological niches?
Do you know any websites on where I could learn about this?

Answer by marmazor
an ecological niche really isnt an area (such as boreal forest for example) but more of a way to show how an organism responds and adapts to the different resources in the area. there are alot of factors that decide which niche an organism or group of organisms occupy, but the competitive exclusion principle says that no two species can occupy the same one. Akk i’m having trouble explaining fully eheh so i’ll leave you some links, hopefully theyll do a better job than i did
