Evolutionarily, what will happen to humans and other organisms in the millenia to come?

Question

will humans and other organisms adapt to the changing envoronment,technological advances and demands, and viral outbreaks of the coming centuries? or will we all succumb to the unstable situaiton on earth and dissappear altogether, leaving the blank canvass of earth to start all over again?

Answer 1

In order to evolve, there must be enviormental changes. Since there are always mutations happening in every species, there are normally members of each species who survive enviornmental changes, and the ones without the correct mutations will die out. The surviving members of the species will pass their mutations to their children, and gradually this process causes the species to evolve. The living things of the world will continue to evolve in a way that adapts to the enviornment or they will die off. It is survival of the fitest and the weaker members die.
Humans are different. Humans, like all life, have random mutations in their genetic codes that they pass on to their children. (That is why we are all so different) But, for humans, it is not survival of the fitest. Humans have compassion for weaker humans and we generally help one another so the genes of the "unfit" are passed to the next generation. As long as both weak and strong humans are able to pass on their genes, humans will not evolve. A natural disaster or a viral disaster might change things but it is impossible to predict how we will evolve if we don't know the enviornment we will be adapting to. If we knew what the world will be like then we could predict our evolution. For example, if the glaciers continue to melt, maybe the water levels will rise so much that everyone without webbed feet will die. Then eveyone would have webbed feet. Soon there will be people born who have a gene mutatin that gives them flipper-like feet and these will out-survive the web-footed. After that maybe we will all be mermaids and mermen.
Long story short: All life will evolve according to the changing enviornment or die.

Answer 2

The fact that humans have harnessed the Earth and changed it to fit their convieniance makes that very hard to believe. There are hawks that adapt to the cities by living on the skyscrapers. If anything, we have modeled the Earth, and everyone else should either adapt, or get out of the way. We think we are the pinnacle of Darwinism, and anything that might inconveniance us is changed or removed. And as long as we think this, The whole world will advance and change, while we stay the same. In one millenia, we'll still be in our air conditioned rooms, typing on Yahoo Answers, the sam way we are now, while little fishies grow fish and rise from the sea.

Answer 3

What is going to happen is that we will have an all-out nuclear war that will destroy the surface of the earth with fire and block out the sun with nuclear winter destroying what little vegetation and animals survived the blast. All the best scientists and the politicians will be evacuated to underground bunkers. Because our government wasn't prepared for this (as usual) the hydroponics labs are nearly empty so starvation ensues. For the good of the human race, the scientists vote to eat the politicians until an adequate food supply can be established, so all the people that are left are the super intelligent. Over time and evolution, pigmentation will be lost from our skin due to no exposure to the sun; our bodies will atrophy from lack of nutrients, living in cramped conditions, and little or no exercise; our brain mass and size of the head will increase due to the scientists and their intelligent offspring dedicating their lives to discovering technology that will allow them to live on the surface again. They do eventually reach their goal and also develop technology for inter-dimensional/time travel so that they can travel back in time and study ancestors, maybe prevent the nuclear war from ever happening. That is actually what our "aliens" are, and why they have a tendency to hang out around military facilities where nuclear weapons are made.

Answer 4

Interesting question. As you should know, humans have already evolved to its max as far as physical characteristics go. Meaning Physically we are going to look the same. However, I believe in the survival of the fittest theory. Yes many humans will die as we adapt to a changing environment and as we become immune to different viruses or bacterias. But I it will get to the point that nature and adaptive evolution will provide humans with what we need to survive. I think that the rear threat for humans is, the destruction of the environment, using and abusing all the natural resources, pollution.

Answer 5

The cornerstone of Evolution Theory is "random selection". Nature and genetic material changes 100% randomly, and the new lifeforms that are strong enough to survive continue on. Note, the selection here implies a third party's action (someone doing the action of "selecting"), when no third party exists. The new lifeform either survives or it doesn't. Selection merely refers to the outcome of the extinction/survival test case. There is no "selecting" involved. "Random selection" is a specious term.

But I digress ... Evolution occurs randomly - that is the first commandment of all evolution. Hence, because all change is 100% random, there is NO WAY to predict what will happen. You might as well ask "in a red and blue universe, what will the new shade of yellow be?" You can't have yellow in a red and blue universe. You can't have determinism (predictability) in a totally random universe.

Answer 6

I like what some one said, the earlobes, and some one said in another question were going to lose are baby toe, but the thing is i dont think nothing will happen to HUMANS, but alot will happen to people, and the world they depend on, but we can pevent anything from happening if we decide to become HUMAN, and care for things and ourselves as a HUMAN should, people create more problems, for every thing they try to solve. HUMANS dont have problems, they just live

Answer 7

It's a hard question, noone knows that. In my opinion, considering that it's already obvious that aliens do exsist, they will maybe visit us in the future.
Also, my history teacher once said that when the 4th world war happens (nuclear war), in the 5th world war ppl will fight on horses and with spears. In other words, human race will be destroyed and everything will star all over again.

Answer 8

yea, we will adapt to all the pollution with stronger lungs and adapt to the increase in carbon dioxide. I do think that if we don't adapt then we will be extinct and will have to start all over again. that is before the sun explodes or earth get's hit by a comet.

Answer 9

Read Kurt Vonnegut's Galapagos. It's an entertaining look at that question.

Answer 10

Nothing is going to happen to humans. Besides why worry about it when we're all going to be dead before any of it happens!
