Colonizing Mars: Should Humanity Prioritize Colonizing Mars or Fixing Earth?

From Africa, humans began leaving parts of Africa about 60,000 years ago, which eventually spread human populations across the globe. They eventually hooked up with Neanderthals in Europe. There was another group in Asia they hooked up with, too. I’ll have to look that up, because I forgot the name of that group. But as a result, non-African populations can trace their ancestry back to the original group of humans who left Africa during that period. Have you ever read the book called Sapiens?

So basically, some black folks decided to bounce from Africa, accidentally ran into some Neanderthals that were residing in Europe, kicked it with them, filled the bellies up, pushed out some kids, and that’s how we got here? That’s how your post reads to me Lol

Actually Phrozen, there is genetic evidence that supports his post, though.

Oh, and to Zach, yes, I have read the book “Sapiens”.

I’ve seen that book on the shelf at the local book store. Never looked through it though. Is that book true/accurate?

Interbreeding did happen. But genetic facts show that the majority of modern human DNA traces back to African populations. I’ve also read from scholarly sources that non-African populations have small percentages (about 2%) of Neanderthal DNA. This is the interbreeding evidence between Homo sapiens and Neanderthals in Europe and Western Asia. If you look at Asian populations, they carry Denisovan DNA. It’s about 5% in some parts. That was the other group whose name I forgot. That’s evidence right there that there was interbreeding with them too.

Last night I was catching up on some items I had saved in my DVR, but I had not watched yet. One was an episode of PBS Independent Lens called Space: The Longest Goodbye. It is about how NASA has attempted to research how we humans might approach a trip to Mars as the journey is long and people who volunteer to go will experience extreme isolation.

The program was a little dry at first, but became more interesting towards the second half. When it comes to space exploration, people are focused on things like "science", technology and biology.....but are humans prepared to mentally survive? NASA hired psychologists to look into just that.

Y’all ever see those documentaries about how the Egyptians, Mayans, and Aztecs had pyramid art showing aliens? I’ve seen documentaries where the artwork shows aliens interbreeding with humans/non-modern humans — Neanderthals like Zach said. Y’all think that could have happened, if there are aliens out there? Dumb question, but my curiosity told me to ask.

What sources were you using, Zach? I’m asking because this isn’t true.

If there are/were aliens visiting Earth, for interbreeding to happen, the alien life forms would need to have DNA or a compatible genetic structure very similar to humans. IMHO, this is like a big “no way”, given the differences likely to exist between life forms that evolved on entirely separate planets. And there’s like no verified scientific evidence or fossil record to suggest that humans have DNA from non-Earth species.

Some ancient cultures like the ones you’ve mentioned have myths involving “gods” or aliens coming to Earth to mate with humans. I think these stories are more symbolic than anything, in order to explain natural phenomena, not actual historic events.

How do you know, CG? What makes you so sure this is impossible and never happened?

Aww shit Lmao!

If aliens are coming to earth in 2024… going to put that UFO in reverse and get the heck away from this dumpster fire

I don’t know entirely, but scientifically, I don’t believe that’s probable. I mean, interbreeding is more likely between species that are closely related with an evolutionary connection, within the same genus. So then, tell me how is it possible that Neanderthals mated with aliens from another planet or solar system? I’m asking you that question. Waits for an answer.

I totally agree with you, winter! 💯

Where’s the proof? Earth is old as hell so none of us know what took place back in the day.

So, I’ve always been interested in my ancestry, and the furthest I can go back to actual relatives is to Turkey on my mom’s side. Sicily on my dad’s side. But I wanted to go back even further to get a glimpse of my genetic history. I have a bronze complexion, which really opened up curiosity on my part. So, I decided to go to “23andMe” where I had tests done. When my results came back, traces of Neanderthal DNA didn’t show up. Not saying there isn’t any, just pointing out that not all non-African people carry Neanderthal DNA like you posted. The article you posted, Zach, said “most” which means the amount of Neanderthal DNA varies between individuals and populations, even among those with European or Asian ancestry, which proves my point.

And then, southern European populations, including my ancestry (Greeks and Italians), have a really diverse genetic history due to migrations and interactions with Africa, the Middle East, and other parts of Europe. So, this mixture could dilute Neanderthal DNA to levels that are harder to detect. With that, ancient Mediterranean populations experienced genetic input from Africa, where Neanderthal DNA is minimal or not present at all — the reason traces of Neanderthal DNA didn’t show up on my tests. But that doesn’t mean I don’t carry traces of it, though.

But does it really matter, Zach?

Because life on Earth evolved under specific conditions (its atmosphere, gravity, water, and biochemical processes). Alien life would have evolved under entirely different environmental factors. And then, Earth life is based on DNA/RNA as the molecule of heredity, with carbon as the backbone of its molecular structure. Alien life may not even use DNA or carbon-based chemistry, making interbreeding with Neanderthals biologically impossible. What I’m saying is that alien genetic coding would be entirely different from ours. I mean, I’m picturing some hypotheticals, lol, but I don’t see a reality in it. It’s science fiction, if anything.
