I'm not an expert in biology and do not know anything about
I have some questions about evolution
Is evolution fact and scientifically proven?
And is there of biologists who say that evolution is wrong?
Hello All :)
I've heard it proposed that a reason for the fine tuned nature of our universe in a way to allow the existence of complexity and life could be that the universe itself is the product of evolution in a multi-verse.
I don't want to debate around the anthropological principle as I am...
Why aren't microspheres and protocells considered as living beings? What I know is that they do reproduce and exhibit metabolism.. so they fulfill the basic criteria of living systems.
I am really confused about it!
Biologists split life into two broad categories: prokaryotes and eukaryotes. Prokaryotes are relatively simple single-celled organisms and are split into two groups (bacteria and archaea). Eukaryotes, on the other hand, are much more complex cells containing specialized compartments such as...
If a methane-filled planet or moon like Titan was pulled toward a star, as the methane warmed and became gaseous, would it be possible to ignite it, converting the methane oceans to H2O with a CO2 atmosphere, which could in turn cause photosynthesis to naturally occur?
If it's possible, it...
The first is taught universally (as far as I can make out) at school and university, that Galileo discovered that all bodies (at least in vacuum) fall at the same rate. He didn't. He read it in Lucretius' great work of Roman science "De Rerum Natura" published about 60 BC. Lucretius followed...
Brain corals, like my avatar's Diploria, get their moniker for visually obvious reasons. I wonder whether there are informed hypotheses how come they look that way.
The answer to such a question would probably be partly a morphology/pattern formation story, and partly an adaptive story...
Is there any observational data available for evolution of Hubble rate? To give some context, read the dark energy FAQ by Sean Caroll here.
"If the universe is decelerating, the Hubble constant is decreasing. If the Hubble constant is increasing, the universe is accelerating. But...
