Because that comet, which sent many dinosaurs into extinction, caused the mammals to go through a large adaptive radiation event that allowed the vast variation in mammals we see today, especially the variations called apes.
Hopefully that will never happen. Hopefully people will take steps to prevent that from happening. The earth has an amazing capability to cleanse itself, unless there is some terrible catastrophe, like a meteor smashing into earth humans should always be able to inhabit the earth as evolution causes ones to adapt to the environment.
If humans were to suddenly disappear, the environment would likely benefit as ecosystems would have a chance to recover. However, many domesticated animals would struggle to survive without human care. Buildings and infrastructure would decay over time.
Humans have long been fascinated by stars, often attributing them with symbolic or spiritual significance. Many cultures have used stars for navigation, time-keeping, and storytelling. Studying stars also helps astronomers understand the universe's origins and evolution.
Yes, there is still an ongoing "space race" among various countries and private companies to explore and commercialize space. This competition includes efforts to reach new milestones in space exploration, such as sending humans to Mars or returning to the Moon.
The views of creationists vary, so I will give you a very general set of beliefs.Creationists generally believe:- God created everything in present form. Evolution is not true.- The earth is 6,000 to 10,000 years old.- The complexity of DNA proves that everything was designed by God.- There was a global flood.- Dinosaurs and humans coexisted.Hopefully you get the picture by now. Obviously, science completely contradicts creationism. Evolution is very much true.AnswerTo find out what creationists believe in, I suggest you google : (1) "Answers in Genesis" to see what creationists believe, and then(2) "Evolution vs Creation" or something similar to see what scientists say and whether evolution is at all possible or not.Then make up your own mind. [Look up the definition of a religion and you will see that evolution is also a religion].
Evolution is routinely observed both in nature and in the lab. Even several speciation "events" are on record.
Evolution is an ongoing process that occurs over many generations. In humans, changes due to evolution may be slower because of factors like modern medicine, which reduces selective pressures. However, evolution is still happening in humans, but the changes may be more subtle or take longer to become noticeable.
Evolution, the change in allele frequency over time in a population of organisms, always goes on. Speciation, on the other hand, does not seem to be happening in man, but there is some controversy there. Stabilizing selection is possibly what humans are being subjected to.
Yes, just not to a very noticeable level. Evolution happens gradually, and over many generations. If you could compare us to humans a few thousand years from now (if humans are still around by then) chances are you will notice differences.
They can't and don't, they have no chance of defending themselves. Instead they are harpooned and killed with out a chance to even know what's happening. If an orca met a human one on one it would just ignore the human.
Evolution.
Monkeys were the first evolution of humans.
No.
Evolution.
no
Through evolution.
Diversity increases the chance of human survival. When a species is more diverse there is a larger chance of the population surviving an epidemic or such that might relate to biological variations in DNA or variations in "fitness" (biological variations). based on Darwin's Theories and Evolution
