Answer 1

Answer:

Please mark me the brainiest.

Explanation:

1. Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.

2.Alone, in all that space? Not likely. Just do the numbers: Several hundred billion stars in our galaxy, hundreds of billions of galaxies in the observable universe, and 150 planets spied already in the immediate neighborhood of the sun. That should make for plenty of warm, scummy little ponds where life could come together to begin billions of years of evolution toward technology-wielding creatures like ourselves. No, the really big question is when, if ever, we'll have the technological wherewithal to reach out and touch such intelligence. With a bit of luck, it could be in the next 25 years.

3.Some examples of the human phenotype is the use of language, having and showing emotions, creating tools to make tools, the use of fire, living in groups, creating social identities, the division of labor, using empathy, being able to distinguish between right and wrong and realizing responsibility and intentionality.

4.Dreams as memory aides

One widely held theory about the purpose of dreams is that they help you store important memories and things you've learned, get rid of unimportant memories, and sort through complicated thoughts and feelings.

5.Well, as it happens, there are others. Among physicists, it's not controversial. Our universe is but one in an unimaginably massive ocean of universes called the multiverse. If that concept isn't enough to get your head around, physics describes different kinds of multi-universe.
