I think Thor did. His weapon is excellent to kill creatures.

Would people naturally believe in God without being told about God?
No
I think the idea of 'god' evolved. People ascribed supernatural stuff to natural phenomena (sun, clouds, water...) this became polytheism (Zeus, Hera, Odin...) and now it's rather monotheism (Jahweh Allah).

As mentioned earlier, some late bloomers (for lack of a better term) may have lived otherwise heterosexual lives, with offspring.
Homosexuality imo used to be more discriminated then it is now.

I've read that environmental/cultural factors can have an effect on sexual orientation. But true sexual orientation is due to some regions in the hypothalamus.

It can be. In evolution you can have survival of the fittest gene pool....especially for animals that live in groups. I'm a fan of the gay uncle theory.

How did homosexuality evolve?
It's present in other animals as well.https://en.wikipedia.org/wiki/Homosexual_behavior_in_animals

The azolla event lasted for nearly 1 million years I think most plants and animals can adapt while the event was going on.

No.
When you measure the momentum, for example, you interact with its energy so you change the phenomenon.
19 minutes ago, Strange said:The relationship between the uncertainty of position and momentum is inherent. It is not caused be by the measurement. Nothing to do with the observer effect.
Yes but you can't know position/momentum without measuring them.
11 minutes ago, studiot said:No the HUP also applies to calculated theoretical values, where not only is no measurement ever made, but the particle may not actually ever exist at all.
Ok but this concerns mathematical logic.
16 minutes ago, studiot said:The measuring process may or may not change the particle, but any such change is additional to the HUP .
Can you measure something without changing it? What does it mean 'additional to HUP'?

No. The uncertainty is inherent to the system, whether or not you have done a measurement.
It tells you, for instance, that a particle in a box can never be at rest, because you know the particle is confined to a certain region, which gives a limit to the uncertainty in the position, and therefore there is an uncertainty in the momentum, i.e. you cannot say it is at rest.
No measurement has taken place.
Actually there was a measurement. The box can be considered to be a measuring device. By placing a particle in a box you change the uncertainty/probability.
The observer effect is the theory that simply observing a situation or phenomenon necessarily changes that phenomenon. This phenomenon can be anything.

In quantum mechanics, the uncertainty principle (also known as Heisenberg's uncertainty principle) is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle, known as complementary variables or canonically conjugate variables such as position x and momentum p, can be known. Because measuring those physical properties change the particle.
17 hours ago, Strange said:Nonsense. It has nothing to do with the observer effect. It is a characteristic of the things being measured, not the measurement.
The uncertainty is a relation of measured properties. How can the observer effect be unrelated?

That is your error. HUP says that momentum and position together are not precise, not just that we cannot measure them precise.
HUP would not exist if there was no observer effect. Without observer effect measuring a particle doesn't alter the particle and you could measure momentum and position repeatedly.
Without observer effect you would not destroy a photon by detecting it...the HUP would then not exist.
HUP and observer effect are ways we deal with reality.
4 hours ago, studiot said:Please explain to me how your measurement changed the measureand in my example where you sit and wait, doing nothing at all (no measuring) until the light arrives, by which time the event you are measuring is over.
How do you react to my explanation?

No.
This seems to be at the core of your misunderstanding. The HUP has nothing to do with the observer effect. It is a statement about the relationship between those values, whether you measure them or not.
Yes but those values only exist when you measure them, you can't invent those values. HUP is only visible when you measure a particle And measurements are subject to the observer effect.
The hup is a constraint. If phenomena did not change when measured/observed then there wouldn't be a constraint. When you measure the momentum of a particle then you alter it's energy, you change the phenomenon….But if there was no observer effect then you could measure the momentum without altering its energy and without changing the phenomenon. If there was no measurement/observer effect then particles don't know they are measured and you could measure momentum and position as precise as possible. Without measurement/observer effect, measuring doesn't alter the particle so you can repeat the measurements.

Which has nothing to do with the HUP
HUP is about the relation between 2 measurements which are subject to the observer effect. Agreed?

And when you measure a particle, you destroy the particle. Meh.
The destroying of a particle is also an observer effect...Meh

No, the laws of nature imply what we say about nature.
