In this video Richard Dawkins talks about a hypothetical situation and attributes behavior of birds to genetic changes. He goes on to say both fishing and piracy are unstable by themselves and an evolutionarily stable strategy is one when none can do better than the other. Isn't it the same case...

Yes, I agree with all the above. But my question is are these activities of humans part of evolution? She was arguing they are not. Disregarding those environmental forces which are not under human control, the cultural forces are again from the variety of traits of human genes fighting for...

Can you tell me how it can be justified if not entirely unjustified?

How is that an excuse? These traits might be more severe in those who do the destruction and you may not be inclined to do such things because your genes may not carry these traits. The population which is able to outlive and reproduce is going to spread those specific characteristics to its...

Me and my friend were talking about human activities. She said that humans are creating pollution, killing so many animals creating an imbalance in food chain, global warming etc. In short we are making it worse for ourselves and other species. My reply was whatever humans do is a part of...

Yeah..I thought the light is flashed from the elevator itself. But thanks for clarifying

No, the beam is not going to end up lower. If the elevator is moving at constant speed then it means it is at rest per se.

Thank you all. I think I kinda get it now. Thanks again

Yeah I believe this is the case. But not sure if it is as simple as this because a ball will have an upward velocity from the elevator which is not the same as in the case of a photon An inertial observer will not see any curvature. It will be a straight line for him. It is the non-inertial...

Thank you. I now understand (logically) light emitted from an elevator hits wall at the same height in that elevator and not everyone in other elevators can expect it to hit their own walls at the same height from their floor. Otherwise there will be infinite reference frames where light strikes...

This where I have trouble understanding why the guy in downward elevator can't expect the light to hit the wall at the same height from his floor. Because when the light was fired by the upward elevator, both were at same level and the photon just fired horizontally to both elevators at that...

Sorry to start this again but Let's say another elevator/earth moving down at constant velocity and the moment light is flashed, all are side by side at the same level. Now the guy in the downward elevator will expect it to hit the wall at the same height from his floor as it was fired but it...

Wow. That was clear as crystal. Thank you.

I am not sure if I understand that. Let me clarify my assumptions. Let's say I am in an accelerating elevator (upwards) with a meter stick on two sides of them standing upright and i flash a light from the top of one to the other. I will observe the light to hit the other some where below the...

Are you saying that the path of the accelerating elevator itself is bent from inertial standpoint?
