The "furnace" is still working, the selection environment changed. Alex

Biologically speaking evolution is just the change in gene rates on the population. For a biologist, evolution is just change, never improvement. There is too much misconception on your knowledge to point out. Think an animal as a bag o genes, if they can pass to future generations their...

On 82’s Fabre paper they use a group of 100 molecules. I find some recent data showing that using a single organic molecule and given heat to then you will generate electrical current. That’s can show thermal energy given to a single molecule will excite the electron field...

If I understand right the links that you post, when you individualize in terms of a single atom, a coherence/decoherence due to clash between quantum and classic mechanics will arise. Some people suppose that some coherent behavior of solids will arise from decoherent interaction between the...

If I give kinetic energy to a body, they will accelerate and this new velocity in the same frame of reference will be an increase in inertial mass. So, energy can be converted in inertial mass. I can increase and decrease inertia given or taken energy to a body.

Updating the thought experiment. Instead of using an iron ball and give kinetic energy and thermal energy, and leave then in cold space. What happens if the subject is a single iron atom? If I give heat to a single iron atom what happens? They can’t have internal molecular movement. Alex

Anyone that already worked with lab mice can see that behavior have some genetic component. Lab mice are made to have exact the same genetic material. If you compare two separate lineages C57B6 an NZW, they have very distinct behavior. This means that genetic play a role in behavior. How...

Plants really need light, in total darkness a seed could survive of their reserves, but when energy is gone they will die. In absence of light plant will estiolate, means that the hormones will prefer growing in length. That’s a normal behavior to a seed growing inside dense foliage in the soil...

You are right guessing is only part of science, first you need to see a phenomena, after you make educated guesses (hypothesis), after you experimentally test your guesses and if everything goes well make a theory or go back to phase 2, guessing. Water isn’t a simple molecule because they are...

I am just trying to figure out some basic principles and avoiding complicating when is not really necessary. If I am guessing right this anomalous water expansion will be due to crystalline arrangement of water molecules.

Sex has a stronger selection factor than just sexual mechanics. The generation of genetic diversity is the reason sex separated individuals are so successful. Sex mechanics, or how individuals exchange genetic material is a know cause of speciation.

Unfortunately, I am Brazilian and English isn’t my native tongue, I am just struggling to be understood and trying to improve my English like you. Maybe a native speaker can correct me too.

In giving energy to a molecule I know that the electronic energy levels will increase, making some electrons jump from their orbit, did is this electronic jumps that are responsible to increased molecular motion? The heat wave will increase energy level of electrons making then jump from one...

In my simple thinking, matter has some properties that make molecules liking to be together. The likeness to be together will depend on atomic properties of molecule, on the think experiment I just use pure Iron because is a simple chemical element and all molecules will share the same...
