• Atheists and religious people, will the atoms of all individuals be reused over a long period of time?

    Best answer: The atoms in living things are usually recycled by scavengers and decomposers, except in rare cases when animals die in an environment that is hostile to microbes such as the extreme cold or extremely dry environment. Eventually the sun will run out of fuel and it will expand, become a red giant, in the process... show more
    Best answer: The atoms in living things are usually recycled by scavengers and decomposers, except in rare cases when animals die in an environment that is hostile to microbes such as the extreme cold or extremely dry environment. Eventually the sun will run out of fuel and it will expand, become a red giant, in the process destroying the earth and everything living. When that happens, all the atoms will become space debris. They will not disappear because of the conservation of mass and matter. whether they will be re-used is another question.

  • How long does it take for evolution to use mutations to create a whole new species?

    Best answer: That is a subject of debate among evolutionary biologists. We simply do not know. It is also an area of active research. The only real way to find out is to look at the fossil record, but the fossil record is notoriously incomplete. According to the theory of Punctuated Equilibrium, it is likely to take less... show more
    Best answer: That is a subject of debate among evolutionary biologists. We simply do not know. It is also an area of active research. The only real way to find out is to look at the fossil record, but the fossil record is notoriously incomplete. According to the theory of Punctuated Equilibrium, it is likely to take less than 5000 years, which is the limit of resolution between different layers of rocks. No biologist thinks that it is possible for a new species to evolve in a single generation, excluding the fact that polyploidy can in fact result in instant speciation. That means if a diploid species gave rise to a tetrapoloid species, it can take as little as a single generation since a diploid species cannot interbreed with a tetraploid species.

    It has been around 11,000 years since the end of the last ice age and the mini-ice age of the Younger Dryas. There are some desert-adapted snake species (namely Lampropeltis alterna or gray-banded kingsnake) currently living in the Chihuahuan Desert of West Texas. The Chihuahuan Desert did not exist before the end of the last ice age because it was wetter and the area was covered by woodland. That means this species only evolved since the Chihuahuan Desert formed starting about 13.000 years ago. It is doubtful that this snake took the entire 13,000 years to become what it is today. It may take as short as a few decades or a few generations for the snake to evolve into its current form .

    Similarly the desert pupfish of Death Valley in California did not exist during the last ice age, since Death
    valley was a glacial lake during the last ice age, instead of the hot and dry desert valley that it is today. That is another example of a new species evolving since the end of the last ice age. the old way of thinking was that a species gradually evolves into a new species, but that view is inconsistent with the need to adapt quickly to the environment. If woodland turns into desert within a few thousand years or less, for example, a species that must take much longer (e.g.100,000 years or more) to adapt to the new environment would become extinct without any descendants instead.

  • What organ creates bile and what does bile do during digestion?

    Best answer: Bile is synthesised in the liver and transported to the gallbaldder. It is released by the gallbladder into the duodenum. It emulsifies lipids. That is, it ensures lipids exist as small droplets which do not coalesce. This ensures the lipids have a large surface area for lipases (enzymes) to hydrolyse them.

    A lot of creationists think that certain evolutionary problems are supposedly "intractable". That there's no possible way that they could have happened naturally.

    A lot of creationists think that certain evolutionary problems are supposedly "intractable". That there's no possible way that they could have happened naturally. For any or all of the ones I list, or any others you've noticed, can you give me a short, layman-level explanation for how it could have happened without requiring a miracle? 1. Abiogenesis (which I know is technically a different question from evolution, but creationists complain about it a lot) 2. The evolution of flight (especially avian flight) 3. The evolution of multicellularity 4. Sexual reproduction (the usual creationist argument here is "you'd need a male and a female to evolve at the same time, in the same place", or something like that) 5. The evolution of any complex organ or structure with many parts (eg the eye, the bacterial flagellum)
