Supposedly if we evolved from one protozoan...A single celled life...where?

Question

did this life get nutrients...and supposedly if it we evolved from the sun and water....once it evolved into something in need of more food life...but there was nothing....no plant life...yet. How did it survive....and also how did this life form procreate without a partner?

Answer 1

AMEN!

Answer 2

=} According to the theory, the first single-celled organisms were not able to practise photosynthesis and so they acquired energy form substances around them. I don't really remember form Biology but I think it was organic compounds that these organisms "ate". However, as these organisms became greater in population, the competition for food grew and so the availability of the organic substance went down. As a result, the single-celled organisms had to find another means of nutrition and some of them evolve with the ability to practise photosynthesis.
The protozoans procreated without a life-partner through mitosis, which in single-celled organisms is exact cloning. Many organisms, including other protozoans, fungi, and bacteria reproduce by mitosis. Just in case you don't know about mitosis, it is the process through which all the genetic material in the nucleus replicates. It doubles and so the single-celled organisms divides to form two one-celled organisms exactly alike.
These organisms were able to survive because during that time, there was a lot of water in certain parts of the world. They were also somewhat resistant to some hot temperatures, but the temperature were also considerably lower than they used to be millions of years before.

Where did you get this abysmally shallow profile of life on earth 11 million years ago? Ok, picture this: A VAST ocean of primitive, one-celled protozoans, amoebas, microscopic life of a variety of types. The one-celled life form YOU'RE concerned with does not reproduce by getting togethere with a 'partner', it simply splits and replicates when it has absorbed enough nutrients from the surrounding sea of chemicals. This process goes on trillions of times over a few million years, each generation getting a tiny bit more complex than the last, mutation due to radiation causing different forms to emerge, eventually there are more complex multi-celled forms, simple, aquatic critters, and more generations, and more mutation, and more complexity emerges as only SOME of the forms survive, and those survival traits are passed down, and MORE mutation, and MORE generations and so on until you get a little fish-like creature that can breathe a little air, and it survives well, and the next generation can do it better, and over MORE millions of years you EVENTUALLY get a land-based creature that stands semi-erect and is omnivorous and if you don't get it by now, you're not going to.

Answer 4

Bacteria existed before protozoa. We believe that bacteria may have hitch-hiked on a meteor that crashed onto the planet long ago. At some point, bacteria evolved into protists (protozoa). The protists were able to eat bacteria, and other protists. Some protists even incorporated types of bacteria that could photosynthesize, (these types of bacteria turning into chloroplast) giving the protists the ability to photosynthesize. These single celled protists eventually began to live in colonies, and began to form algae. Some formed into fungus-like colonial organisms. The simplest animals are sponges, which are very similar to types of colonial protists. Some hunted other protists or bacteria food, others used the sun to photosynthesize. From here, life branched into many different directions eventually creating all the life on planet Earth.

Answer 5

There is now a theory that even molecules evolve and adapt to survive. If this is true that means that even the basic elements of life are struggling to survive and that life isn't a random occurence but the logical solution to the survival and evolution of different molecules. This doesn't really answer your question but it shows how macroevolution is possible.

Answer 6

You see, the difference between science and religion is: one claims to have the problem of existence all figured out and one claims to have a pretty good idea but are still working out the details. (Your a smart guy, I'll let you figure out which group is which.)

Just keep believing in your god. Keep your mind closed to other possibilities. Keep living your life by a mythical law. But, whatever you do, don't give evolution a chance. I mean, even when we figure it out and have proof to back up our scientific claims, will it make you stop believing in your god or will you just say, god made evolution and reinterpret some scripture from the bible to make you feel better about your faith?

Hmmmm......

Answer 7

One protozoan evolves into multiple protozoans, multiple protozoans create multiple beings and life forms depending on the exact environment they evolve in.

Answer 8

Life started out very simply, just as molecules that were able to create copies of themselves from the materials that happened to be available around them. And then mutation (just errors in the copying process) and natural selection took over.

Answer 9

If you think protozoans replicate sexually, then you must have fallen asleep in biology class. Look up some websites that explain evolutionary processes. Google is your friend, if only you will reach out and take its hand.

Answer 10

Scientists are working on that problem as we speak.

I suppose they should just give it up and follow Jerry Falwell & Pat Robertson. No reason to study the issue since "God did it."

Answer 11

Find out yourself instead of just repeating "god did it" over and over in your head like a broken record. Actually LOOK. Get real answers, not made up ones. THAT'S the point. You want answers? Find them! They're out there, but there's not enough people actually looking, they're too content with their fairy tales.
