Evolutionists/What exactly was the first multicellular creature? No speculation please, only facts. How did?

Question

it form? Was it aerobic or anaerobic? Are there scientific proofs available for an organism to change from anaerobic to aerobic, or vice versa?

Aali----very astute answer.

Acid Zebra---do you see by the other posts how evolutionists see themselves as intellectually superior. If you know anything of Biology I studied under Dr. Bernard Hartman. And I am one of the few who passed his class.
Why am I stupid simply because I dont believe as they do?

Im not stupid.
Only stupid people call other people stupid.

Answer 1

How can anyone who did not witness it first hand have impirical knowledge as to the whole spectrum of what the first organism was? One can only speculate about something or theorize about things one has never seen. There may be some genetic hints or scientific headway that has been made to give an accurate picture of what could have been but even the scientists are still arguing about whether certain dinosaurs were n face cold blooded or if they were warm blooded. It is all speculation as no on saw it happen.

Answer 2

As early as two billion years ago, some cells stopped going their separate ways after replicating and evolved specialized functions. (Instead of being unicellular.) They gave rise to Earth's first lineage of multicellular organisms. Red algae is a good example - 1.2 bil years ago. It is an aerobe. But earliest life of this sort is as early as 2 bill. Whether something was aerobic or anaerobic is not important. The importance is if it was unicellular vs multicellular. Unicellular came first obviously.

But if you want the answer - anaerobic bacteria developed the ability to use oxygen when it was present (facultative anerobes) and some did develop into aerobes. It depends on where the bacteria were growing. Yeast is an example.

Ok gotta go to work! Hope this helps a bit.

I put a website below to show you the illustrations of biochemical evidence scientists have found over the years.

Answer 3

It's believed to be a sponge, seriously. There are over 5000 types of sponge so one can safely assume that they work(ed) on both aerobic & anaerobic metabolisms.

The oldest discovered date back to the Precambrian Era; Between 4,500,000,000 years ago, to the first exoskeletal organisms (Cambrian Era), 550,000,000 years ago.

The other organisms after & around at that time were called Ediacaran biota, which appeared about 632,000,000 years ago. I am unsure of the metabolism type, but there are thousands of different types so one could once again assume that types used either/both aerobic & anaerobic pathways.

Dalek- "They gave rise to Earth's first lineage of multicellular organisms, such as the 1.2 billion year old fossilized red algae in the photo below."

It wasn't the first, it was one of the first (and oldest to be given a definitive taxonomical name).

Answer 4

The first organisms that existed were unicellular. How organisms then became multicellular is a big step in evolutionary terms and is under much debate.

Because the first multicellular organisms would have lacked hard body parts, they are not well preserved in fossil records[1]. Until recently phylogenetic reconstruction has been through anatomical (particularly embryological) similarities. This is very inexact, as current multicellular organisms such as animals and plants are 500 million years removed from their single celled ancestors. Nevertheless, it is hypothesized that the evolution of multicellularity could have happened in one of three distinct ways:

Symbiotic Theory
Cellularisation (Syncytial) Theory
The Colonial Theory

http://en.wikipedia.org/wiki/Evolution_of_multicellularity

Leo W. Buss (1987) in a pioneering monograph has explored the transition from unicellular to multicellular organisms in great detail, and has exemplified how the competition among cells for differential propagation by fission created obstacles to the emergence of multicellular organisms with cellular differentiation (i.e., division of labor).

Answer 5

really? I don't know either. Then again, I am a network engineer, not a evolutionary biologist. Should one be an evolutionary biologist to accept evolution?

You are asking questions about life as it existed billions of years ago. Simple life, with no skeleton or bones that could have fossilized. Much remains conjecture.

But again, if you can paint 98% of the picture using natural processes, it is unreasonable to say "god did it" for the remaining 2% and stop searching.

Answer 6

Just the fact that this is in the 'religion' section and not in 'biology' says it all.

You don't truely want an answer. You just want to point and say 'oh look, I discovered a major flaw in your theory and now everything falls down'.

Try this then:
How many slices of bread were eaten in Liverpool in the first week of may 1638?
If you can not tell me how many, with concrete evidence, video footage and three sworn witnessess, than that is concrete proof that the middle ages never happened.

That's the sort of question you're trying to ask.

Answer 7

that's like trying to identify the exact germ i sneezed out onto the handkerchief exactly four years ago at precisely 5.43pm on the 12th second. what's the bet it decomposed.

no, we don't know what the first multicellular creature was, coz we haven't found any fossilized remains of it. assuming it fossilized and we can scan the globe on a cellular level. we don't really know how it formed coz we weren't around back then with the microscope and it's not around now.

Answer 8

1) The first is not known ofcourse, the olderst ever found is is the Bangiomorpha pubescens, found fossilized in 1.2 billion year old rock from the Ectasian period of the Mesoproterozoic era.

2) dont know
3) dont know

Answer 9

Are you offering the 'semi-consistent presentation of hypothesis as certainty' as a certainty? IMHO, most of the questions are rants or reiterated popular questions, like "Does God exist?" it would be exciting to tabulate the final 10,000 questions which have been asked, and categorise them. Yep, that would pastime me for approximately one minute...

Answer 10

around 2 billion years ago,......... a primitive bacterial cell related to todays,......" Rickettsia Cell ",....... entered a larger sized prokaryotic cell, with the probable intention of using it as a food source.
However,...... that bacteria was actually able to survive within that cell,........ not by destroying it, but by devouring its waste products instead, and even replicating itself to the point where both of these cells actually became interdependant on each other.
The Prokaryotic Cell, used energy provided by the Bacteria,..... who in turn survived by devouring its waste products,....... hence a very primitive example of a multicell.
In fact,....... the symbiosis of these 2 primitive cells was so successful,....... today they're classified as single,....... but originally, their origins are multi.

On Anaerobic and Aerobic Cells,....... all primitive cells and matter, begin Anaerobic,...... taking billions of years before transitioning to aerobic.
