if i keep bacteria in a lab for 45 millions year then will it become dog, people say from bacteria life began?

Answer 1

For the bacteria to evolve, you'll have to present it with a sequence of changes of environment. Bacteria are evolving all the time, but unless there is something to select one type over another, all the different types will survive, so you won't see any progress. If you cut off the food supplies in different places, expose some parts to Ultraviolet, and various other things, then in about 500 million years you will have something interesting. But it won't be a dog, because you won't have exactly reproduced the series of hazards and environmental changes that gave rise to dogs. You'll have a different sort of a creature.

This has happened many times on earth, where all the creatures on earth were wiped out by a catastrophe and life had to start again at the bacteria level. The most recent time this happened was just at the start of the Precambrian era, about 600 million years ago.

Answer 2

ofcourse not.
You may think like, 4000 years old egiption parah's grave opens . What happened? They all died because of the bacterias.
45 millions years later you cant find a dog in lab but you can find a new bio - weapon there.
Note : Open it carrefuly : )

Answer 3

What matters is the conditions the bacteria you subject to.If you provide the conditions that existed 450 mn years back & favoured the evolution,you may possible discover the phenomenon.But don't you worry ; we are gradually reverting back to the same situations where humans will perish & possibly may evolve to some other form.

Answer 4

I miss being able to give questions a rating... this one definitely needs a thumbs down. You obviously already know the answer to this question is "no". The way you asked it indicates you do not believe in evolution - and have a very weak understanding of the theory of evolution.

So please, keep your creationist nonsense out of the geology section and in the philosophy/religion section where it belongs.

By the way... it took about 3 billion years for life to evolve past single celled creatures - and about another half-billion years for mammals to evolve....

Answer 5

bacteria are long living organism and they die only on
certain condition .. even if it is kept on a lab for 45 billion years it only
divides its nucleous to form other bacteria . it countines
its process for long time

Answer 6

45 million is not long enough, try about 3800 million years. remember, humans were not descended from monkeys, but creationists are closely related to monkeys.

Answer 7

even if it becomes a dog it will be a very old dog!!
