  • @esraretin I will PM you with the answer to your questions.

  • @zthomasack are u a biologist? why did we lose our hairs? and why are we only intelligent beings? is there a link between the way how we look and our intelligence,using a language? whts the link between hands and smart brains? why dont chimps have a civilization? why have we waited for our current shape to be smart to invent writing? lots of mystery if u look closely.why do only we think about God? because we have sensitive hands? how?

  • @esraretin Oh, there's not a mystery in the process at all; we can observe it happening to this day. Now, do we know the specific transitions of all of the organisms ever to have existed? No, but those are merely slight gaps in the Neo-Darwinian theory of evolution.

  • @zthomasack i feel there are lots of question marks in evolution.i feel a mystery in this process.

  • @esraretin That being said, I really do not know if modern bacteria have evolved into multicellular forms as of recent, so I am afraid I cannot answer all of your question. :p

  • @esraretin ..environments, there really is not much evolutionary pressure placed on a lot of the bacteria species to evolve into multicellular forms. Evolution is really only focused on the reproductive success of the organisms at hand.

  • @esraretin There is an experiment one can perform with ampicillin and E. coli. When E. coli is placed in LB agar (an environment in which E. coli thrives) with ampicillin, normally the e. coli will die. However, if one places a DNA plasmid that randomly occurs in nature that codes for ampicillin resistance into a few of the bacteria, the bacteria with the plasmid will survive and create a genetically different population of E.coli. Also, since bacteria are thriving in their current en..

  • i have a question! which creature has evolved latest from simple multi cell organisms or single cell organisms? if they can propagate fastest then we should see slightly more complicated creatures evolved from them for example in every 1000 years or may be in every 100,000 years or in 1.000.000 years.if there arent new evolved creatures like i mentioned then which conditions did they have to evolve but havent had for at least last 1.000.000 years?

  • We watched this in my Biological Anthropology class. Thanks for the nice, simple visual for describing mutations!

  • Dear my channel's friends,touch please...
