Mrs. Johnson's every word

Wednesday, April 13

which is more than we had in the past to help us determine which species gave rise to each other we will read ..... obe would you like to read that so your parents passed down their genes to you which they go form there parent all the way down to our earliest ancestor the more nitrogen bases we share the more related we are going got be if we look at the elephant and the shrew they are more related than we think did you know humans share 50% of their DNA with bananas the reason for that is that we have a common ancestor with bananas every living thing has a common ancestor this thing is called luca the last common ancestor but it is luca is a very simple common bacteria that has given rise to every living thing for example luca went off and formed a species that formed another species so on one of these species being the banana along the way there may have been other branching patterns and so on one of these being a human for we are more related to chimps than anything else if we go far enough back we share an ancestor with every living thing next time you eat a banana our cousin basically think of how sick you are and so we can look at DNA sequences our genes are made up of DNA as we more and also the main job of DNA is to produce proteins if we look at the at the end of the day proteins came from our DNA
break in talking
yawns
alright we good ok next reader combing the evidence thank you santi
*santi reads*
so before we had DNA technology we only had kind you know homologous structure this has been able to confirm things we know scientist were looking at these structures and were like these two animals are closely together show the this is a much so we got the panda which was thought to be closely related to the red panda we’ve all seen Turing red on Disney plus right OK anyway so the red panda they named it after the panda but the red panda is not that related to the panda pandas are more related to bears but they all have a common ancestor but the bears and the panda bears have a more recent common ancestor that common ancestor gave rise to the pandas and the bears they are also related to raccoons two of these are more related how can we tell which yes James yes James so what you saying is your common ancestor is more recent so they are more related the common ancestor between the red panda and the raccoon was 25 mill the entire common ancestor was 40 mill
“Grayson” *looks of disappointment*
alright so every were on a tree where we see one line turn into to lines that is a species so how does speciation even occur who would like to read last thank you Grayson
*Grayson reads*
girls if you are going to sit at the table you have to pay attention
so the key to speciation is isolation isolation being complexity separated from other species when we limit our gene pool to specific groups that do not have the opportunity to intermingle our book give the example of squirrel
⁠
so the squirrel on one side become an entirely different species do we think this is happening to humans well in order to have speciation we have to be isolated interesting your bring that up so within our own lifetimes we will see Elon Musk colonizing mars so we can be isolated by landscapes but the complete isolation is going to a different planet where we are going to have our gene pool here where the mars people will become martians the human race will cease to exist on day where we are the common ancestor of a future species maybe we will just go colonize some other plants we are also potentially see some speciation events like the isolated island thing the one of coast of India such as the colony there there’s on guys who decided to go and try to convince them to convert to Christianity he rode a boat out there and was shot by arrows and was probably eating should our planet allow it we will probably give rise to new species
*phone call*
goodbye obe
alright lets write
*cough cough*
*writing noises*
*Nevaeh noises*
*Grayson sniffing*
so were gonna be dumb you better be tough lets watch a video
*video plays*
*ms. Johnson sits comfortably*
*ms.Johnson looks confused*
*laughs at zonkey*
(zonkeys are cutes)
whispers
*cough cough*
*group questions life*
