As I sit here watching my daughter’s pug play with my Boston bull, I wonder just how clear our idea of species is? Herto man, Neanderthal, Rodesinsis, and others are found over wide areas going back to the earliest Homo Sapiens some 206 k years ago in China no less. The oldest date for Homo Sapiens I’m aware of for Africa is 160 k to 190 k for White’s Awash discoveries.
There are lots of egos involved in human origins research. There are also complications by folks who don’t believe all “people” are human. Am I a Homo Sapiens Sapiens or some lesser creature. It all depends on who is making the definitions.
I’ve always thought there’s a strong chance all these ancient hominids are just variations of the same species. I really think a person could recreate a neanderthal or a cro magnon with a breeding program of existing living human beings. Just round up all the individuals with neanderthalish traits and start selectively breeding them. In about 20 generations you will have one.
Since by the reproductive tests, humans are related enough there has not been found a sub-group that could not produce viable offspring mating with members of any other sub grouping, a better question might be (and this will blow your mind) am I entirely human, or are the lines blurred in other ways?
Plant RNAs Found in Mammals
MicroRNAs from plants accumulate in mammalian blood and tissues, where they can regulate gene expression.
From an embedded link in the above;
Exosome Explosion
These small membrane vesicles do much more than clean up a cell’s trash—they also carry signals to distant parts of the body, where they can impact multiple dimensions of cellular life.
Which in light of how humans also are said to have more abundance of cells of other microscopic life, than they have of their own larger-celled human body cells, makes me wonder if instead of saying, "hello, my name is --- " a person could say, "hello, you are speaking with the spokes creature portion of the colony named [insert name here].
Now, it's about time to go tell a little bite of lunch, and another cup of coffee or tea, "you will be assimilated. resistance is futile" hehheh....
