Aspidoscelis uniparens, common name being the desert grassland whiptail lizard. I don't know enough about their evolutionary history to know how long they have thrived, but they are an all female species that resulted from hybridization between species with two genders. This hybridization not only resulted in them being unable to breed with either parent species, but it changed their reproduction method as well.
Lol
Living organisms maintain homeostasis, are composed of cells, undergo metabolism, can grow, adapt to their environment, respond to stimuli, and reproduce. Plants do all of these things, and are thus alive.
Here you go - a marine mammal that was first identified 172 years ago - so has thrived for at least that time, and probably hundreds of years longer (unless it's discovery was a remarkable coincidence), is an Atlantic dolphin, the Clymene dolphin (Stenella clymene). It has been shown to be genetically a hybrid of the spinner dolphin and the striped dolphin.
NOT good criteria. As I said, by those conditions, a rock is alive.
-_- rocks aren't made of cells, so no.NOT good criteria. As I said, by those conditions, a rock is alive.
No, humans did not make this hybrid. We only realized something was off when people noticed that all collected specimens were female.Thanks. Did human make the hybridization?
I've already expressed that I have no idea when that hybridization event took place. Heck, it could have been multiple ones for all I know. There are multiple lizard species that are all female that arose this way, so I would not be surprised if at least one of them had existed for thousands of years.When was it made?
-_- we don't know that for sure about anything, dude. Species can persist for millions of years and then all suddenly die off within just a few years as a result of environmental changes. We do know, however, that they aren't going to widespread become infertile, if that's what you are curious about. Even if we had discovered them right after they started existing, too many generations have passed with viability maintained for them to be hindered by that. They are also fairly adaptable, so they probably won't be going extinct any time soon.How do we know if they would still exist thousands of years later?
-_- it's certainly not due to the inability for white rhinos to reproduce. Overhunting, dude. Northern white rhino, a specific subspecies, is most likely going to go extinct. 3 individuals left, 1 male and 2 females, and the male is dying. Artificial insemination could be tried, but I doubt conservation attempts at this point will be able to save them long term.BTW, I just read that the last white rhino is dying.
-_- rocks aren't made of cells, so no.
-_- we don't know that for sure about anything, dude.
Rock has rock cells.
.... really? You say you teach geology, so you should know that rocks have MINERALS NOT CELLS!
Minerals are the cells of rock.
Just the opposite.Allegorically, yes. Technically and scientifically, no.
Just the opposite.
they don't.Rock has rock cells.
they don't.
cell definition: the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
Rocks contain no cells that fit this description. They don't have phospholipid membranes. They don't have genetic material. Rocks do not have cells.
Speciation in ReverseOne worldwide evidence in the sedimentary rock record is how fossil lifeforms show mature Speciation, and zero fossils that disproves Speciation.
In the fossil record, out of billions of fossils unearthed, is zero transitional fossils. Zero fossils that by morphological change prove evolution - evidence of one lifeform changing into another higher lifeform.
There is zero fossils that show life morphologically changed on Earth in sedimentary environments which show the Grand Picture of evolution of life from simple to complex.
All a paleontologist has is the observable evidence in the sedimentary rock layers srarted as the most simplest life and through time fossils that become more and more biologically complex over time and depositional history.
In Creating the Earth, God could have used geologic time to first Create simple life to exist and as geologic time progressed at select times Create more complex Species of life. And incresed the the complexity of each Species over geologic time, displaying an Earth with a fossil record we observe today - zero transitional fossils.
By scientific evidence the fossil record proves Speciations over time.
Get use to it, and start the change that Speciations was produced over time.
In another view, when Earth was Created it showed a natural history of Speciation of life over time, as He would have done if He chose geologic time and natural processes to develop the Mature Earth we now see. A Creation with an Apparent-Mature Age.
Fine, then DON'T be sure, at all, that human evolved from ape.
And in this thread, DO NOT be sure that evolution makes speciation.
I disagree.Humans are apes.
Really really wishing something doesnt make it true.
