Speciation, the belief that, over enough generations, one species slowly transitions into a new and distinct species through random mutations that is genetically different in every way, is not a difficult concept to understand. Despite those who believe in it stating otherwise, due to the vast majority having their own confusion over what it is. There is nothing complex about the concept. It is really as simple as one species, evolving over time, into a new and distinct, genetically different species.
From Britannica, speciation biology:
“speciation, the formation of new and distinct species in the course of evolution. Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineages.”
The genetically independent lineages are the creation of completely new species, not variations in the same as a result of adaptation, but something completely distinct from the original species.
For speciation to occur, mutations must show the transition period between origin species and new species. Transition periods are not considered to be rapid things where fossil evidence should be lacking, yet it is, in every single assumed line.
The fossil records used to claim evidence of speciation has never revealed a single transitional period. There are no slow mutations proving one species becomes a new and distinct species over time. The gaps are millions of years. If transition fossils exist, they would have been discovered.
Lack of evidence is not evidence. Without transition fossils, there can be no transition from one species to another.
Outside of fossils, claims of speciation are used for animals and single-celled organisms that never quite reach the true meaning of speciation. A genetically distinct species originating from anything has never been witnessed, anywhere.
Feral hogs were introduced to the Americas about 300 years ago. They can start breading as young as 6 months. This gives an approximate for how many generations of hogs there have been since that time. Approximately 600 generations without a single sign of speciation happening.
Genetically, those hogs are the same as those first released. There is no distinction, despite hundreds of generations.
In 1988, evolutionary biologist, Richard Lenski, began an experiment using E. coli to prove speciation exists. E. coli goes through over 6 generations in a single day. Over the course of 30 human years, 1,643,625 years pass for E. coli. More than enough time to prove speciation exists.
On November, 11, 2019, Discover Magazine released an article by, Nathaniel Scharping, How a 30-Year Experiment Has Fundamentally Changed Our View of How Evolution Works, which stated:
“Thirty-one years later, Lenski stands in the middle of his lab at Michigan State University. He’s tall, with a jovial face and crinkled blue eyes that flash with intensity when a topic he’s passionate about comes up. In front of him is a glass-lidded chest where 12 populations of Escherichia coli sit in flasks, gently shaken every so often by the machine inside. These small containers hold the latest iteration of the experiment that has become Lenski’s defining achievement: the Long-Term Evolution Experiment, or LTEE.”
1,643,625 years had passed for E. coli during that 30-year experiment, and he still had E. coli. There was no speciation. Just E. coli doing what had always been witnessed since first discovered.
Every animal or single-celled organism used to provide a witnessed account of speciation does not show speciation, but adaptation. No matter how many generations are witnessed, every animal and single celled organism remains, genetically speaking, what it has always been.
Most people who claim to have evidence of speciation by pointing out adaptation, do so based on what they believe to be real evidence, since they have no idea what speciation really is. They have been led to believe that adaptation is speciation, and no genetic difference is required. They have been told, by smart people in authority, that it is too complex to really understand and simply take their word for it.
Those in authority who do know what speciation is have an understanding they lack any real evidence. That is what a 30-year E. coli study was done. To prove speciation exists. There should have been something completely genetically distinct from E. coli and all they ended up with was E. coli.
Without evidence, speciation cannot be a valid scientific theory. To go from hypothesis, which requires no evidence, to theory requires something to be witnessed and results replicated, which has never happened with speciation. Adaptation has, but not even a glimpse of speciation.
Science is not fact, but what is known at any given time and subject to change over time. What is witnessed and replicated in the past as a legitimate theory, can and does get proven wrong by greater knowledge.
Static universe was a perfectly acceptable scientific theory, until knew evidence proved it wrong. Big Bang replaced static due to greater knowledge and understanding. Currently, there is evidence proving Big Bang wrong and in need of being replaced by new evidence.
Fossils and what has been witnessed in nature or labs continue to show a lack of evidence for speciation. Evidence, not belief or assumptions, is all that matters from a scientific perspective. Without being witnessed or replicated, speciation cannot be a valid scientific theory and should not be taught as such. It remains, scientifically, hypothetical.
