First: Do you accept the fact that through heritability and various environmental pressures, populations of animals can change over time with subsequent generations. Call it adaptation, call it microevolution but do you accept that, that mechanism for change is present and observable?
You get different breed of dogs by mating dogs with special characteristics
Yup. Humans use artificial selection rather than natural selection to choose the special characteristics we find desirable in the animal. And how do those special characteristics get passed on to the puppies? Is it through the heritability of genes?
....no. What? lol no, we know very well. Genes are heritable. How else do you think a child has features that look like their parents? Remember the Reverend Gregor Mandel who discovered the heritability of traits in the 1800's?
@Pikachu You don't agree that science explains it all? Science says you are a human being living on a planet that revolves around the sun. I don't believe any of that at all, and it doesn't stop me from living a life like yours. So, why do you need to pack all that explanations in your head?
Very small marine organisms, such as plankton, are ideal for showing gradual evolutionary change. There are many billions of them, many with hard parts, and they conveniently fall directly to the seafloor after death, piling up in a continuous sequence of layers. Sampling the layers in order is easy: you can thrust a long tube into the seafloor, pull up a columnar core sample, and read it from bottom to top (our research institutes here in New Zealand do this routinely).
Come to New Zealand and you can see a two-hundred-meter-long core taken from the ocean floor near New Zealand, presenting an unbroken history of the evolution of the marine foraminiferan Globorotalia conoidea over an eight-million-year period.
Or you might prefer the eighteen-meter-long core extracted near Antarctica, representing two million years of sediments, showing us, again in an unbroken history, the evolution of the radiolarian Pseudocubus vema
Or perhaps you’d like to see my personal favourite… a core sample that shows an ancestral plankton species Eucyrtidium calvertense dividing into two descendants from a common ancestor over 3.5 million years. The new species is Eucyrtidium matuyamai
I appreciate the opportunity you have provided for me to demonstrate the solidity and validity of Evolution by Natural Selection.
All apes except humans have 24 pairs of chromosomes. We humans are the only apes to have 23 pairs.
Evolution made a testable prediction; That somewhere in the human genome we should find evidence of chromosomal fusion. In other words, we should be able to find a fused human chromosome with the remnants of extra telomeres and centromeres.
Since the loss of all the genes in a chromosome would have been fatal to any species, scientists reasoned that if the Theory of Evolution was correct about common ancestry, one of two things must have occurred. Either two chromosomes had fused in humans’ evolutionary past, or chromosomes had split in the other apes. Using 'Occam's Razor’, which states that among competing hypotheses, the simplest explanation is most likely the correct one, the most likely event was chromosome fusion in humans’ ancestors.
Normal chromosomes have a centromere (a chromosomal locus that ensures delivery of one copy of each chromosome to each daughter at cell division.) and ends that are capped with telomeres… think of them as the aglets on shoelaces). It was postulated that if two chromosomes had fused, evidence for such an event would be found in a chromosome with two centromeres and telomeres where they did not belong. That is exactly what was found in human chromosome 2 (chromosomes are numbered by length).
It was subsequently established that the equivalent chimpanzee chromosomes contain the same genes as human chromosome 2 and if placed end to end the positions of those genes match those of the human chromosome. The same chromosomes in all other ape species also line up in the same way…. the fusion event has been confirmed.
Recently we have obtained largely complete genomes of two other human species, those of Neanderthal and Denisovans. We see the same chromosome fusion in their genomes as well, which tells us that the fusion event took place in a common ancestor.
The greatest test of any scientific Theory is in its usefulness as a predictive tool. In this case, as in many others, the Theory of Evolution has delivered
@sree251 I suppose trying to explain something simple like a yearly flu shot would be pointless to you. The virus evolves, and becomes resistant to the vaccine. You probably believe it’s a plot by NASA to put tracking devices inside people who have seen the ice wall .

I have never taken a flu shot and never had flu. Did not get vaccinated for Covid either. I am not into modern medicine. If God thought it was necessary, there would be hospitals in the forests for critters.
@sree251 Human aren’t the only ones who get vaccinated. That’s the point. And viruses still evolve. And evolution works. When was the last one you watched god come up with anything new ?
'Us' is a global body of researchers (predominantly biologists of every stripe) who collectively produce a tsunami of research literature year after year.
it's not difficult to find, and much of it can be freely accessed. If you find that too difficult, I'd be happy to make some available to you here.
All I'm reading is a lot of scientific terms translated into nonsense. I need to see actual evidence of what your saying is true, Newjaninev. Try not to run away this time, okay?
Even though a bot, you do serve the useful purpose of providing a platform for showing others the duplicity and incomprehension of the Jehovah's Witness cult.
