This post is just wrong in everything it says.Here's the bottom line. Science can only prove similarities. They cannot prove evolution from a common ancestor. There is no way to test or reproduce it. They haven't even been able to test or reproduce evolutionary processes they say happened.
Here is the bottom line. It is the task of the different sciences (!) to describe the physical world and explain it in more fundamental terms. Within each science’s field of applicability, it can prove certain claims about the physical world more or less. Chemistry can prove the stabilizing effect of the resonance of electrons in the benzene structure. Astronomy can prove the heliocentric model. X-ray spectroscopy can prove the structure of DNA. And so on. So here the post is already wrong.Here's the bottom line. Science can only prove similarities.
Who are these “they”?Science can only prove similarities. They cannot prove evolution from a common ancestor.
Good let us assume these “they” are palaeontologists and evolutionary biologists. No, they can’t indeed prove with the rigor of a mathematical poof. But palaeontologists can assign a common ancestry with varying degree of certainty, and sometimes with very high degree of certainty, like in the case of the Equidae.
No. Past events can’t be reproduced. We can’t reproduce the volcanic eruption that destroyed Pompei. We can reproduce the building of Stonehenge. We can’t reproduce yesterday’s weather. Shall we discard archaeology, history, meteorology?There is no way to test or reproduce it.
But common ancestry can be tested. It can be tested by looking at the pattern of differences and similarities that different species have among each other. This needs to have the form of a nested hierarchy. Better, we can sequence protein after protein, construct a phylogenetic tree for each different protein, and all these phylogenetic trees need to correspond. This pattern can not be explained by the Intelligent Design or creationism.
Past events are past events. But evolution can be observed both in the wild and in the lab. Plenty of experiments have been performed that demonstrate the change in allele frequency in a population under stress. See for example the experiment performed by Roy Kishony.They haven't even been able to test or reproduce evolutionary processes they say happened.
A simple and elegant way to show evolution in action was set up by professor Kishony and his team. A gigantic petri dish was divided in lanes with increasing concentration of antibiotics, from (0 , no antibiotics: 1 just enough to kill all bacteria, gradually up to 1000 x the concentration of 1). Different strains of Escherichia Coli were spotted in the 0 lane. As this lane got filled and the places for new bacteria got depleted the bacteria were pushing against the boundary of the 10 lane. Only those bacteria and their descendants that got the suitable mutations for surviving in a higher concentration of antibiotics made it to the next lane. The experiment filmed over 11 days shows clearly that bacteria can evolve a resistance to a 1000 fold stronger concentration of antibiotics than the wild type bacteria.
It shows that evolution is cumulative. Each mutation increases the resistance to the antibiotics in an incremental way (see how the growth of the culture pauses at every boundary and how the growth always start at one tiny spot).

A key aspect of bacterial survival is the ability to evolve while migrating across spatially varying environmental challenges. Laboratory experiments, however, often study evolution in well-mixed systems. Here we introduce an experimental device, ...
