Rapid Evolution Changes Species In Real Time
“I wanted to watch evolution happen,” says Reznick, now an evolutionary biologist at the University of California, Riverside…He transplanted guppies from a site where they had to fend off cichlids, an aggressive, wide-mouthed fish, to a new site with no predators and no other guppies. Reznick also introduced cichlids to guppy sites without predators.
A century earlier, Darwin had assumed that evolution takes tens to hundreds of thousands of generations to produce new species — a plodding path so slow it is essentially invisible…
[Reznick] found that within four years — a mere six to eight generations — male guppies had significantly changed their reproductive patterns. Those transplanted from a high-predation site to a stream without predators were larger, matured later and reproduced more slowly. Where Reznick had introduced predators, the guppies adapted by maturing at an earlier age. Survival became a race to produce more babies.
“The risk of death alters the ways organisms allocate resources for survival,” Reznick says.
Researchers who once assumed evolution required millennia are documenting species adapting in mere decades, or even shorter time frames. Mosquitoes that colonized the London Underground in 1863 are now so different they can no longer mate with their above-ground relatives. Chinook salmon from Alaska to California needed just a human generation to become smaller and shorter-lived after an increase in commercial fishing in the 1920s. Adaptation is happening right under our noses, in our lifetimes.
“Only time will tell whether researchers’ current arsenal of technologies is enough to untangle the complete story of human evolution.
“Only time will tell…” That is just loaded with implications. Time is defined by deterioration, not increasing complexity. Time is defined by death. And Evolution is attempting the impossible – resurrecting the dead from the remains of the living.
Perhaps novel technologies —such as paleoproteomics, a nascent field that aims to reconstruct ancestry from fossilized proteins, which are more durable than DNA—will help researchers “push further back in time.”
Technologies analyzing proteins can’t be applied to true fossils, which are stone, but other ancient remains which are, however inaccurately, called fossils.
- amber-encased insects, popularized in Jurassic Park
- organic remains preserved in ice. Interestingly, two of the animals found in Siberia are known to have choked to death on mud before being flash-frozen.
Mammoths are some of the most famous creatures of the Ice Age and rightly so...they continued living until at around 1700 BC, the same time the Bronze Age began in China, the Indus Valley Civilisation collapsed, and Hammurabi lived and died…
This one…lived 39,000 years ago…
This one, along with all the other organic specimens, was dated by the carbon-14 method which is known to be flawed.
The same skin of a mammoth was sent to two different labs for carbon dating…the results differed in each test, in one case the results varied by more than 14,000 years. This test exposed error rates as high as more than 32%, which of course is well beyond any meaningful scientific perimeter. In the end, scientists pick the dates from their tests which best fit their evolutionary guesstimates of age.
Hundreds of large mammal species disappeared during the transition from the last glaciation to the present interglacial period, from around 50,000 to 5,000 years ago…
We are using large compilations of carefully audited radiocarbon dates for each mammal species to help us reconstruct their Late Quaternary distributions.
Note the excessive explanation:
- carefully audited
This indicates awareness that radiocarbon data is worthless in terms of accuracy, only used to bolster an a priori biased Evolutionary model with Uniformitarianism.
One time frme we can deduce for certain is that extinction of species happens rapidly.
There is outstanding evidence that geological disruptions responsible for fossil formations occurred within historic civilizations.
Numerous maps discovered in the past are clear indications that the story told today by scholars is incomplete…
Zeno Map. Published around 1380…depicts Greenland free of glaciers, meaning that somehow, someone charted it prior to the Ice Age.
The Hadji Ahmed map published in 1559. A complete and perfect map…accurate delineations of the western coast of Northern America and Antarctica…a land bridge connection Siberia and Alaska, indicating it originated from a time when the bridge was still present.
King Jaime World Chart…created in 1502…depicts parts of the Sahara Desert with fertile land, huge lakes, rivers and what appear to be ancient cities.
The Oronce Finé World Map created in 1534…displays features of Antarctica…rivers, valleys, and coastlines while also depicting the approximate location of what is the South Pole today.
Some rocks and minerals can only be created under certain conditions. An example of this is the coal deposits found in Antarctica…an environment with organic material and warm swampy areas is needed.
We can therefore deduce that Antarctica was once tropical. By looking at a geological layout of coal deposits on earth, we can also deduce the alignment of Antarctica when there was one single landmass, one occurrence of which was called Pangea.
Further evidence of catastrophic formation of fossils is found in the distribution of fossils’ flora and fauna prior to the literal earth-shattering breakup of Pangea. A small sample is shown below.
Note, if we swing Antarctica and Australia to the upper right of this graphic, the distribution of the pre-breakup flora and fauna lines up in a much more logical manner. This idea is supported by the layout of coal deposits from ancient flora which are also found in Antarctica. Just a thought, but it seems as scientific as the evidence for Pangea.
when a glacier moves past a smooth rock, it leaves behind deep scratches and deposits sediments that it has collected which can be identified, dated and traced to its original place…the Palaeozoic glaciation…left scratches on rocks, which today are several continents and far away from each other.
Extensive mountain-building events (or orogenies) occurred where the continents collided with one another, and the newly created high mountain ranges strongly influenced local and regional terrestrial climates.
East-west atmospheric flow in the temperate and higher latitudes was disrupted by two high mountain chains—one in the tropics oriented east-west and one running north-south—that diverted warm marine air into higher latitudes…
These developments may have contributed to the series of extinction events that took place...
Wegener’s outmoded concept of continental drift [as in slooowly]…simply stated that Earth’s continents were once joined together into the supercontinent Pangea that lasted for most of geologic time. [Instead] Plate tectonics states that Earth’s outer shell, or lithosphere, consists of large rigid plates that move apart at oceanic ridges, come together at subduction zones, or slip past one another along fault lines. The pattern of seafloor spreading indicates that Pangea did not break apart all at once but rather fragmented in distinct stages. Plate tectonics also postulates that the continents joined with one another and broke apart several times in Earth’s geologic history.
How are those dates established? With scientifically demonstrable evidence? So far the only “scientific” methodology presented has been alignment with a priori religious denial of a Creator God.

The Younger Dryas is one of the most well-known examples of abrupt change.
About 14,500 years ago, Earth’s climate began to shift from a cold glacial world to a warmer interglacial state. Partway through this transition, temperatures in the Northern Hemisphere suddenly returned to near-glacial conditions. This near-glacial period is called the Younger Dryas, named after a flower (Dryas octopetala) that grows in cold conditions and that became common in Europe during this time. The end of the Younger Dryas…was particularly abrupt. In Greenland, temperatures rose 10°C (18°F) in a decade (Alley 2000).
Around 15,000 years ago, the Earth started warming abruptly…A climatic optimum known as the “Bölling-Allerød” was reached shortly thereafter, around 14,700 before present. However, starting at about 12,800 BP, the Earth returned very quickly into near glacial conditions (i.e. cold, dry and windy), and stayed there for about 1,200 years: this is known as the Younger Dryas (YD)…
The most spectacular aspect of the YD is that it ended extremely abruptly (around 11,600 years ago)…the annual-mean temperature increased by as much as 10°C in 10 years.
One explanation is the one involving a thermohaline [warm salt water] circulation (THC) shutdown,
triggered by a catastrophic discharge of freshwater from Lake Agassiz.
Figure 2: (Left) The outline of Lake Agassiz just before the catastrophic flood. At that time its outlet was to the south into the Mississippi drainage. (Right) The outline after the opening of the eastward outlet. A volume of 9500 cubic kilometers of water was suddenly released to the northern Atlantic through the St. Lawrence Valley (Leverington et al. 2000). (Source: Broecker, 2003)
The consequence is a rapid reduction in northward ocean heat transports, leading to an abrupt cooling over Northern Europe and North America…
An alternate explanation (Clement et al., 2001) invokes the abrupt cessation in the El Nino -Southern Oscillation in response to changes in the orbital parameters of the Earth, although how such a change would impact regions away from the Tropics remains to be explained.
The respective merits of both hypotheses have been laid out by Broecker (2003). The issue is far from being settled, and actively researched at Lamont and elsewhere.
Now that is a scientifically cautious consideration that can be trusted. Unlike the definitive declarations by evolutionists. But I digress. Continuing with this source:
it is clear that the YD was a very strong event, yet it is also apparent that it was only the most recent of a series of large and abrupt climate swings that occurred repeatedly in the last ice age, and were recorded in many places around the globe, as attested by the number of red dots on the picture.
Under the rule of Sargon of Akkad, the first empire was established between about 4300 and 4200 calendar years before present (B.P). on the broad, flat alluvial plain between the Tigris and Euphrates Rivers (Weiss et al., 1993)…After about a hundred years of prosperity, however, the Akkadian empire collapsed abruptly at 4170 ± 150 calendar yr B.P. (Weiss et al., 1993; Postgate, 1992). Archaeological evidence documents widespread abandonment of the agricultural plains of northern Mesopotamia (Weiss et al., 1993) and dramatic influxes of refugees into southern Mesopotamia, where populations swelled (Weiss et al., 1993, Weiss, 2000). A 180-km-long wall, the “Repeller of the Amorites,” was built across central Mesopotamia to stem nomadic incursions to the south. Resettlement of the northern plains by smaller, sedentary populations occurred near 3900 calendar yr B.P. , about 300 years after the collapse. The stratigraphic level representing the collapse at Tell Leilan, northeast Syria, is overlain by a meter-thick accumulation of wind-blown fine sediments, suggesting a sudden shift to more arid conditions. Social collapse evidently occurred despite archaeological evidence that the Akkadians had implemented grain storage and water regulation technologies to buffer themselves against the large interannual variations in rainfall that characterize this region (Weiss et al., 1993).
It has been recently proposed (Cullen et al. 2000) that the demise of this complex civilization is due to a prolonged period of drought starting at 4025 ±150 years)…
The onset of sudden aridification in Mesopotamia near 4100 calendar yr B.P. coincided with a widespread cooling in the North Atlantic (Bond et al., 1997; deMenocal et al., 2000). During this event…Atlantic subpolar and subtropical surface waters cooled by 1° to 2°C…
The example of such a “mega-drought” and its dire consequences is particularly revealing of the vulnerability of complex societies to abrupt changes in our current climate, often believed to be much more stable than that of the “glacial world”…the last 11,000 years have been rather uneventful…in terms of temperature changes in Greenland. However, we see here that this did not preclude marked, regional changes in precipitation spanning entire…centuries in this case.
To further confirm the modern relevance of such abrupt climate change, we present below a map of the estimated extent of the Akkadian empire:
A quick comparison to a map of the modern Middle East, reveals that were such a megadrought to occur today over former Mesopotamia, which is now a region of exquisite geopolitical sensitivity, it would still have profound human consequences on the region. Judging by the history of the last 3 years, it would also have global strategic consequences.
Tragic consequences from ignoring reality does not just apply to climate change, signs of cancer, or world war.
The reality of the dates assigned to fossils is that they are based on a religion that rejects a Creator. Nothing more.
Anyone who accepts evolution rejects the Infinite Singularity who not only gives, but sustains life indefinitely. Doesn’t this decision deserve at least as much investigation as one would give before investing one’s life savings with an unknown telephone solicitor?
