Homo naledi Turns Out to Be Much Younger Than Expected

This has been an interesting week for the evolution of two assumed human ancestors.

First, the journal Science suggested that Australopithecus sediba should be tossed out of the human family tree. Then, National Geographic acknowledged that Homo naledi is “only” 200,000 – 300,000 years old, making it far too young to be a direct human ancestor.

Both discoveries were known to be very controversial.

In 2010 Lee Berger and his team discovered Australopithecus sediba that was once touted as a human ancestor but was later practically tossed aside by some other anthropologists.

Then, in 2015 Professor Berger and colleagues published a paper on what they claimed to be a new human species. Found in a cave in South Africa, their discovery consisted of 1,500 pieces of teeth and bones that were not dated, and some experts thought they might be too young to fit into our family tree.

One of the estimates put their age at 912,000 years BP (before present).

Now, in an interview published in National geographic, Berger suggested that H. naledi might be a lot younger.

For evolutionists, the curved ape-like fingers, small skull and other primitive features of H. naledi are an enigma. They believe that modern H. sapiens appeared some 200, 000 years ago, leaving practically no time for evolution.

Chris Stringer of the Natural History Museum in London thinks that H. naledi might be “a relic species, retaining many primitive traits from a much earlier time.”

Prof. Berger has likened it to the Coelacanth (Latimeria chalumnae), the living fossil that was supposedly able to retain primitive features for 400 million years.

Others have compared it to the hobbit or H. floriensis that has been the source of heated debate since its discovery in 2003.

And least one thing is sure: there’s no end in sight for updates to our assumed family trees, and artists will hardly have to fear for their jobs until the day comes when Darwinian evolution will be tossed out as pseudoscience.

Holocaust Remembrance Day: Time to Remember What Science Gone Wrong Can Do and What Some Heroic Dissenters Did

Just two days after Bill Nye, Neil deGrasse Tyson and many others praised the wonders of consensus science, it’s time for Holocaust Remembrance Day.

It is a stark reminder of how far science can go astray. Just over 70 years ago, eugenics was seen as a valid field of research, and Josef Mengele was conducting scientific experiments on Jews at Auschwitz.

Historians will tell us that the Holocaust was inspired by Darwinian evolution. German Nazis sought to help natural selection to get rid of the “unfit”.

Fortunately, among all the destruction, Oskar Schindler and other brave dissenters saved the lives of hundreds of Jews.

Sir Nicholas Winton shipped 669 Jewish children to Great Britain.

Irena Sendler, a Polish social worker, teamed with 20 others and smuggled 2,500 children out of the Warsaw Ghetto, some in ambulances and trams between October 1940 and April 1943 and placed them in Catholic homes.

Under the pretext of inspecting the ghetto's sanitary conditions during a typhoid outbreak, Mrs Sendler and her assistants went inside in search of children who could be smuggled out and given a chance of survival by living as Catholics,” the Daily Mail reported in 2008, when she died at age 98.

She risked her life in the brave operation and despite being caught in 1943 and tortured, she refused to betray any of her helpers – and outlived those who tried to stop her.

Does Mother Earth Day Inspire the March for Science?

Mother Earth has become a cultural icon.




Joel Kontinen

It used to be known as Earth Day. The United Nations has gone a step further and re-named it The International Mother Earth Day.

The green ideology behind this move could hardly have been more obvious.

Some would even say that the mushroom is our brother.

Some others want to give apes and rivers the same rights we have.

The post-Christian world wants its share of holy days, such as Darwin Day and Earth Day.

It is probably no coincidence that the March for Science takes place on 22nd April or (Mother) Earth Day.

To mark the day, we have a celebrity scientist (Neil deGrasse Tyson) warning of the dangers “science denial”.

If this sounds like the newspeak introduced by George Orwell, the most likely explanation is that it indeed is.

By this he means being sceptical of consensus science, i.e. Darwinian evolution and human-induced climate change.

It seems that most of the marchers are leaning left politically. Some of them are probably worried about the war on science, which, as we know, is another illustration of Orwellian newspeak.

We should not forget that while we have a mandate to care for Earth, we should certainly not worship it – that would be idolatry.

LHS 1140b: Newly Discovered Super-Earth Might Not Be a Good Place for Life

Joel Kontinen

The naturalistic worldview can’t tolerate the possibility that we are unique or that our planet might be very special. It requires a universe that is teeming with alien life.

After all, if life evolved on Earth, it should have evolved elsewhere as well, the naturalist thinks.

Thus, from time to time we are bombarded with the news of the discovery of an Earth-like exoplanet that might harbour life.

The latest candidate is LHS 1140b. Described as a “rocky, temperate super-Earth,” it orbits a red dwarf every 25 days, some 40 light years from us.

Red dwarfs tend to be anything but calm, throwing our flares that would soon snuff out all emerging life, but astronomers assume that the star LHS 1140 is unusually calm.

They hope it has liquid water. However, we can’t be sure of that. It might well be wishful thinking.

NASA and other space agencies have made so many false alarms in the past, so it’s best to remain a bit sceptical.

New Scientist discusses five of the best candidates for alien life. None of them are very convincing.

The Trappist system turned out to be a big disappointment after the initial excitement died off, and the other recently discovered “Earth-like” planets – Proxima b, Kepler 186f and GJ 132b – have not fared well, either.

What we know is that Earth’s twin is still missing and will probably remain so, as life only comes from life. It cannot be produced by Darwinian mechanisms.

It has to be created. In the beginning God createdis still the best explanation for why there is life anywhere in the universe.

Amber Discloses “99-Million-Year-Old” Symbiosis Between Beetles and Termites

Symbiosis is not a modern invention. A paper published in the journal Current Biology re-writes the known history of symbiosis between beetles and termites:

Tracking the relationship between ancient termites and symbionts like rove beetles has proved challenging; this new evidence indicates that rove beetles partnered with termites 80 million years sooner than previously thought,” Live Science reports.

The previous record-holding termitophiles were “19 million years” old.

Found in a mine in Burma (Myanmar), Cretotrichopsenius burmiticus are only 0.7 millimetres (0.03 inches) long and look like today’s rove beetles that live in symbiosis with termites.

This shows that there’s hardly anything new under the sun. Most insects trapped in amber look practically the same as today’s animals.

Beetles are living fossils that haven’t changed since the heydays of the dinosaurs.

New discoveries are pushing back the dates when animals lived. If this trend continues, we will sooner or later have all kinds of organisms living at the same time and Darwinian evolution will be in big trouble.

Live Science Tries to Explain the Ten Plagues of Egypt "Scientifically", and Fails



The Plague of Flies, c. 1896–1902, by James Jacques Joseph Tissot. Public Domain.




Joel Kontinen

Easter is the season when sceptics try to cast doubt on the reliability of the Bible.

One of their strategies is to explain away the miraculous in the Bible, but often their brave new theories lack substance.

Jesus’ death is their favourite, but they also have naturalistic versions of other events, such as Saint Paul’s conversion, which according to their view was caused by a meteor.

This time Live Science attempts to give a scientific explanation for each of the 10 plagues described in the Old Testament book of Exodus:

The 1st plague, blood, was probably caused by a red algae bloom colouring the Nile red.

The 2nd plague, frogs, is not so special as frogs tend to drop from the sky every now and then.

The 3rd plague, lice, might be associated with the bubonic plague.

The 4th plague, flies, might have been any wild animal, including some bigger ones, such as snakes, lions or bears.

The 5th plague, livestock disease, could have been caused by rinderpest.

The 6th plague, boils, could have been smallpox.

The 7th plague, hail, might have been caused by an eruption on the Greek island of Santorini.

The 8th plague, locusts, might be a consequence of the Santorini eruption.

However, according to some estimates the volcano on Santorini might have erupted 300 years before Moses' time.

The 9th plague, darkness, was could have been caused by a solar eclipse (which, however, never last for three days) or by ashes from the Santorini eruption.

The 10th plague, death of the firstborn, might have been caused by eating grain infected by the poisonous algae bloom.

But why would this only kill the firstborn, some of whom were still babies, and no one else?

For Live Science, the answer is not even blowin’ in the wind.

In 2010 the National Geographic Channel aired a programme that featured rather similar explanations.

It is probably needless to say that their solutions were not at all credible.

Easter: The Resurrected Christ Lives in Spite of Conspiracy Theories and Fake News

Joel Kontinen

Easter seems to be a difficult time for unbelievers. While Christians celebrate the passion of Jesus Christ that brings salvation for all who believe in Him, atheists and other sceptics try to explain why they are unwilling to accept the testimony of hundreds of reliable witnesses who saw the Lord Jesus alive after the resurrection.

They have invented several conspiracy theories as an excuse for not believing a historical fact.

The Apostle Paul says that Jesus is the Last Adam.

The first Adam brought death into the world by eating from a tree.

The Last Adam overcame death by dying on a tree.

Just in time for Easter, Graham Lawton asks whether atheism is a religion. While he would not agree with my conclusion, atheism requires faith. It relies on a speculative and ever-changing narrative of how we got here.

In contrast, the Bible is based on true history. Jesus’ empty tomb confirms that He is truly risen.

Have a blessed Easter time!
