Just Grok it 2

Fight to end fake news, propaganda and grifters.

By simply Grok it when you are using X-Twitter.

When you do, you will get a small book review. A real piece of scientific quality explaination that I am sure is studied and read by every single MAGA voter.

Here is the start and the gist:

1. Yes, the core claim in this meme is true, based on peer-reviewed scientific research into ancient human footprints discovered in Australia. Here’s a breakdown of the facts:The Discovery

The full response is at the bottom, it is worth a read. Fascinating world we live in. Incredible what achievements humanity can achieve and some we have apparently been able to do for 20.000 years.

So, if you like everyone else that is not profiting from spreading fake news, are ready to make a change?

Just Grok it.

Because facts matter.

Then take the time to read a small book.

I ask, is there not a better way to fact check. First a concise answer. Then the long one that those that just have to know can read?

When really when you think about it, it was a yes or no question.

Now for the nerds, truthseekers, justice seekers and all those that are tired of fake news and can’t stop the urge to know it all, here is the full comment by Grok to a simply question on a great meme.

1. Yes, the core claim in this meme is true, based on peer-reviewed scientific research into ancient human footprints discovered in Australia. Here’s a breakdown of the facts:The Discovery

• Location: Willandra Lakes region, Mungo National Park, New South Wales, Australia (not “New South Wales” in the sense of the modern state capital area, but the broader region).
• Age: The footprints date to approximately 19,000–23,000 years ago (Late Pleistocene), confirmed via optically stimulated luminescence (OSL) dating of the surrounding sediment.
• Study: Published in Journal of Human Evolution (2013) and PLoS ONE (2021), led by researchers including Steve Webb (archeologist) and Matthew Cupper (geochronologist).

The Sprinting Claim

• One set of tracks (labeled T1) shows 109 consecutive human footprints made by multiple individuals, including a tall adult male (~1.8–1.9 m / 6 ft) running barefoot across wet clay.
• Stride length: Up to 2.7 meters (exceptionally long for a human).
• Speed estimate: Using biomechanical models (based on stride length, leg length, and footprint spacing), researchers calculated:
• ~37 km/h (23 mph) in soft, wet clay.
• This is comparable to elite modern sprinters on a firm track (e.g., Usain Bolt averaged ~37.6 km/h over 100m in his 9.58s world record, peaking near 44 km/h).
• The runner was likely chasing prey or fleeing — the tracks show high speed sustained over at least 20–30 meters.

Key Evidence from the Studies

Measurement

Value

Max stride length

2.7 m

Estimated leg length

~0.95 m

Speed (wet clay)

36.5 ± 1.9 km/h

Modern Olympic 100m avg

~37–38 km/h

Source: Webb et al., PLoS ONE (2021) — “The speed of a human: Running footprints from the Pleistocene of Australia”

Why It’s Impressive

• The surface was soft, wet clay — much harder to run on than a modern polyurethane track.
• The runner was barefoot, with no shoes or spikes.
• Despite this, the speed matches or nearly matches modern elite sprinters under ideal conditions.

The Meme’s Image

• Left: A modern reconstruction of an Australian Aboriginal hunter (artist’s depiction, not a photo).
• Right: Usain Bolt at the 2016 Rio Olympics.
• The comparison is symbolic but accurate in highlighting the speed parity.

Verdict: TRUE

20,000 years ago, a barefoot hunter in Australia sprinted at ~37 km/h — Olympic-level speed — on wet clay.

This is one of the earliest direct evidences of high-speed human locomotion preserved in the fossil record.Sources:

The meme is scientifically accurate, not exaggerated.
