Exactly. Bipedal hominids have been around 4.4 million

I'm trying to understand it. Is it basically saying that 100,000 - 200,000 years ago, 90% of the species on the earth were eliminated to the extent that the "clock" on these DNA barcodes reset?

It is a published peer reviewed study, but you are correct this doesn't say what everyone here wants/claims it to say.
I wasn't calling the study clickbait. I'm calling the article clickbait.

The study actually says that most species share mitochondrial DNA with a common ancestor within the last "several hundred thousand years" preceding population increases.
Not at all the same thing as "90 Percent Of Earth’s Animals Appeared"
In other words, when they got off the Ark, bro.

I'd view it that 100-200k years ago there was a niche created that allowed the species we see today to blossom while others were selected out.

The people that made us made the animals as well.

Not replying to you...
I'd like to see their data before reading too much into this, but for the last few days at work we have been wondering how many different species and the population distribution to see where they got the 90% figure.
It was said that the big clue here is that they used "animals" and not total species to include microbes. The microbe numbers to me would have shown more impact.

Please change the OP title to: Massive Amount of Ignorance by Nicole Arce Says 90 Percent of Animals Appeared at the Same Time
I love most millennials but every group has its ignorant bitches. Arce may have some smarts but DNA certainly isn't one of them.
Best of the comments for the article:

This article's headline is hilariously, irresponsibly inaccurate. The authors of this study don't conclude anything resembling the "90% of species appeared within the past 200,000 years" nonsense that this article conjures from thin air. It is effectively concluding that most animals have had a "mitochondrial Eve" in the past 200,000 years (that is, an ancestor from whom all modern individuals of that **already extant** species have inherited their mitochondrial genomes). Don't get your science news from unreliable news sources, folks.

Yeah it was like the same week if I remember correctly.

As in, they were made on the same days? Hmmmm, who da thunk

That figure has been pushed back to 6.7 million years with the discovery of Sahelanthropus tchadensis, or "Toumai" in Chad 10 years ago.

Wait.... you mean after the last extinction that most things that survived have a common ancestor?
No.
Way.

Oh, I think you're right. She usually writes sensible articles but, man, she goes off the rails sometimes. This is definitely one of those "your brain on drugs" examples.

all these test and time wasted.. just read the first chapter of the Bible. The answer has literally been sitting there the whole time
