Your Questions About How To Discover New Species

Lisa asks…

What are the 10 most recently discovered new species?

New Niche Finder answers:

Impossible to say. If I did find the ten most recent, a few others might have been discovered in the meantime.

Interestingly, 16,969 species were discovered in 2006 (article in source), which is roughly 50 per day (according to the article). Haven’t actually read it, but I do know that we find more new species than most people would expect.

In terms of animals, I can’t say for sure.

Ruth asks…

what do u call some1 who discovers new species of fish?

THANKS!

New Niche Finder answers:

The studies of taxonomy and phylogeny are where new species would be describe. People that study those fields are not always those who actually find the species, but people who have a background in those fields are needed in order to distinguish a species from another. That’s about the closest you can get to describing a person who would discover a species, but there is no name for someone that discovers a species, but those who actually name them are taxonomists generally.

Nancy asks…

Have you seen the newly discover species……♥?

Of Rat and Tiny pygmy possum? I wonder how many new species have been discovered in our lifetime.

That is one huge Rat!
I asked this in honor of Wally’s (earlier) Rat Question…♥

New Niche Finder answers:

I think I saw this species last night at walmart, in the towel isle.

DNA links humans, mystery species

Neanderthal ‘sibling’ once roamed Africa

The human family tree just got another — mysterious — branch, an African “sister species” to the heavy-browed Neanderthals who once roamed Europe.

While no fossilized bones have been found from these enigmatic people, they did leave a calling card in present-day Africans: snippets of foreign DNA.

There’s only way one that genetic material could have made it into modern human populations.

“Geneticists like euphemisms, but we’re talking about sex,” said Joshua Akey of the University of Washington in Seattle, whose lab identified the foreign DNA in three groups of modern Africans.

These genetic leftovers do not resemble DNA from any modern-day humans. The foreign DNA also does not resemble Neanderthal DNA, which shows up in the DNA of some modern-day Europeans, Akey said. That means the newly identified DNA came from an unknown group.

“We’re calling this a Neanderthal sibling species in Africa,” Akey said. He added that the interbreeding likely occurred 20,000 to 50,000 years ago, long after some modern humans had walked out of Africa to colonize Asia and Europe, and around the same time Neanderthals were waning in Europe.

Akey said that present-day Europeans show no evidence of the foreign DNA, meaning the mystery people were likely confined to Africa.

The find offers more evidence that for thousands of years, modern-looking humans shared the Earth with evolutionary cousins who later died out. And when the groups met, they did what came naturally — they bred.

The once controversial idea that humans mated with other species is now widely accepted among scientists. In fact, hominid hanky-panky seems to have occurred wherever humans met others who looked kind of like them.

In 2010, researchers from the Max Planck Institute for Evolutionary Anthropology in Germany announced finding Neanderthal DNA in the genomes of modern Europeans.

Neanderthals — heavy-set people whose thick double brows, broad noses and flat faces set them apart from modern humans — disappeared around 25,000 to 30,000 years ago.

Another mysterious group of extinct people recently identified from a finger bone in Siberia — known as the Denisovans — also left some of their DNA in modern-day Pacific Islanders.

And while modern humans and the newly found “archaic” Africans might be classified as distinct species, they managed to produce viable offspring. Likewise, donkeys and horses, lions and tigers, and whales and dolphins can mate and make babies.

“They had to be similar enough in appearance to anatomically modern humans that reproduction would happen,” said Akey. But with no fossils in hand, it’s impossible to say what these people looked like. It’s also impossible to say whether the matings were consensual or forced.

But one thing is clear: This enigmatic group left their DNA all across Africa. The researchers found it in the forest-dwelling pygmies of central Africa and in two groups of hunter-gatherers on the other side of the continent — the Hadza and Sandawe people of Tanzania.

Starting a decade ago, a team led by Sarah Tishkoff of the University of Pennsylvania drew blood from five individuals in each of the three groups.

Using the latest genetic technology, Tishkoff spent $150,000 to read, or sequence, the DNA of these 15 people.

Besides finding evidence of the now-extinct species, the team discovered a huge range of genetic diversity among the three groups. The human genome contains about 3 billion letters, or base pairs, of DNA. Before this study, scientists had found that about 40 million of these letters vary across human populations.

But in the 15 Africans, Tishkoff found another 3 million genetic variants — a huge trove of human diversity. Among this stunning variety, Tishkoff says she has pinpointed some of the genes responsible for the short stature of the pygmies, who average less than 5 feet in height. She also found that immune-system genes, as well as genes for taste and smell, varied wildly among the three groups — confirming Africa as the seat of the most human diversity.

The research was reported Wednesday in the journal Cell.

“This is very cutting-edge population genetics work,” said geneticist Spencer Wells, a National Geographic explorer. “This ‘whole genome’ analysis the team performed is really revolutionizing our understanding of human history. It’s an exciting time to be in the field, but it’s difficult to interpret all the new data.”

Wells said the oldest modern human skull, found in Ethiopia, dates back 195,000 years. For more than 150,000 years, humans shared the planet with cousin species.

Despite all the amorous advances, only one group survived — us.

“As we were conquering the world, we also conquered similar human populations that were dying out,” Akey said.

Richard asks…

Advantages and Disadvantages of discovering a new species?

What is an advantage and disadvantage for a citizen, student, biology profession when a new spider specie is discovered which has the most advanced self-defense (building decoy spiders to scare off preys or attract preys to eat) or discovering new species in general?

The link to the article if you need more info about this specie:

New Niche Finder answers:

There are really no disadvantages in the discovery of a new species.
The person making the discovery has the choice of naming it.
I wasn’t able to open your link, so I don’t know what spider you are trying to find information for.
From your general description though, this sounds like the spider that makes a decoy spider in its web.
This is a misinformed information about a common spider called a trashline orb weaver that in this one instance, decorated its web in a fashion that resembles a spider. The spider is not a new species, nor would a spider have the brain capacity for such creative thought. In their natural instinct, these spiders decorate their web with debris that the spider can camouflage itself to in it effort to avoid predation.
It also attracts flying insects that the spider preys on.

Spiders are fascinating little critters, each with their own way to survive, and there are many spiders yet not discovered,(described in scientific lingo)
