Describe it :
Large spiders covered with hairs -
known as tarantulas - are spread throughout the world except Antarctica.
These
spiders belong to the wolf spider family, and are known
in
English as "Tarantulas"
(Tarantulas) is named after the Italian city of "Taranto",
from which the name of these spiders is derived.

Imaginative weave and mysterious questions:
The name tarantula spiders has been
linked to many frightening stories - and sometimes fictional ones - that gave
them a horrific shape in human ears.
When
the peasants discovered them in the city of Taranto, they believed that they
had a poisonous and deadly bite,
Which
eventually led them to devise an unconventional antidote to recover from the
madness that results from her bite.
This
antidote was a dance known as "Tarantella," but it appears that these
bites were caused by other creatures, as the tarantula found in this area had
no significant danger.
These spiders rarely leave their
places, as the female always remains close to her young, while her adult male
only travels to search for his partner, which raises the question: How did
these spiders spread in this way globally?
Recently,
an international team of scientists searched for the ancestors of tarantula
spiders, which strike more than 100 million years ago, and the study was
published in the journal PeerJ on April 6/ This April.

Rare fossils:
According to the report published by
Live Science, tarantula fossils are extremely rare, as there are only two
well-preserved fossils One is in Mexico - which dates back to about 16 million
years - and the other is in Myanmar, which dates back to 100 million years.
Due
to the scarcity of tarantula spider fossils, researchers have collected any
fossil data for the suborder Mygalomorphs, which includes a large group of
large spiders that live on Earth, including tarantulas, The fossil record of
this group is very rich.
Scientists
also relied on databases of RNA molecules that encode (produce) protein to
build the family tree of these spiders.
Once
the tarantula family tree - which included 29 species of tarantula and 18 other
species of large, rattel-shaped spiders - was determined, scientists drew a
chronological map of that spider tree, relying on The fossils in their hands, which ultimately
enabled them to know the time and place where these spiders appeared and spread
to different regions of the world.

Chronology and spatiality:
According to the press release
published by Carnegie Mellon University in response to the study,
Scientists
have discovered that tarantulas first appeared 120 million years ago - that is,
during the Cretaceous period - in what is currently known as the Americas,
which were part of the giant continent of Gondwana at that time.
It is
possible that the ancestors of ancient tarantulas spread across the land mass
of the Americas until they reached Africa, Australia, and India,
The
team found that the ancestors of tarantulas that appeared in Africa date back
to about 112 million to 108 million years ago, and the ancestors of tarantulas
appeared in India 108 million years ago.
With
the separation of the continent of Gondwana, India separated from Madagascar 95
million to 84 million years ago and drifted to attach to the continent of Asia
approximately 58 million to 35 million years ago, bringing these spiders with
them to the continent of Asia.

Different breeds:
However, the ancestors of the tarantula
that spread in India were distinguished into two breeds with a different
lifestyle, as the first breed inhabited trees, while the other breed preferred
to live in burrows.
Both
breeds spread in Asia, but the first to spread was the breed that hides in
burrows,
While
the tree lineage - also known as the Earth Tigers - followed it 20 million
years later.
This second spread by the tree strain indicates that spiders were highly adaptable to their new environment, which contradicts what some studies had previously thought.

Discovering two new species of spiders A warning of the danger of their extinction:
Scientists have discovered two new
species of tarantula spiders on the slopes of the Andes Mountains in South
America, and both appear to be threatened with extinction.
"Newsweek"
magazine said that researchers from the University of San Francisco de Quito in
Ecuador documented spiders found in trees in the wilderness of the west of the
country.
According
to the study, which was published in the scientific journal ZooKeys, a new type
of tarantula was identified in late February of this year, at the foothills of
the Cordillera Occidental Mountains,
It is
one of the two main mountain ranges in the Andes.

Newsweek reported:
"Although
this new species, called Psalmopoeus chronoarachne, has recently been
discovered,
Available
evidence indicates that it is seriously threatened with extinction due to human
activities in the region, such as mining and agriculture".
The
scientific name of the species is based on the Greek words for "time"
and "spider".

"It was given this name because

Tarantulas
are a variety of large spiders that are often hairy, found mainly in warm
regions around the world.
To
date, more than a thousand species of tarantulas have been identified.
