Neanderthals were a species of archaic humans that inhabited Europe and parts of Asia between 600,000-40,000 years ago. They had shorter limbs than Homo sapiens but a more robust build adapted for cold climates. Dating methods like thermoluminescence, radiocarbon, and mass spectrometry on Neanderthal remains from sites like Saint-Césaire, Tabun, and Qafzeh indicate Neanderthals coexisted with early modern humans between 34,000-33,800 years ago, suggesting interaction was possible. While DNA and fossil evidence show Neanderthals were a separate species, it remains unclear if they directly interacted with or were replaced by H

William Golding imagined a prehistoric encounter between Neanderthals and our ancestors, Homo sapiens. In 1955, when he wrote the novel describing a preliterate society gradually exterminated by a more modern civilization, our understanding of this Stone Age encounter was sketchy. Scientists could not even say whether Homo sapiens sapiens had lived at the same time as Neanderthals, or instead were descended from them. But in the last 10 years, a much more complete picture has emerged of what happened--40,000 years ago--when the last two branches of the human family tree met, and one prevailed.
Neanderthals were not as primitive as they are often portrayed in popular culture. They were humans like us, and their brains were at least as big as ours. They were larger and stronger, and were successful hunters of big and small game. They probably even had language, which is generally thought to have arisen between 300,000 and 400,000 years ago. They were, in any case, anatomically capable of speech. Their stocky bodies are thought to have made them well adapted to the northern latitudes and glacial climates of Europe, where they lived for at least 300,000 years--far longer than we have.

FOR 27 YEARS, CHRIS STRINGER AND
Milford Wolpoff have been at odds about
where and how our species was born.
Stringer, a paleoanthropologist at the Nat-
ural History Museum in London, held that
modern humans came out of Africa, spread
around the world, and replaced, rather than
mated with, the archaic humans they met.
But Wolpoff, of the University of Michigan,
Ann Arbor, argued that a single, worldwide
species of human, including archaic forms
outside of Africa, met, mingled and had
offspring, and so produced Homo sapiens.
The battle has been long and
bitter: When reviewing a man-
uscript in the 1980s, Wolpoff
scribbled “Stringer’s desper-
ate argument” under a chart;
in a 1996 book, Stringer wrote
that “attention to inconvenient
details has never been part of
the Wolpoff style.” At one tense
meeting, the pair presented
opposing views in rival sessions
on the same day—and Wolpoff
didn’t invite Stringer to the
meeting’s press conference. “It
was diff icult for a long time,”
recalls Stringer.
Then, in the past year, geneticists an-
nounced the nearly complete nuclear
genomes of two different archaic humans:
Neandertals, and their enigmatic eastern
cousins from southern Siberia. These data
provide a much higher resolution view of
our past, much as a new telescope allows
astronomers to see farther back in time
in the universe. When compared with the
genomes of living people, the ancient
genomes allow anthropologists to thor-
oughly test the competing models of human
origins for the fi rst time.
The DNA data suggest not one but
at least two instances of interbreeding
between archaic and modern humans, rais-
ing the question of whether H. sapiens at that
point was a distinct species (see sidebar,
p. 394). And so they appear to refute the com-
plete replacement aspect of the Out of Africa
model. “[Modern humans] are certainly com-
ing out of Africa, but we’re fi nding evidence
of low levels of admixture wherever you
look,” says evolutionary geneticist Michael
Hammer of the University of Arizona in Tuc-
son. Stringer admits: “The story has undoubt-
edly got a whole lot more complicated.”
But the genomic data don’t prove the
classic multiregionalism model correct
either. They suggest only a small amount
of interbreeding, presumably at the margins
where invading moderns met archaic groups
that were the worldwide descendants of
H. erectus, the human ancestor that left
Africa 1.8 million years ago. “I have lately
taken to talking about the best model as
replacement with hybridization, … [or]
‘leaky replacement,’ ” says paleogeneticist
Svante Pääbo of ...
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

5. Acheulian Tradition- the name given to an archaeological
industry of stone tool manufacture associated with
prehistoric hominins during the Lower Palaeolithic era
across Africa and much of West Asia and Europe.
Acheulean tools are typically found with Homo erectus
remains.
Archaeological Industry- the name given to a consistent
range of assemblages connected with a single product,
such as the Langdale axe industry. Where the assemblages
contain evidence of a variety of items and behaviours, the
more correct term is "archaeological culture".
6. Aurignacian- the name of a culture of the Upper Palaeolithic located
in Europe and southwest Asia. It dates to between 32,000 and 26,000
BC. The name originates from the type site of Aurignac in the Haute
Garonne area of France. The Aurignacian culture is considered by
some archaeologists to have co-existed with the Périgordian culture
of tool making.
Mousterian- name given by archaeologists to a style of
predominantly flint tools (or industry) associated primarily with
Homo neanderthalensis and dating to the Middle Paleolithic.
Mousterian technology may have been evolutionarily significant
because it may have partially replaced the function of the incisor
teeth.
Chatelperronian- the earliest industry of the Upper Palaeolithic in
central and south western France, extending also into Northern
Spain. It derives its name from the site of la Grotte des Fées, in
Châtelperron, Allier, France.
7. Thermoluminescence dating- is the determination by
means of measuring the accumulated radiation dose of the
time elapsed since material containing crystalline minerals
was either heated (lava, ceramics) or exposed to sunlight
(sediments). As the material is heated during
measurements, a weak light signal, the
thermoluminescence, proportional to the radiation dose is
produced.
8. Excavation of a collapsed rock shelter
near Saint-Césaire resulted in
Mousterian, Châtelperronian, and
Aurignacian lithic remains. These
findings were divided into 17 different
levels
Mousterian of Acheulian- Layers 16-13
Denticulate Mousterian- Layers 12-10
Châtelperronian- Layers 9-8
Body remains in Saint-Césaire yielded a skull resembling that of a
Neanderthal skull with modern human features, however, these remains did
not contain enough collagen to attempt a carbon dating procedure
These levels yielded 20 flints capable of being dated through the use of
thermoluminescence
9. Neanderthal remains found at Saint-
Césaire suggest that Neanderthal
could have lived alongside
occupants of similar radiocarbon-
dated Aurignacian sites, such
L’Abri Pataud (34,250+-1,800 years
BP) or Le Flageolet (33,800+-1800
years BP). Both French sites were
occupied by modern humans,
placing the Saint-Césaire
Neanderthal at the same time period
as Homo sapiens.
According to these findings the
theory that Neanderthal’s
disappearance is a result of
evolution into modern man is not a
logical possibility
10. In 1997 mitochondrial DNA of a
Neanderthal was found and
sequenced. The analysis shows it
is outside of that of modern
humans but shares a common
ancestor with humans around
500,000 years ago. When
compared to modern human it is
seen that Neanderthals donated
little or no mitochondrial DNA.
This evidence provides a very
strong argument to debunk the
myth that we are descendent of
Neanderthals.
11. Excavation of the cave of the Grotte des
Fées at Châtelperron contained a sequence
of at least eight archeological levels,
extending over a total depth of at least 2.5
m and containing at least five clearly
defined levels of Châtelperronian
occupation (levels B1-B5). These were
underlain by at least 1.5 m of late
Mousterian deposits (layers C1-C3),
containing a typical Mousterian of
Acheulian tradition industry
• Found within these Châtelperronian levels were Aurignacian tool forms
(level B4) clearly sandwiched between Châtelperronian activity (levels B5 and
B1-3).
12. In support of stratification techniques radiocarbon dating
was performed. These radiocarbon dating tests show, the
Aurignacian tool forms were in fact older than the
Châtelperronian artifacts found in levels B1-3 and
younger than those found in level B5
These two test techniques proved that Neanderthals and
modern humans coexisted in the same environment and
possibly even interacted with each other
13. In a 1993 study, scientists used
mass spectroscopy to date
Neanderthal and early hominid
remains from three burial sites
in the Levant, Tabum, Qafzeh,
and Skhul
The mass spectroscopy research
indicated that the homo sapiens
of the Qafzeh cave may be older
than the Kebara Neanderthal
and these same homo sapiens
may have lived at the same time
as the Neanderthals whose
remains were found at level C
of the Tabun site.
14. The results of this study helped to show the potential for
mass spectrometric U-series dating of small samples since
the results of these dates correspond to the early uptake
ESR estimated ages. Also this study provided evidence for
more ancient chronologies of these three sites. And finally
this study helped provide more reason to belief that homo
sapiens and Neanderthals probably lived at the same time
rather than homo sapiens being the descendants of
Neanderthals
15. In conclusion, the experiments conducted using thermoluminescence
dating, analysis of Neanderthal DNA base pairs, radiocarbon dating,
and mass spectrometric U-series dating all resulted in the dating of
various Neanderthal remains. However, the experiments did not
provide conclusive evidence as to whether or not Homo sapiens and
Neanderthal man did in fact interact. While the dates retrieved from
the various methods suggest that Neanderthal man and Homo sapiens
did coexist, there is no conclusive evidence that both societies
interacted with eachother. What the experiments did conclude was
the possibility of Neanderthal and Homo sapiens coexisted, since
dating of the two remains coincide within the same time period.
With advances in dating methods, we can only hope that new
archeological sites will surface containing remains of both
Neanderthal man and Homo sapiens that provide conclusive
evidence between the interaction of the two beings.
