Consider the long legs of wading birds such as herons and egrets- bird.pdfchennaiventure
Consider the long legs of wading birds such as herons and egrets, birds that are common around
rivers and marshes, How could such a bind evolve such long legs? Read the following scenarios
and discuss each with your partner. Use the questions at the bottom to help in this discussion.
Assume that the species ancestral to these birds had short legs, and could only wade into very
shallow water along the shoreline, eating snails and small fish. SCENARIO A. A change in the
environment increased competition between the birds, and resulied in a SCENNARIO A. A
change in the environment increased competition between the birds, and resulied in deeper water
the food supply in the shallow waters, This created a need for the short-legged birds to wade into
over by the litle warvive, which forced them to stretch their legs, because they didn't want to get
knocked over by the little waves. This stretching caused their legs to get a little longer. When
these birds produced chicks, the baby birds grew up with the slightly longer legs inherited from
their parents. These offspring birds needed to wade out even further, so they stretched their legs
even more, and made them a little bit longer yet. And their chicks grew up with even longer legs
inherited from their parents. And so on... Eventually, after many generations of this, the legs of
these birds were so much longer than the ancestral birds that the new birds could be described as
a new species. SCENARIO B. Within the species of ancestral short-legged shore birds, there is a
range of leg lengths, from a little bit shorter to a little bit longer than the average leg length, and
these leg lengths tended to run in families (i.c. leg length was hereditary). A change in the
environment increased competition between the birds, depleting the food supply in the shallow
waters. The birds with slightly longer legs, of course, could wade out a little farther. As a result,
they got more food, lived a little longer, and therefore produced more chicks. Those with the
shorter legs would tend to starve to death. Since the tendency for leg length was already
inheritable, the surviving "long-leggers" tended to have more long-legged chicks, which likewise
tended to get more food and produce more chicks. And so on... Eventually, after many
generations of this, the average leg length of these birds was so much longer than in the ancestral
birds (along with other connected changes) that the new birds could be described as a new
species. DISCUSSION: 1. Which scenario sounds like an explanation Darwin might give? B
Why? - Scenario B sounds like ouhat Darwin would explain becavis 2. Which scenano sounds
like an explanation Lamarck might give? A Why? 3. What are the specific clues which most
clearly distinguish a Darwinian explanation from a Lamarckian explanation 4. Which
explanation is most likely correct (in terms of the relative evidence between Darwin's hypothesis
and Lamarck's hypothesis)? 5. Write a similar pair of scenarios.

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.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
