Evolution of Bipedalism

 

This human evolution packet provides an extensive guide for students to learn about the evolution of bipedalism in early hominid ancestors, specifically Australopithecus Afarensis, from several different perspectives. The entire curriculum can be presented to students within a time period of one or two weeks, or it can be used to supplement current teachings about evolution. One of the most common questions hear from students is, “how do we know evolution is true?” Many students have difficulty understanding that homo sapiens descended from primitive hominids who once inhabited lush forest in Eastern Kenya. This curriculum brings together our current knowledge of human evolution, and places it into a context where students can see how and why we transitioned from aboral life to living permanently as bipedal individuals. Students will explore the anatomical changes that occurred over time to facilitate upright walking and develop an understanding of how humans developed the ability to walk on two feet while expending less energy. By exploring Newton's laws of motion and mechanics, students will grasp the concept of the emergence of bipedal locomotion.

The activity begins with an introduction to the general concept of bipedalism and six theories that explain the environmental pressures that led to its emergence. Students will identify homologous structures such as the pelvis, foramen magnum, feet, and spine, and compare them across modern humans, chimpanzees, and our ancestor Australopithecus Afarensis. This information will provide students with an understanding of the role each line of evidence plays in relation to common ancestry and the biological evolution of bipedalism.

Furthermore, the packet includes a Google Slides presentation with videos, questions, and information about the evolution of bipedalism and intelligence. As humans became bipedal, they were able to access higher calorie food, and tool use became more sophisticated, which led to the emergence of human intelligence. Students will explore the connection between bipedalism and the emergence of human intelligence, making bipedalism one of the most significant hallmarks of our evolutionary journey.

In addition, students will compare the male and female Homo sapien pelvis as well as the male and female chimpanzee pelvis. This comparison will provide students with a deeper understanding of the biological differences between males and females within the species and how these differences relate to bipedal locomotion. The exploration of sexual dimorphism in hominids highlights its importance in human evolution and how it has influenced our anatomy and physiology.

Overall, this packet offers an engaging and informative educational resource for students interested in anthropology, biology, and evolutionary science. Students will gain a deeper understanding of human evolution by examining the anatomical changes and environmental pressures that led to the development of bipedalism. The comparative anatomy of the male and female Homo sapien and chimpanzee pelvis will allow students to appreciate sexual dimorphism and its role in human evolution. This packet aligns with the NGSS Science Standards by providing students with an in-depth exploration of evolutionary biology, comparative anatomy, and the application of scientific concepts to understand human evolution.

The number of students learning English in American schools is getting bigger each year, but these students aren't doing as well as they should be on academic tests or tests to see how good they are at English. Studies have shown that it can be helpful for students to use their own language when they are learning English. This can help them understand more about how language works, learn more in school, and do better at speaking English. It can also help them feel good about themselves and their culture. However, it can be hard for teachers to use students' own languages in the classroom, especially if there are a lot of different languages or if the teacher only speaks English. It can also be a sensitive topic because some people think that English should be the main language in America. Despite these challenges, it is important for teachers to find ways to use students' own languages when they are teaching, because it can make a big difference in how well English Language Learners do in school.  

Nowadays, we are starting to use teaching methods that are more sensitive to different cultures and that help preserve those cultures. But in the past, some schools had rules that said you could only speak English. These kinds of rules were not helpful because they made it seem like other languages weren't important.

 

When students who speak more than one language go to school, they might only hear English spoken there. What message does this send to them? It's better to have an "additive" approach to language, which means that students can learn a new language without forgetting the ones they already know.

We hope you and your students enjoy our Reading Comprehension activity. Happy learning!

Investigating the Ice Age Beringian Standstill Hypothesis

   

The Bering Land Bridge (Beringia) Standstill Hypothesis posits that a population of ancient humans, known as "Ancient Beringians," lived in isolation on the east Beringian Arctic steppe-tundra during the last glacial maximum (LGM, 36,000 – 12,000 years ago). According to the hypothesis, this population is the sole ancestral source of all Native Americans. The hypothesis is still being studied and debated by scholars and researchers.

Researchers from Brown University, with help from the Shared Beringian Heritage Program, are trying to find proof of a new idea about when and how people first came to America. Professor Yongsong Huang and his team believe they discovered signs of human poop and fire from more than 30,000 years ago in northern Alaska, which is way earlier than when people were thought to be there. The lab's analysis of sediment from as far back as 200,000 years has not been published yet, but Dr. Huang's research over the last five years has added a lot of new information to the argument over how people got to America via Beringia, which is a land bridge between Siberia and Alaska during the Ice Age.

 Scientists can test the Beringia Standstill Hypothesis by examining a variety of biomarkers found in Pleistocene humans, fauna, flora, pollen, charcoal, and fire-related chemical markers in the sediment cores of two volcanic lakes in Bering Land Bridge National Preserve. Additionally, they can reconstruct past climates and fire history to determine if Ancient Beringians used fire to hunt, heat, or cook during the LGM.

Some researchers have argued that the Bering Land Bridge, a strip of land between Asia and Alaska that emerged in the last Ice Age, was a highway for human migration. Scientists don't know for sure when people went from Asia to America or for how long. We do know that people were in Siberia about 45,000 years ago because of archaeological findings. But the only proof of humans living in North America is from 14,500 years ago. Some people think that during the Ice Age, the Bering Land Bridge, which was a land connection between Asia and Alaska, was used by people to travel between the two places.

There are lots of theories about why it took so long for people to move from Beringia to North America. Some people think that people stayed in Beringia for at least 20,000 years before they started to move south. That's why we don't have evidence of people living in North America before 14,500 years ago. Most of the Native Americans were still living in Alaska, Beringia, and Siberia at that time.

Some researchers think that people might have lived in Eastern Beringia during the Ice Age, separated from the rest of North America by an enormous sheet of ice. Analyses of bones found in the 1980s and 1990s at the Bluefish Caves in the Yukon Territory suggest that they could be from 25,000 years ago, which goes against the common idea that people came to North America quickly. DNA tests also show that the genetic makeup of modern Native Americans comes from a population that was isolated in Beringia for a long time. Plus, studies of the climate say that Beringia was a better place for people to live than Siberia. Even though scientists, geneticists, climate experts and biochemists are discussing the different evidence about the first Beringians, there is still some uncertainty about how and when humans came to the Americas.

In the last few decades, a new theory has been suggested called the Beringian Standstill Hypothesis (BSH). The BSH suggests that the Bering Land Bridge was a place where people lived for a long time. It's possible that people lived in Beringia, which was a large area that included parts of Siberia, Alaska, and Canada, for thousands of years during the Ice Age (about 25,000 BCE) before they moved south into North America. This theory suggests that people stayed in Beringia for a while, instead of or in addition to quickly moving into North America. While they were there, they became different from the people in Eurasia in terms of their genetics and culture. 

The Beringian Standstill hypothesis suggests that the Bering Land Bridge was a place where people lived for a long time, allowing them to become genetically and culturally distinct from their Siberian ancestors. During this time, the populations in Beringia experienced genetic drift and natural selection, which are processes that can lead to genetic differences between populations. This period of isolation likely caused the Native Americans to develop a unique genetic makeup that is distinct from their Siberian ancestors.
