Homo naledi, recently discovered in south africa, has a sagittal keel, large browridge, thick cranial bones, and reduced tooth size. the brain size is small, close to 500cc. where might this new species fit in the larger pattern of human evolution in africa? a. h. naledi sits comfortably at the juncture of australopithecus and early homo, since all of its traits seem intermediate between the two. b. h. naledi demonstrates the exact mix of traits expected for a new homo fossil of this time period and this region. c. h. naledi has several traits that do not fit with the genus homo, including its large browridge and thick cranial bones; however, it must be homo because it is securely dated to 1 mya. d. h. naledi seems most likely a member of the genus homo; however, its small brain size is regarded as a primitive hominin trait more reminiscent of the australopithecines.

The correct answer is option d. "h. naledi seems most likely a member of the genus homo; however, its small brain size is regarded as a primitive hominin trait more reminiscent of the australopithecines".

Explanation:

The human evolution in Africa has been unveiled by the description of different ancestors of the modern humans, from the primitive Australopithecus afarensis to the Homo erectus. In this case, the new discovered species Homo naledi has characteristics that fit somewhere after the most primitive Australopithecus afarensis. Homo naledi has a small brain size that reminiscent of the australopithecines, however it has more modern features such as reduced tooth size and sagittal keel, which fits with the genre Homo.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
