A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources.

Then he saw it: the telltale gleam of a fossil tooth partially exposed on the rocky ground. “I knew immediately that it was a hominid tooth,” says the University of Tokyo scientist, “and one of the oldest ever found.” It was more than that. Suwa had uncovered nothing less than a new chapter in the history of human evolution. He and his colleagues report in the current , Nature that the archaic molar, along with other fossils they found in the area on expeditions in 1992 and 1993, belong to a previously unknown species. This diminutive, humanlike creature walked the earth some 4.4 million years ago — half a million years earlier than the oldest human ancestors ever identified. That stretches our family tree back almost to the era when humans and apes branched off from a single ancestor. In fact, says University of Liverpool paleontologist Bernard Wood, whose commentary on the find also appears in Nature: “It looks to me like this is either the common ancestor or damned close to it. I think we’re splitting hairs not to call it the ‘missing link.’ “ Paleoanthropologists have not unearthed anything this revolutionary since 1974, when the famous fossil skeleton known as Lucy was discovered about 50 miles north of the current find. That 3.2 million-year-old female hominid had some human characteristics — most notably, she walked on two legs rather than four — but skull and tooth fragments indicated she was somewhat apelike as well. She fit nicely into the shared-ancestor theory first put forward by Charles Darwin and supported by modern comparisons between human and ape proteins and DNA. The divergence between the ape and human lines, argued the biochemists, came somewhere between 4 million and 6 million years ago. And some paleontologists predicted that as hominid species were discovered from periods closer and closer to the time of the actual split, they should be even more apelike than Lucy. That’s exactly the case with the new species, which now bears the scientific name Australopithecus ramidus (ramid means root in the local Afar language). Like Lucy and her clan, known as Australopithecus afarensis, ramidus had teeth with some apelike and some human characteristics. But at least one specimen — a baby molar still attached to a piece of an immature ramidus jaw — resembles a chimpanzee tooth more than a molar from any known hominid. “It’s obvious that it belongs to an ancestor of afarensis,” says Tim White of the University of California, Berkeley, a co-author of the Nature report and a leader of the international team that uncovered the new fossils. The researchers found very few bones from below the neck, and those they found were in fragments; chew marks on the bones show that the hominids’ carcasses were ravaged by carnivores. That makes it hard for anyone to be sure what these creatures looked like and how they walked. The fossils suggest that at least some members of the ramidus clan were about 4 ft. tall, but that doesn’t establish what the range in height was. In some African apes, males are considerably bigger than females, as they were in Lucy’s species as well. Says White: “We do know the arm bones come from an individual that was larger than Lucy, but we don’t know if it was male or female.” Most experts assume ramidus walked on two legs, as Lucy did, but the evidence is skimpy and indirect. One clue is a tiny fragment of the foramen magnum, the opening at the base of the skull where the spinal cord joins the brain: its location suggests an upright stance. Moreover, the structure of the arm bones is different from what anatomists see in knuckle-walking apes. If ramidus really did travel on two legs, anthropologists may have to rethink their notions of what started pre-hominids on the evolutionary road that led to modern Homo sapiens. It is already clear from Lucy, who stood upright but had an apelike skull, that bipedalism came first and a large brain later. But what prompted the shift to two-leggedness? The conventional theory is that a change in climate transformed the eastern and southern African forests to dry, open grasslands, favoring apes that could walk upright; they would have been able to see predators from farther away and walk long distances holding food or children. It appears ramidus may have lived not on the savannah, however, but in some sort of forest. Mixed in with the hominid fossils, the scientists found thousands of fossilized tree seeds and abundant petrified wood. There were also some 600 specimens from other animals, including such forest dwellers as monkeys, kudu antelopes, bats and squirrels. Notably rare were fossils from grassland beasts like prehistoric horses or giraffes. The theory that ramidus was a forest dweller is still not proved, but if it is supported by more fieldwork and analysis, then theorists will have to form a new explanation for the development of erect posture by some apes. While the evolutionary story is still in some doubt, there is no question about the fossils’ antiquity. Ancient bones cannot be dated directly, but geochronologists proceed by determining the age of nearby rocks. It also helps if the fossils have lain undisturbed since they were buried. In this case, the ramidus bones could not have been better placed: they were enclosed in sedimentary rock that was neatly sandwiched between layers of volcanic ash, which contains radioactive isotopes that make material easy to date. The volcanic layer just beneath the fossils turned out to be about 4.4 million years old. That jibes perfectly with the ages of other fossil animals found, which were already known from analysis of other sites. Scientists are debating whether the new hominid is really the common ancestor of both humans and apes, whether it’s the first species to appear on the human side after the split or whether there are still several pre-ramidus hominids left to be found. Liverpool’s Wood thinks White, Suwa and company may have discovered the seminal species. The man who found Lucy in 1974, paleontologist Don Johanson of the Institute of Human Origins, based in Berkeley, California, disagrees. “I still think we’re a long way from the common ancestor,” he argues. “We’re one link closer, just as Lucy was a link closer. There could be room for several more species.” All these issues — bipedalism, the forest-dwelling theory, the question of how high ramidus sits in the evolutionary tree — can be settled only with more fieldwork. The team is returning to Ethiopia next month, to the site, hoping to find parts of other skeletons and uncover more clues about the Ethiopian environment of 4.4 million years ago. Says White: “We’re going to crawl on our hands and knees, looking for every giraffe, pig, bird, rodent, seed and any other fossil we can find.” Humanity has just added half a million years to its heritage; perhaps the next expedition will give scientists a better idea of how much further back our line of ancestors goes. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6726083/one-less-missing-link/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6726083/one-less-missing-link/"},"headline":"One Less Missing Link","datePublished":"1994-10-03T04:00:00.000Z","dateModified":"2026-02-28T08:37:54.777Z","description":"Bones from the Ethiopian desert prove that human ancestors walked the earth 4.4 million years ago","url":"https://time.com/archive/6726083/one-less-missing-link/","keywords":[],"thumbnailUrl":"","author":[{"@type":"Person","name":"Michael Lemonick","url":"https://time.com/author/michael-d-lemonick/"}],"articleSection":"U.S.","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/section/us/","name":"U.S."}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/archive/6726083/one-less-missing-link/","name":"One Less Missing Link"}}]}] ```
