At the time, and even now, a probability of this magnitude did not come without controversy. 333 collection. The title basically tells it all, “Sexual dimorphism in Australopithecus afarensis was similar to that of modern humans.” The authors made about 30 different measurements of bones from A.L. The name was originally created just for this species found in South Africa but several closely related species now share the same genus name. We acknowledge Elders past, present and emerging. Unfortunately, because 9 complete skeletons weren’t found, the fossils used in the analysis are not all one anatomical element… rather, some are humeri, some are radii, others are femora, etc. sediba’ fossils to be a chronospecies of A. africanus – meaning that the slight anatomical differences between the new fossils and A. africanus are due to changes over time within a species rather than them being from different species. I won’t get into that just yet, but I will overview some of the key points raised in the last 25 years with a specific emphasis on recent back and forth brouhah from two different camps. The A.L 333 study offered up a quick and terse response that same year. Join us, volunteer and be a part of our journey of discovery!

To all you who live and breath statistics, this maybe a big bad faux pas — but really what else are you to do, make no analysis at all? Australopithecus, means ‘southern ape’. This species lived about 3.6 million years ago and is the first from the genus Australopithecus to be discovered outside of southern and eastern Africa. afarensis individuals left a 24.4-metre- (80-foot-) long trail of their own footprints frozen in time. All known specimens have been found at various locations in South Africa. For many people interested in human evolution, this is an interesting question because sexual dimorphism can explain early mating systems. This would extend the time range for A. africanus by almost half a million years.

I could assume that since you shared this link on early Homo dimorphism, then australopithecines were dimorphic too. Tim from remotecentral just sent me this link. Fossils from two individuals were recovered in 2008 and announced as a new species Australopithecus sediba in 2010. I’ve been told by many different professionals that if the data and the methods seems too complex, if they bring derivatives and calculus into to the fold, then something is fishy. It got a lot of people talking about robust australopithecines being representatives of the male sex, whereas the more gracile ones are females.
