Four Stone Hearth #90

The 90th edition of Four Stone Hearth is currently being hosted by Cfeagans on A Hot Cup of Joe. Be sure to check it out! In it, he also share with us his concerns with the dwindling response to participate. Poor chap only got 4 submissions! In his own words:

Unfortunately, participation has waxed and waned a bit over these few years. I only received four submissions and one of these wasn’t, strictly speaking, a post on anthropology. But I’m including it anyway. I’m willing to accept the responsibility for the low turn-out, and here’s why: The Four Stone Hearth blog carnival depends on us, the writers and bloggers to keep it going. The readers will be there. Some of us that host routinely get a thousand or more blog hits a day and have hundreds of unique subscribers (not me… but I’m working on it. some).

We anthro-bloggers need to rally up if we want to keep the Four Stone Hearth going. I propose using the comments section here to brainstorm ideas. Side-bar badges? Advertising? Link-Love? Get PZ Myers to submit?…

The next Four Stone Hearth edition will be hosted by Sexy Archaeology on April 28th.

Australopithecus sediba and "missing link"

The announcement last week of a new hominin, Australopithecus sediba, garnered a lot of media attention and of course among the academic circle. The remains of an adult female and a juvenile male was found deposited inside a cave in Malapa, South Africa by Lee Berger and his 9 year-old son. These fossils are thought to date about 1.9 million years ago and are probably a descendant of Australopithecus africanus.

Brain scans reveals the possibility that a chunk of brain is still intact inside the brain case, along with some fossilized bugs. Google Earth was also credited for discovering these fossils. Lee Berger have been used Google Earth to map out known fossil deposits and caves. Armed with these knowledge, Berger found 500 previously unidentified fossil deposits and cave sites.

For more about A. sediba, read:

• Kambiz's post on Anthropology.net, Australopithecus sediba (UW88-50) of Malapa, South Africa.
• Jackaroo's post on Lawn Chair Anthropology, Holy Effing Crap II: Australopithecus from Malapa.
• John Hawk's post on John Hawks Weblog, What, if anything, is Australopithecus sediba?
• Scientific America: Discoverer of "Lucy" raises questions about Australopithecus sediba, the new human species from South Africa.
• Science/AAAS: Special Feature: Australopithecus sediba.

The discovery of A. sediba, along with the "Denisova hominin" and Homo floresiensis, sparked a lot of media coverage but unfortunately the lingo "missing link" seems to be almost always paired with such discoveries. One should be cautious when using the term "missing link" as most links among known fossil records are not really "missing". Our evolutionary past is not a long linear chain but more like branches coming out of a tree trunk. Remember the missing link, "Aunt Ida" (Darwinius masillae) who turned out to be just a fossil primate on the dead end of an evolutionary branch? Some of these branches indeed lead to evolutionary dead ends, so claiming that all new discoveries are "missing link" is false. For more on the etymology of the phrase "missing link", read John Hawks's "A missing etymological link" and Carl Zimmer's "Yet Another 'Missing Link'".

Female Rhesus macaques: Grooming, group size, and feeding priority

Michelle from Spider Monkey Tales has an interesting post about her poster: Grooming, group size, and feeding priority in female Rhesus macaques in Cayo Santiago, Puerto Rico. You can check her poster if you happen to be going to the 79th annual AAPA meeting in Albuquerque, New Mexico.

Life as an interspecies surrogate mother

I hope everyone enjoyed yesterday's April Fools post. No, I am not going on a Bigfoot expedition although I truly am interested in the Bigfoot "phenomenon", in a scientific standpoint.

Life has suddenly taken on an interesting turn for me this week. My friend found a 2 day-old kitten near his house and who's an orphan. Next thing I know, I've became the surrogate mother of this adorable kitten. She is a fighter and a very cute one to boot. In mere 24 hours, I've finally understand what it feels like to be a mother; constantly checking up on the baby, feeding the baby every few hours around the clock and even burping the baby after feeding. So, blog posts will be quite limited for about a month as I will be spending most of my time with her (much to the chagrin of my other 2 cats).

I'm going to dedicate this blog post to my beloved grandmother who passed away suddenly yesterday. She is an important person in my life. She taught me how to love, be courageous and be independent. Of course the most important thing she instilled on me was how to be mischievous. Without her, I'd be just like my kitten ... lost, cold and hopeless. I lived with my grandmother for 15 years while my parents are in the US. I had not seen my grandmother since 2002 and it turned out that it would be my last time.

I love you, grandma. Don't be a naughty girl anymore.

Bigfoot, here I come!

My advisor once told me that I should keep my passion for Bigfoot to myself because other primatologists would think I am cuckoo and no one would take my research seriously. However, I'm pretty elated right now and I figured I should share this good news with you, my readers. 

I have been selected to be part of an expedition to collect scientific evidence on the existence of Bigfoot. While some information about this expedition is to be kept hush hush until it concludes, I can tell you that this expedition was proposed after frequent sightings of a bipedal ape-like creature in the woods of this area. I will meet up and start the expedition with a few cryptozoologists sometimes around May. These self-proclaimed cryptozoologists, like me, are primatologists who had kept their passion for Bigfoot in the dark from the academia. 

Sightings of Bigfoot have long existed in the Pacific Northwest, with the now infamous 1967 Bigfoot sighting (and video) of Roger Paterson and Robert Gimlin. However, recent sightings suggests that expanding Bigfoot population is starting to make its way to the Northeast as well.

The most popular theory explaining the existence of Bigfoot is that it is a relic population of Gigantopithecus that crossed the Bering land bridge or Beringia from Asia to America, much like the saber-toothed cats. Dr. Gustav von Koenigswald was the first to discover the fossil remains of Gigantopithecus in an apothecary shop in China, which he later named Gigantopithecus blacki.

Others proposed that Bigfoot is a relic population of a species of Paranthropus instead, judging from the similarity of a crested skull and bipedal gait. However, Paranthropus sp. only occurred in Africa. Unless a small population of these hominin made its way to America, it is very unlikely that Bigfoot evolved from the Paranthropus branch. The existence of Bigfoot is undeniable from the plethora of sightings. I am hoping that this trip will possibly once and for all proved that Bigfoot really does exist. While 2009 is the year of the Flores "hobbits", 2010 will hopefully be the year of Bigfoot. 

Imagine what a relieve it would be (especially me) that Bigfoot will no longer be featured in cheesy cryptozoology programming such as MonsterQuest. C'mon, those cheesy graphics doesn't help establish the fact that Bigfoot exists. For shame! Even ABC-TV "Wife Swap" is featuring a family of Bigfoot hunters! Check out Loren Coleman's article on Cryptomundo. 

This is what Bigfoot is supposed to look like according to MonsterQuest.

I'm currently reading Joshua Blu Buhs's book, Bigfoot: The Life and Times of a Legend. Hopefully I'll finish reading the book before the expedition starts. So, who said a primatologist can't do fieldwork in North America? Hopefully the experience from this expedition will provide me with enough leverage for grad school application next year!
