The most recent survey I could find was from 1985 which said that 16% of biologist disagreed that "[t]here are biological races in the species Homo sapiens."
I was wondering if there's been a change in this position.
Unfortunately, it’s not easy to determine a scientific consensus since nobody has cited a relevant survey. On the other hand, here are some salient quotes from scientific literature (stolen from the answers to the above-mentioned question) which I find worth repeating:
Which speaks against the existence of races as a meaningful biological concept.
On the other hand, Jorde & Wooding (2004) contend that,
But they concede that
Finally, it’s worth noting that in the universally agreed-on taxonomy, formalised in the International Code of Zoological Nomenclature there simply is no category for races, whether they would make sense or not. Whether or not this view enjoys a majority vote in biology, it’s the de facto consensus.
Anatomically modern humans are less than 200K years old, left Africa (or possibly Africa and Arabia) only 60K years ago, and migrate quite a lot (think of the Mongol invasion). So you would not expect to have clear divisions into subspecies. And indeed a quick search of google scholar pulls up no claims in the literature for human subspecies of anatomically modern humans (i.e. no subspecies of homo sapiens since Neanderthals and Denisovans).
On the other hand, it's certainly the case that you can work out a rough phylogenetic tree of humans. Native americans are descended from certain northern and eastern asians, and so in the 1400s were more closely related to them then they were to other humans. Similarly, Austronesians (of Indonesia and Polynesia, e.g.) are more closely related to Taiwanese aborigines than they are to Australian aborigines. This tree is complicated by how much more migration there has been in the last 1000 years than there was previous to that, but it's still biologically meaningful.
But here's the striking thing: traditional notions of "race" do not match up well with this tree. The deepest and most fundamental phylogenetic splits in the human tree are within Africans. If you were going to try to "scientifically" come up with races, you'd end up with something vaguely like one for Khoisan, one for other Africans, and one for all non-Africans. Even ignoring modern admixture, traditional races are not monophyletic. Any clade including all "black" people includes all people, any clade including all "east asians" includes all native americans. (Also note that traditional notions of "race" are not stable over time, remember that "Irish" used to be a "race" on the US census.)
Modern admixture even more clearly shows the non-genetic nature of traditional "races." One genetic study of people who identify as African-American, found that African ancestry can be as low as 1% and as high as 99%, with the median African-American having 18.5% European ancestry (with 30% having European y-dna). Furthermore, relatively ancient admixture (for example, in the Northern Africa, Northeastern Africa, Middle East region or in Madagascar) also complicates the situation significantly.
To summarize, although human genetic diversity is a real biological phenomenon which can be used to figure out the geographical history of people's ancestors, traditional notions of race do not match up well with the biologically meaningful concepts.
Its not known what the consensus is but there is definitely a decline in the race concept.
"The concept of biological race has declined significantly in frequency of use in physical anthropology in the United States during the 20th century. We present three kinds of evidence of this rejection of what was a core concept: (1) The frequency of articles using the race concept in the AJPA declined from 60 percent in 1918 to 4 percent in 2001 (r = -.89, p = .01). (2) Content analysis of university level textbooks of introductory physical anthropology for 1980-99 found only one textbook which supported the race concept. (3) A series of mailed questionnaires to members of the American Anthropological Association found that while 37 percent of responding physical anthropologists rejected the race concept in 1978, this rose to 69 percent in 1999.”
