| Abstract |
The living hominoids are human, the two species of chimpanzees, gorilla, orangutan, and nine species of gibbons. The cercopithecoids (Old World monkeys) are the sister group of the hominoids. A consensus about the phylogeny of the hominoids has been reached for the branching order of the gibbons (earliest) and the orangutan (next earliest), but the branching order among gorilla, chimpanzees, and human remains in contention. In 1984 we presented DNA-DNA hybridization data, based on 183 DNA hybrids, that we interpreted as evidence that the branching order, from oldest to most recent, was gibbons, orangutan, gorilla, chimpanzees, and human. In the present paper we report on an expanded data set totaling 514 DNA hybrids, which supports the branching order given above. The ranges for the datings of divergence nodes are Old World monkeys, 25-34 million years (Myr) ago; gibbons, 16.4-23 Myr ago; orangutan, 12.2-17 Myr ago; gorilla, 7.7-11 Myr ago; chimpanzees-human, 5.5-7.7 Myr ago. The possible effects of differences in age at first breeding are discussed, and some speculations about average genomic rates of evolution are presented. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 September 2022.
All research outputs
#8,135,949
of 24,397,600 outputs
Outputs from Journal of Molecular Evolution
#477
of 1,475 outputs
Outputs of similar age
#3,800
of 13,210 outputs
Outputs of similar age from Journal of Molecular Evolution
#4
of 7 outputs
Altmetric has tracked 24,397,600 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,475 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one is in the 29th percentile – i.e., 29% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 13,210 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
