(b) Number of gains (red) and losses (blue) per million years ...
Here is a good link to the figure
Suppl. Fig 7
If we figure an average generation time of 25 years, that would give us 40,000 generations in a million years. So to calculate the number of generations to gain or lose a gene we can divided number of generations by number of mutations per million years.
organism
| # genes gained
| # genes lost
| mutation rate / gen
| # gen. / loss or gain
|
Human | 250 | - | .0063 | 160
|
" | - | 50 | .0013 | 800
|
Chimp | 50 | - | .0013 | 800
|
" | - | 150 | .0038 | 260
|
Orangutan | 30 | - | .0008 | 1300
|
" | - | 200 | .005 | 200
|
So... worst case, humans gained, on average, 1 gene every 160 generations, that is every 4,000 years. Orangutans lost a gene every 5,000 years.
What's the incredibly high mutation rate you see here?

ABE: Here is the original paper that figure is from in case anyone is interested.
Common Marmoset genome. It is quite an intense paper, with around 100 authors, a dozen supplemental figures and about 40 supplemental tables.
Edited by herebedragons, : added link to original paper
Edited by herebedragons, : the colors indicating loss or gain in Suppl Fig 7 were swapped around, the chart above has been corrected to reflect this.

Whoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for... I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca
"Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.
Ignorance is a most formidable opponent rivaled only by arrogance; but when the two join forces, one is all but invincible.
