Furthermore, the posture and joint structure issues would not make it any easier. Flight is not about feathers or membranes only. It incorporates a whole change of lifestyle and morphology. | |
| Oct 4, 2016 at 2:52 | comment | added | user93 | the question flying animals without feathers but distantly related to them existed quora.com/Did-pterosaurs-have-feathers inspiration could be drawn from them. en.wikipedia.org/wiki/Pterosaur#Pycnofibers | |

| Oct 3, 2016 at 6:34 | comment | added | Mike Scott | @YoustayIgo Monkeys arose about 60 million years ago. That's easily long enough for changes in arm length in a gliding and then flying species to evolve -- it's not a difficult evolutionary change. In about the same amount of time, something that was originally like a deer evolved into a blue whale. | |
| Oct 3, 2016 at 6:28 | comment | added | Youstay Igo | @MikeScott: you are comparing bird mass to mammalian mass. Also, you have not explained how you are going to provide the long arms (and fingers) required for membrane attachment and how long that evolutionary change would take place. Furthermore, you would also need to explain how the transitioning monkeys would live in dense trees, considering their newly acquired membranes are very thin and sensitive and prone to tearing easily. | |
| Oct 3, 2016 at 6:21 | comment | added | Mike Scott | @YoustayIgo Swallows migrate thousands of miles. They are small birds with small wings -- they weigh about 20g. I'm afraid that all of your theories can be easily disproved by reference to the real world. | |
| Oct 3, 2016 at 6:18 | comment | added | Youstay Igo | @MikeScott: two things to keep in mind. OP said They should have branched of from the same ancestors as present day monkeys No modern monkey has arm length to body length ratio of any bat. OP also specified that they should be able to fly large distance. Small, 100g monkeys would not be able to fly large distances. Long distance flight requires manipulation of thermal currents which requires a large wing area, which requires a large wing ... which you cannot get with a 100g marmoset. | |
| Oct 2, 2016 at 6:14 | comment | added | Mike Scott | @YoustayIgo The pygmy marmoset weighs 100g. The Mauritian tomb bat weighs up to 1.6kg, 16 times as much. There's no need to do any scaling, as there's already a very wide overlap between the sizes of bats and monkeys. | |
| Oct 2, 2016 at 3:46 | comment | added | Youstay Igo | @MikeScott: Now try scaling up a bat to the size of a monkey and report how that goes for your little adventure. | |
| Oct 1, 2016 at 8:17 | comment | added | user93 | Since I have specified as migratory gliders are ruled out | |
| Oct 1, 2016 at 7:22 | comment | added | Mike Scott | If powered flight is "almost impossible to evolve in mammals", how do you explain 1,200 species of bat? About 20% of all mammal species have powered flight. | |
