For each branch split I determined the number of descendants and lists the branches that have exceptional number of descending lines. On these pages i report the branch splits that are older than 1500ybp.
A list of exceptional population jumps is reported. For exceptional population jumps i used a criterium of at least 8 descending lines for the period between 1500-4000ybp. For the period before that, i used a lower numbers, since we also have fewer branch splits, so a lower criterium can have the same significance.
A complete list of branch splits is reported separately.
Different groups have different population growth. The following reasons for population jumps are suggested:
| period | min. # of descending branches |
| 20000-8000ybp | 5 |
| 8000-7000ybp | 6 |
| 7000-6000ybp | 6 |
| 6000-5000ybp | 6 |
| 5000-4000ybp | 8 |
| 4000-3500ybp | 8 |
| 3500-3000ybp | 8 |
| 3000-2500ybp | 8 |
| 2500-2000ybp | 8 |
| 2000-1500ybp | 8 |
| Blue | Crossing Berint Strait Q, 12000 ybp |
| Blue | Centum of IE (R1b-M269 and I1) |
| Cyan | Satem of IE (R1a) |
| Green | Anatolian farmers G, 10000 ybp |
| Green | Copper Age in Middle East (J2, J1, E-M84) |
| Green | Albania (R1b-Z2103--Z2705) |
| Green | Arab Expansion (J1-FGC11) |
| Pink | Slavic (I2-Y3120 and friends) |
| Red | Chinese farmers (O) |
| Red | African agriculture and Bantu expansion (E1b-V38) |
| Red | Greece in IE language branch (J2b-L283 and E1b-V13) |
| Red | Finnic (N) |
| Red | Berber in Maghreb (E-M81) |
| Black | Others: see below |
The exceptional population jumps are in the List, with references to the origin of the population expansion.
