There was never any khoisans in somalia sxb
There are at least three extant Somali Paleo groups: the Aweer/Boni, the Eyle and the reer Manyo. Some of the af Helledi speakers may constitute a fourth group, and there may be others. The Boni-Aweer are related to the Hadza and Sandawe, who are unquestionably Khoisan.

"Evidence suggests that the Aweer/Boni, along with the related Dahalo and Wata, are remnants of the early
Bushman hunter-gatherer inhabitants of Eastern Africa. According to linguistic, anthropological and other data, these groups later came under the influence and adopted the
Afro-Asiatic languages of the
Eastern and
Southern Cushitic peoples who moved into the area.
Dahalo has consequently retained some of the characteristic
click sounds of the
Khoisan languages.

They have been driven south, but there are still some in Somalia:

"Besides the Boni and Sengwer, all current East African hunter-gatherers share common haplotypes (mtDNA L4, L3a, L0d3 and Y chromosome B2a and B2b), suggesting that the current East African hunter-gatherers might represent remnants of the previous pre-Holocene and early Holocene population in the region. The Boni and the Sengwer appear to have had substantial levels of gene flow from other neighboring populations that appear to have the hunter-gatherer “genetic signature”. In fact, the Orma and Kalenjin populations that neighbor the Boni and the Sengwer, respectively, carry hunter-gatherer haplotypes at moderate frequencies indicating possible “reverse” gene flow."

"B-M112[edit]B-M112 (M112, M192, 50f2(P)) has been found mainly among
pygmy populations in Central Africa,
Juu (Northern Khoisan) populations in Southern Africa, and the
Hadzabe in East Africa. It also has been found occasionally in samples of groups who neighbor the aforementioned populations.
Specifically, haplogroup B2b has been observed in 67% (12/18) of a sample of Baka from Central African Republic,

Tanzania,
