Some Somalis have become like Hoteps.
Forget oral History, historical records written by non-Horners, has Afars in the Bab El Mandeb area before Somalis, and they still occupy the African side of the Bab E-M.
Names transcribed on a historical map cannot be reasonably used to hypothesise that these are Somali clans when we do not know how they would have been pronounced in the respective native tongue.
Afars gradually lost some of their their Eastern territory to Somali Dir clans after the latter expanded beyond Zeila.
Afar's influence on Somali is as an adstrate and not a substrate which puts holes in any suggestions that they came before in areas like Zeila and were either absorbed or pushed out. There's also the fact that Dir subclans like the Guragura and the Habar Maqdi were found near Harar as early as 500 years ago according to the Futuh al-Habasha:
[The Somali tribes gather for the jihad ]
It was after this that the Mahra party and the sharif Muhammad reached the imam who feted their coming on account of the jihad ; and then he sent to all the districts of the Somalis and to the tribes of Harla. Then all the tribes rose up.
The first tribe to come up was the Habr Maqdi with their lord Garad Dawit, fifty knights and five-hundred foot-soldiers. After them the Marraihan came up, with their lord Ahmad bin Hirabu, with eighty knights and seven-hundred foot-soldiers. After them came up the Gorgorah with Garad 'Abd their chieftain, and thirty knights and one-thousand foot-soldiers.
Then the tribe of Girri came up, with their chieftain Garad Mattan along with eighty knights and one-thousand foot-soldiers. In the same way the tribe of Zarba came up from Harla with their lord the sultan Muhammad with twenty knights and three-hundred foot-soldiers. The tribes assembled - all of them volunteers and on good terms with one another. The number of the horses in readiness was around five-hundred, and there were twelve-thousand foot-soldiers, not to mention those who carried the provisions and other things besides.
And when al-Umari talks about the people of Zeila during the 1300s he mentions that they "cultivate two times annually by seasonal rains … The rainfall for the winter is called ‘
Bil’ and rainfall for the ‘summer’ is called ‘
Karam’ in the language of the people of Zayla" which are words more or less out of the
Somali calendar and not used by Afars or any other group as far as I know. And I doubt whatever Somali group lived there at the time, a few hundred years before the Futuh, were Isaaq or Darood or something. Most likely Dirs. Dirs have been far west of the northeast for at least 500 years and I would bet money probably as much as 700-800 years going off of Umari.
