Would a hominin evolutionary tree look thin and spindly or full and bushy?

A) The hominin evolutionary tree would look full and bushy because it would have started about 6 mya with multiple branched branches throughout the millennia.
B) The hominin evolutionary tree would look thin and spindly because it started about 6 mya and followed a straight linear progression from Sahalenthropus tchadensis to Homo sapiens.
C) The hominin evolutionary tree would look full and bushy because is started only 2 mya and has many branches between Homo habilis to Homo sapiens.
