Demolition Hammer - Neanderthal

Progressive evolution
Spawns a hybrid breed
Through natural selection
Neanderthal conceived
Barreled chest and heavy limbed
Bony ridge atop his skull
Beetled brow, immensely strong
Bi-pedal locomotion
Ape man, short statured
Slouching dim wit brute
Homo erectus
Modern sub-species
Packing spears and heavy clubs
Stalking giant prey
Neanderthal attack
A migratory herd
Mammoth charges with malice
Tries to feast upon his death
Armed with a broken ranpike
Impale it's massive chest
Butcher with stone tools
Carcass of their prey
Savage intention
Carnivorous feast commence
(Lead Reilly)
Intruding hostile cave bear
Slay the vicious beast
Snare a wooly rhino in a
Camouflaged abyss
Massive haul of bones in tow
Retreating to his dank abode
Embossing his icy lair
With a skull and bone complex
