INDEX Analvsis:
Aberrations are huge constructs primarily composed of Chimera-generated material but may also incorporate pre-existing structures. Purpose unknown.
Observational studies of Aberrations detail: Oozing Sprawl, twisted half-formed Archaean variants, towering spikes of carapace fused in a mass. Personnel report various visual and auditory phenomena. (INSERT: Hibana - I heard... voices, Garbled, but definitely voices.) Further investigation suggests formation occurs when expanding Chimera colonies (Sprawl) encounter some yet unknown element in an environment. (INSERT: Mira - Could it somehow be searching this out? Theories?)
EXTRAPOLATIONS:
Theorizing on formation of Aberrations: Appearance and rate of expansion imply rampant growth. Marked by a state of molecular excitation and chaotic instability. Uncontrolled. Malformed non-viable organisms support the hypothesis. Probability High.
Expanding on formation of Aberrations: Presuming Chimera bacterial memory, Aberrations may result from the meeting of Sprawl and fossilized Chimera DNA. Investigate genetic variance resulting in frenzied growth. (INSERT: IQ - So perhaps some form of recombinant reaction?)
PROTOCOLS:
Aberrations are high-priority observation sites due to the frequency of unexplained phenomena.
