Our initial scans of the small humanoid aliens recovered so far have revealed something quite remarkable. We're detecting components of non-biological matter embedded within their internal structure. Could these be implants of some kind?
We've made a number of interesting discoveries based on the autopsy results of the alien specimen you brought back. The research team is now referring to this particular variation as a "Sectoid," based on the unusual structure of its internal organs, which we believe to be the product of genetic manipulation. As we've seen in the field, this species also seems to harbor some sort of telepathic ability...
We've found no discernible genetic variance between any of the small humanoid aliens that have been examined thus far. They are perfect genetic copies, each and every one of them. The subject's brain is quite sizable with respect to its body, and appears to have been augmented even further with cybernetic implants of some kind. Considering the... fragile nature of this creatures physical form, it is safe to assume that these implants were intended to somehow improve the combat effectiveness of the species. Dr. Shen and the engineering team have already developed several theories as to how we might be able to adapt these implants for our own use. Additional tactical information may be available in the field when viewing hostile targets in the Unit Analysis View.
Dr. Vahlen's Personal Note: Cloning, genetic manipulation, biomedical implants... the implications of this technology and the alien's motives are not reassuring.
