Quote where Kant even vaguely suggested that fetuses or zygotes are "persons," "moral agents" or "rational beings":

Kantian personhood is defined by Kant himself as follows:
"Only a rational being has a will—which is the ability to act according to the thought of laws, i.e. to act on principle"
http://www.earlymoderntexts.com/assets/pdfs/kant1785.pdf (pg 18)
However if taken at face value, this definition excludes many groups of people (infants, fetus's, comatose patients, sleeping humans etc). However Kant himself later clarifies that his definition extends all of humankind (i.e those who eventually will become rational, and those who once were rational, i.e comatose patients). Later Kant confirms this with is formula of universal law, which states:
"Act only in accordance with that maxim through which you can at the same time will that it become a universal law"
Universal Law here, extends to past, present and future, and hence encapsulates current rational agents, future rational agents, and past rational agents. I mean, heck if we directly apply the principle to abortion , it contradicts itself.
(Basically according to this law, if abortion is moral, then it is a universal law and must be moral for all past, present and future agents. However if this was a universal law, and everyone acted upon it, then your parent's would have aborted you, and hence you are unable to get an abortion since you would not exist. Therefore the principle cannot be acted upon and willed into a universal law at the same time. Therefore abortion is wrong in all cases).
Though I admit, this is only an interpretation of what a Kantian person is. Philosophers are arguing about this issue too. However, when I put forth my definition to my professor, he agreed that my definition was also his interpretation of Kant's work.
The following paper not only reviews some of the recent evidence on consciousness of self in non-human animals, the authors describe the series of experiments they conducted that provide probably the most definitive demonstration to date of recognition of volitional self-agency in chimpanzees, directly contradicting Kant's baseless claim that humans are the only creatures on earth who are self-aware:
Self-awareness not the same as being able to have will (act upon moral principles). In order to have an understanding of such principles, you need a to either develop a social culture (only possible in humans) or have complex emotions like empathy (again the data shows this is only possible in humans). The research paper you have quoted does not show this at all.
Were your claims about cranial capacity supposed to relate in any way to your speciesist position that pre-viable fetuses and zygotes should be granted a "right to life" but not even the intelligent, loving, functional adult hominids of a different genus (namely, chimpanzees)?
No. My claims about cranial capacity were relating to the fact their are certain behaviors found in hominems (such as culture, language, high order emotions such as empathy) which are not found in hominids. This was evidence for my claim that their is a fundamental difference between the human species and the hominid species
which grants the human species a greater right to life. Not only that right to life extends to all eventual subjects who will attain that morally valuable stage. I shall put it simply.
P1: Rational (Kantian definiton) Human beings have a right to life.
P2: This right to life extents to all those subjects who will eventually becomes rational agents (zygotes, infants).
P3: Sentient non-rational beings such as chimps also have a right to life.
P4 This right to life also extend to all those subjects who will eventually becomes sentient non-rational beings (baby chimps, zygote chimps).
P5: The right of life that is derived from rationality is greater than the right of life that is derived from sentient non-rationality
C: Therefore a human zygote or infant has a greater right to life than even an adult chimp.
You haven't cited any evidence whatsoever that any "form of intelligence," culture or empathy "are simply not possible" for any hominid genus. (To the best of my knowledge, chimps do not have the complexity of spoken language such as humans do merely because the physiological structures of their mouth, throat or face, not because of any difference in cranial capacity.)
It isn't possible in chimps. I am sure I can find evidence, but a quick google of cultural evolutionary data will show you that the huge increase in cranial capacity from hominids to hominems allowed human beings to do certain things (like form social groups, have altruistic behavior, develop language and complex emotions). The cranial capacity (and therefore increasing size of brain) was the the primary change that led to this. Its either that, or my anthropology professors were lying to me all semester

(1) In fact, there is a good deal of controversy in both ethics and philosophy of law regarding whether children have rights. See:
http://plato.stanford.edu/entries/rights-children/#CriChiRig Moreover, in both ethics and legal documents, all assertions of rights can be restated so as to eliminate any reference to a "right". I agree that in both ethics and legal documents, the purpose of "rights talk" is to secure moral and lawful behavior, and other than that, I take no position on the metaphysics of any "right".
(2) Even if you could coherently define the classification "empathetic adult," the fact that a child may or may not some day become one does not justify granting any child any right, just like the fact that a child may or may not become a responsible spouse and parent some day in the future does not justify granting a 4-year-old the right to marry.
Interestingly, the withholding from children or non-recognition for children of various rights that adults enjoy (e.g., the right to consent to medical procedures, or to enter into contracts) is done to protect children, and adults and society in general, not to deprive children of anything.
Marriage is not a fundamental right. Fundamental Rights are moral ought not principles that are assumed we have.
It is not a question of a child may or may not become an adult. Rather, in the natural state of order, the child will become an adult and thus the government has a mandate to protect their legal rights. See, the way rights work in government, is that the citizens of a state consent to be government by the state. They give some service to the state (like they pay taxes, or work to keep society functioning etc) and in return the state has a mandate and duty to protect certain rights of those citizens (i.e right to life, autonomy, etc). However, this protection of the state does not extend to only current citizens, but also future citizens (infants, children's, teenagers, those individuals who do not yet contribute to society) and past citizens (the elderly). In this way certain rights (esp the fundamental ones, in contrast with voting etc) are given to all citizens and eventual citizens. I have a strong reason to hold that fetus are eventual citizens/moral persons.
.
I do not accept that there is any analogy between causing an unwanted child to be born and a winning lottery ticket.
Again, the argument was illustrating the strong moral difference between potential and eventuality in order to refute your claim that gametes and zygotes are equal in terms of rights
You can't argue that unless you can first deduce that an unwanted child will have “positive experiences”.
I deduce the same way you deduce that the child will have negatives. Generally, existence itself is a positive experience. When are hungry and we eat nice food, that is a positive experiences. When we form relationships with others, that is a positive experiences. When we listen to music we like, and watch movies we like, that isa positive experiences. When we are educated and we have a passion for a career, that is a positive experiences. I would happily argue that there are more positive experiences in life compared to negative ones and these could apply easily to the future of an unborn child..
