A human is completed at conception. Yet they have the right of a parasite until reaching 24 weeks of existance?

A clump of cells? we are all made up from clumps of cells! Do I get to inject lethal injection into pro abortionists clumps of cells, IE them- no I don't! DRs may give us stupid names like embryo & foetus leading up to our birth, but we all know they are talking about humans.

DRs are not impartial in the matter, as they wish to experiment on/mutilate & extract an embryos genetic matter. IVF produces excess embryos which are often destroyed as clinical waste. Plus the cost of delivering/raising each child is seen as a burden. To judge whether someones life is worth living is mere opinion.

I'm not particularly religious. But I would pray for scientists to create humans incapable of obtaining pleasure from intercourse & to unleash them on society. To breed & hopefully eliminate the sickness of the infliction. Rape & accidental pregnancy would become a thing of the past.

How did the first two sexually reproducing organisms obtain all of the abilities needed at the same time? Males and females would have had to evolve simultaneously while still reproducing to continue the survival of the species.

Just think about it okay... You have a species reproducing asexually, how likely is it that while reproducing asexually the same species turned into a male and a female while still constantly reproducing at the same time and how is it that simple organisms could come up with the idea to create reproductive organs in male and female and knowing they will work to reproduce?

Would someone like to explain?

Otter's have a tail that helps with swimming, but a California sea lion's tail is a small nub that couldn't help with swimming or supporting the sea lion. Why is it still there?

I never understood how birds evolved to be able to fly. Sure flying is a great evolutionary tool, but to fly you need hollow bones, wings, and small awkward legs. Individually these traits are harmful, so how could the random mutations of hollow bones or wings be succesfull along the way until the birds could fly. Random mutations are very slight and it takes a long time to evolve even a minor change.

I have ever read the article that actually human being has pheromone that will attract mosquito to bite. That's why there is product called mosquito repellant that will cover the pheromone from human body so that mosquito can not "smell" it. But I would like to know whether there is any relation between "blood type" with the "human pheromone"? So that the human being with "B" blood type will attract mosquito more than others? Is it because the pheromone in human with "B" blood type stronger than other blood types? Please help. Thanking you in advance for your kindness.

what is spontaneuous generation? who were the key players in determining that spontaneuous generation does not happen? what did they do? Explain how scientists believed life began on earth. What organisms were first to develop. Who were Miller and Urey? What did they do? What role did oxygen play in the evolution of life?

If everything evolved from a simple single celled organism that reproduced asexually (dividing) how would evolution ever favor something that had much worse odds of ever happening like sexual reproduction? How would that ability have evolved? How could it even have started --- what are the chances that 2 (not just 1) of these single celled organisms simultaneously mutated and developed the ability to reproduce sexually? And even if they did -- why would the trait be favored? -- it seems that within the first few generations the offspring would have found some difficulty in finding one another or successfully mating -- and eventually die out. How could it have happened by chance?

when a person dies (defined by no brain wave and no heart activity) do many of the cells live on? If so, do they mutate, or merge or form another... something? This is terribly complicated... I'd love to hear other thoughts on this... Thank you...
