Question:Does all animals must perform sexual activities in-order to reproduce? Did human learn about the technique of reproduction from animals? These questions came to my mind when i was watching a creationist video.They shows evidence of god's existence -Day and Night,Good & Bad,Male & Female,Positive & Negative etc

Answers:different animals reproduce in different ways. Humans are a type of primate, primates are a type of mammal and mammals reproduce sexually. But not all animals are like that. Consider the earthworm. Look up how it works for them.

Question:i need to do i report on the anilmail that does, would it be like human because bacteria in ur body uses asexual reproduction and humans use sexual reproductioon? i have no idea. so do u have an animal?

Answers:Organisms that reproduce through asexual reproduction tend to grow in number exponentially. However, because they rely on mutation for variations in their DNA, all members of the species have similar vulnerabilities. Organisms that reproduce sexually yield a smaller number of offspring, but the large amount of variation in their genes makes them less susceptible to disease. Many organisms can reproduce sexually as well as asexually. Aphids, slime molds, sea anemones, some species of starfish (by fragmentation), and many plants are examples. When environmental factors are favorable, asexual reproduction is employed to exploit suitable conditions for survival such as an abundant food supply, adequate shelter, favorable climate, disease, optimum pH or a proper mix of other lifestyle requirements. Populations of these organisms increase exponentially via asexual reproductive strategies to take full advantage of the rich supply resources. When food sources have been depleted, the climate becomes hostile, or individual survival is jeopardized by some other adverse change in living conditions, these organisms switch to sexual forms of reproduction. Sexual reproduction ensures a mixing of the gene pool of the species. The variations found in offspring of sexual reproduction allow some individuals to be better suited for survival and provide a mechanism for selective adaptation to occur. In addition, sexual reproduction usually results in the formation of a life stage that is able to endure the conditions that threaten the offspring of an asexual parent. Thus, seeds, spores, eggs, pupae, cysts or other "over-wintering" stages of sexual reproduction ensure the survival during unfavorable times and the organism can "wait out" adverse situations until a swing back to suitability occurs.

Question:i ask this question because i have a project in science about people and animals.

Answers:get a blood test done for std (sexual transmitted diseases )before performing sex without condoms ONLY way to be certain because there are diseases like Clamidia that cannot be noticed until you try to have babies and makes you infertile genetal herpies can be unnoticed as well and stay with you forever

Question:The human reproductive system is incredibly complex...slight problems/variations in the female body can easily result in the death of the egg/fetus AND the woman. Now, add the male to the equation...Evolution requires that males and females co-evolved in perfect harmony...each change in males was matched by a corresponding change in females...or extinction occurs. So how can the exact same evolutionary mechanisms (internal and/or external) that cause males to become "more male," simultaneously cause females to become "more female?" (in perfect harmony, mind you) The only possible (non impossible) explanation is that humans evolved as individuals having BOTH male and female organs...and then once reaching full development...slowly "devolved"...a split...one group becoming only female; the other only male (again, in perfect harmony). But this is required of ALL animal species. There is no plausible answer. This is one of the reasons I find Evolution to be absurd.

Answers:What is absurd is the idea that a species has to evolve first, and *then* split into two sexes! Evolution provides a far more sensible answer ... the human species evolved from a long legacy of ancestral species that already had two sexes. Earlier primates, earlier mammals, earlier therapsids, earlier reptiles ... all species with two sexes ... but different levels of sexual dimorphism (secondary differences in size and characteristics) ... until we come to an ancestor that, yes, had both male and female organs. There is nothing "absurd" about that answer unless you already have decided that Evolution (common ancestry) is absurd, and *then* concluded that evolution of human reproduction is impossible. In other words, you are failing to see the how you have put the cart before the horse in your thinking. First you have decided that Evolution is "absurd" (apparently thinking that the world's biologists are morons because they have overwhelmingly accepted an "absurd" theory as the backbone of modern biology for 150 years). And *then* you characterize the details of evolution in truly absurd ways in order to justify your conclusion. So please, why don't you actually *ask* these questions to people who do not believe evolution to be absurd *before* reaching your conclusion. If hundreds of thousands of the world's brightest scientists for over 150 years ... people who live, eat, and breathe biology ... have accepted evolution as the central unifying theory of modern biology ... then even if you believe they are wrong ... they are not *absurdly* wrong. To believe they are is to call the entire scientific community nothing but a bunch of idiots. And calling the scientific community idiots doesn't give your argument much scientific credibility.
