In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates.Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring.
Bateman's principle, in evolutionary biology, is that in most species, variability in reproductive success (or reproductive variance) is greater in males than in females. It was first proposed by Angus John Bateman (1919–1996), an English geneticist. Bateman suggested that, since males are capable of producing millions of sperm cells with ...
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism.
Asexual reproduction can proceed by budding, fission, or spore formation and does not involve the union of gametes, which accordingly results in a much faster rate of reproduction compared to sexual reproduction, where 50% of offspring are males and unable to produce offspring themselves.
Sexual maturity is the capability of an organism to reproduce.In humans, it is related to both puberty and adulthood. [1] Puberty is the biological process of sexual maturation, while adulthood, the condition of being socially recognized as an independent person capable of giving consent and taking responsibility, generally implies sexual maturity (certain disorders of sexual development ...
Pumpkins just keep getting bigger and bigger each year, and scientists and farmers don't even know how large they can get. You're not imagining it. Pumpkins just keep getting bigger and bigger ...
Pumpkins, squashes, and gourds are all part of a botanical family of fruit known as the Cucurbitaceae family. It's a big family with over 900 species ; that said, they do have some differences.
By old age, [clarification needed] the sex ratio reverses, with 81 older men for every 100 older women; [For this statistic to be meaningful, it is necessary to define the age range that is meant by "old age".] across all ages, the global population is nearly balanced, with 101 males for every 100 females.
