Oogamy: Inventing the Sexes
نویسنده
چکیده
The male-female dichotomy has evolved independently in nearly all lineages of multicellular organisms. Why this should be the case is still uncertain, but recent studies of mating-type genes in green algae open a promising new way to explore molecular-genetic aspects of the evolution of dichotomous sexes.

Ecological models explaining the success of distinctive sperm and eggs (oogamy).
Several lineages have independently evolved from isogamy (all sexes producing similar gametes) through anisogamy (dissimilar gametes) to the familiar male (producing sperm) and female (producing eggs) condition of most large, multicellular organisms (oogamy). A variety of hypotheses explaining the selective mechanisms causing such evolution and the success of these lineages have been proposed, ...
متن کاملSelection for Mitochondrial Quality Drives Evolution of the Germline
The origin of the germline-soma distinction is a fundamental unsolved question. Plants and basal metazoans do not have a germline but generate gametes from pluripotent stem cells in somatic tissues (somatic gametogenesis). In contrast, most bilaterians sequester a dedicated germline early in development. We develop an evolutionary model which shows that selection for mitochondrial quality drive...
متن کاملThe evolution of sexes: A specific test of the disruptive selection theory
The disruptive selection theory of the evolution of anisogamy posits that the evolution of a larger body or greater organismal complexity selects for a larger zygote, which in turn selects for larger gametes. This may provide the opportunity for one mating type to produce more numerous, small gametes, forcing the other mating type to produce fewer, large gametes. Predictions common to this and ...
متن کاملبررسی نقش زنادقه در جعل حدیث
One of the major concerns of the scholars of hadith is the important question of fabricating and inventing hadith. Of the reasons and motives behind fabricating hadith different views have been expressed. “Freethinking” as one of the destructive and influential movements in Islam has been the centre of attraction for the students of hadith. Nevertheless, the terms free thinking and free think...
متن کاملInventing Prepares Learning Motivationally, but a Worked-out Solution Enhances Learning Outcomes
Solving an open problem as proposed by inventing and productive failure approaches has been shown to prepare learners effectively for subsequent direct instruction even though invented solutions are often suboptimal for the given problems. Inventing can make the learners aware of knowledge gaps (cognitive) and more curious about and interested in the learning contents (motivational effects). Ho...
