Probably as an adaptive form of natural selction reflecting the roles of each sex. |

Specifically, females have to carry around a kid for a while, and males often compete with others to establish breeding rights. These changes probably arise on chromosomes that determine the sex and so a change to the Y chromosome would not have an effect on the female population.
It helps save time if you don't have to flirt half the day before getting to the point where you can determine their sex. |

Your condescending attitude is irritating.
I do not think this is third grade stuff and please do not expect everyone to meet your strict expectations of what "smart" posts look like. |

Females are generally 10-20 feet longer and heavier than males. |

hespera sez....Ok man, sorry, that was uncalled for. So dont respond in kind.
This is very basic stuff, but i will try respectfully to answer any questions.
is there something about dimorphism that you think doesnt fit the ToE? Why are you asking about this?
Larger females btw, make sense in terms of the birth size of the offspring. Or number of eggs laid, say. It all depends on the environmental situation. |

Hyenas are larger than males and have around the same birth size as lions but lionesses are smaller than the males.
King cobra males are bigger but female anacondas are bigger.
This theory does not apply like you say it does.
I am just curious on why the size of sex fluctuates so much in the animal kingdom...although not in the primate group. |  | | | Thread Tools | | | | Display Modes | Linear Mode | | | |
