How can adaptations for manipulation within a lineage exist?

Postby AlexB1001 » Fri Oct 29, 2010 12:54 pm

Nature is not harmonious. Males manipulate females to mate with them, and some possess traits that allow them to force their sperm into the female, or rake out the sperm already inside the female. The same stands for the opposite - females can decide which male's sperm they actually use, digesting or discarding sperm from a male they decide will provide substandard offspring. Now I can see how adaptations against the opposite gender propagate, as despite the fact they spend roughly 50% of the time in the opposite sex, they can be switched on for males and switched off for females and vice versa. That I understand.

It still works for male/male competition within a species, where the male who has a better sexual adaptation is more likely to mate and propagate his adaptations, and with parents and children, where children who learn best to manipulate the parents are most likely to grow into parents, while parents who are best at manipulating their children are most likely to have more children.

This is where I completely fall apart - eusocial insects. How can members of, say, an ant nest have conflicting adaptations against each other - how can this work, propagate, and lead to a stable community? I am truly confused.

I'm not sure what conflicts exist in an ant colony, except for those among active mating members, and those you understand. Could you give an example?

No adaptations.
Technology for life in Antarctica can be created in California.

If women choose world champions in swimming for partners, will man become a fish?

Sorry enarees, but what on earth do you mean? Of course there are adaptations within a lineage, I was asking how they could develop!

Examples:
Some male insects (Damselflies) have 'penis scoops' to remove all the sperm from a previously inseminated female.
Some types of Drosophila inject the female with an anti-aphrodisiac to prevent her from mating after he fertilises her.

These are genes in a male that, while being silenced if the genome of the offspring of the male is female, will be passed on to the genome of his male youth. Therefore within a lineage, males and females can have adaptations against each other!

And if women choose world champions in swimming for partners, men won't become fish, but their offspring will certainly tend to be better swimmers!

I wonder what you're actually trying to say here...

These species are genetically created for those qualities. They have found their niche with their occurred properties.

...
After three generations they will get tired of swimming, as communism.
There is a powerful biological tool for separation and detection of performances.

I'm sorry, but I just don't think we see eye-to-eye here.

Imagine that in workshop "Edem" biological organisms are made and they are let out for testing around the world. People even like in their workshops good conditions to be .

NOTE: In general actively discussing with enarees is not very productive. Going on his website (tinfoil hat mandatory) accessible by clicking his name might inform you why. But I cannot recommend that as serious damages to sanity are a strong possibility after reading that....

I wish I could help with your problem, but I have no answer to offer.
