Korzenie klasowe

Zamiast ziemniaków jedliśmy topinambury, a camembert był jak wapno - opowiadają starzy Francuzi i brzmi w tym echo heroizmu i wyrzeczeń, jakich wymagały czasy okupacji. Camembert po wojnie odzyskał kremowość i utrzymał popularność, ale topinambury na bardzo długo stały się symbolem niedostatku i jarzyną tą pogardzały kolejne pokolenia. O zmiennej hierarchii produktów i potraw w felietonie Ludwika Lewina

Wybory mis(s) Azji

Rzecz jasna, mis z gorącą, smakowitą zawartością. Będą to potrawy akurat na listopadowy wieczór, pełne intensywnych, korzennych aromatów, mięsne i wyraziste. Od razu robi się lepiej, bardziej energetycznie i kolorowo. Plus odrobina egzotyki, bez konieczności wychodzenia z domu

Owoc zmysłowy bardzo

Potrafi doprowadzić do ekstazy najbardziej zimnokrwiste jednostki. Ocieka miodem, nurza się w płatkach migdałowych, w cytrynowym cieście objawia całą zapiekłość. Gruszka to ma temperament! No i jeszcze ten kształt...

Ojczyzna dziczyzna

Wnętrza zamku w Gołuchowie pod Kaliszem zachęcają do powrotu w dawne czasy. Kiedyś jesień była okresem polowań i uczt, podczas których na stole królowała dziczyzna. W jadalni bywało gwarnie i dostatnio. Chciałoby się zostać tu dłużej, niestety, o 16.00 solidne drzwi muzeum zamykają się. Można jednak klimat zamku przywołać w domu: znaleźć stary kandelabr, zapalić świece i zaprosić przyjaciół na sarninę z kurkami, a potem podać herbatę i fefernuski upieczone według dawnej receptury

James Bond w jadłospisie

James Bond, jak wiadomo, nie tylko był równie sprawny w biciu i zabijaniu, jak odporny, kiedy jego usiłowano bić albo zabić; nie tylko rozmiłowany w kartach, golfie oraz innych formach hazardu; nie tylko miewał godne pozazdroszczenia romanse z urzekającymi jego i nas kobietami; ale przywiązywał też sporą wagę do jedzenia i picia

Wielki plebiscyt „Kuchni” i konkurs

Szanowni Czytelnicy! Oto dwie kolejne propozycje drugiej edycji plebiscytu, w którym wybiorą Państwo Kucharza - odkrycie roku. Przez sześć miesięcy będziemy prezentować dania i sylwetki dwóch kucharzy. Nasi czytelnicy mogą na nich głosować, wygrywając przy okazji atrakcyjne nagrody. A za pięć miesięcy kapituła złożona z kulinarnych ekspertów wyłoni zwycięzcę spośród trzech kucharzy ocenionych najwyżej

Paweł Pojawa - z restauracji Likus Concept Store w Warszawie

Surf & turf

Znaczy to tyle, co danie mięsno-rybne. Łączenie mięsa z owocami morza należy do tradycji krajów śródziemnomorskich. My mamy takie połączenie w wersji pięcioskładnikowej

Sielskie jadło

Na lnianym obrusie, w ceramicznych miseczkach. Popijane kwaśnym mlekiem lub wybitnym winem. Wakacyjne jedzenie. Niekoniecznie przaśne, byle w plenerze. W pełnym słońcu i pod błękitnym niebem (Przepisy dla 4-6 osób)

all creationist ... ( 4 weeks ago by N3CR1S)

all creationist need to read this, and understand it. i promis, the statement i am going to give you is really simple, so you should be able to understand it. here it comes: since Iriducible complexity says that a process or thing CAN NOT have evolve, it is sufficient to, without any prof at all except logic, design a way for which it COULD have happened to dissprove the Iriducible complexity statement.

many of you have ... ( 4 weeks ago by N3CR1S)

many of you have certainly heard the idea that atheist cannot dissprove god, since it is impossible to do soo. you would have to test all possible things and look everywhere, simply put, it is IMPOSSIBLE to prove that something is unexisting. this is often used by creationist. have they not seen that the same aplies to "iriducible complexity"? they cannot prove that the evolutional way that this process happend does not exist. they cannot both keep the cockie and eat it at the same time.

I hate your videos, I always have to read them and my eyes are getting old from all this youtubeing and plus you always play that damn annoying classical music, but your logic makes up for it in the end I suppose =P

Un-scientific ... ( 3 weeks ago by Prohoridzo)

Un-scientific statements: "Everything else is fluff, evolved to improve the rate and specificity of sexual reproduction as organisms evolved more complex multi-cellular forms." and "At first all combinations are possible,M+M,F+M,F+F but because out-breeding increases genetic variation,eventually M-F will evolve to be the only combination that works." That's all conjecture not fact. What possible environments would Nat.Selecion favor out breeding vs. in-breeding? Outbreed < Inbreed mutation.

Vagus nerve. Nice. Anyone who has had a vasovagal reaction knows what a pain the the ass the vagus nerve us. Sent me to the hospital once. Suggestions for further reading on the subject?

"What possible ... ( 3 weeks ago by Eskarina6)

"What possible environments...?" Umm. ALL? (Known long before genes were discovered.) In-breeding causes problems, but not through mutation. It has no more genetic mutation (copy errors) than out-breeding; there's just far less genetic variation from which to work to counterbalance extant would-be genetic problems in an organism. In-breeding tends to force the problems to arise because there are fewer options--less variation--available than in out-breeding. (Think dominant & recessive traits.)

You asked about the ... ( 3 weeks ago by lynchmobb2000)

You asked about the vagus nerve. I actually remember the vagus from one biology lecture in college. Gail Patt, a Bio Prof at Boston University gave this as slam dunk evidence of evolution which it is.
Don't know if she has further writings on the topic. Cheers.

"Unscientific"? No. In the first case, he just showed that everything else normally associated with sexual reproduction is only to enhance the efficiency of the existing form of reproduction, which is two haploid cells fusing and undergoing meiosis. Everything else IS fluff. Eskarina6 answered the other point, so I'll just leave it at that.

i dont know were to being, first of all it says, WARNING contains SCIENCE, yet throughout ALL the video all i got was predictions and theorys about how sex evolved (also the eye evolution vids etc) why couldnt the Eye have just been Born if evolution is true? why cudnt it just have grown one flowery day on a jellyfish or somthing? aaahhhh see you dont know that, if evolutoin is true you would have NO IDEA how sex evolved, so why make this VIDEO, are you INSANE? Glory to GOD most high

LOL, well to each their own. :)

If evolution is ... ( 1 week ago by LordZentei)

If evolution is true, an eye could not have just grown on a jellyfish one "flowery" day, because evolution does not work that way. On the contrary, a complex organ like the eye does not spontaneously appear, it has to develop over many generations through a series of mutations/adaptions that progressively add new functions from simple beginnings.

but u miss the point of my comment, my comment was ment to Emply even is evolution is true, you do not know how the eye Formed and evolved, why does the eye have evolve the way scientist's say? why cudnt it have evolved another way? Thus my point, you dont know that it didnt evolve another way,in fact, you dont know how it evolved at all, but from the evidence i see from the world around me, The eye is created Identical to that of its mother, no Beneficial mutations, so y shud i believe in them?

Okay: the first ... ( 1 week ago by LordZentei)

Okay: the first point is that there ARE beneficial mutations, there are plenty of such instances documented. Second: the fact that the eye CAN evolve in the way shown eliminates the need to postulate an intelligent designer. Third: we have fossils. Fourth: please learn to spell, it makes your posts less painful to read.

Love the videos, don't read me wrong here.
In the graph showing penis and vagina size distribution, I think ther is a problem with confusing centimeters and inches. In the penis length, you show the VAST majority of men with penis length under 10 cm, that is only 4 inches. I believe the average is more like 6-6.5 inches. Just wanted to

"From a scientific ... ( 5 days ago by soylentgreenb)

"From a scientific standpoint, what is the advantage to sexual reproduction vs. asexual reproduction?" Asexual reproduction produces nearly exact clones with a mutation here or there; these organisms all share similar vulnerabilities. Asexual reproduction is faster. Sexual reproduction produces a vast variety of new and unique combinations of already existing genetic material, especially in outbreeding.
