we also have the most polluted gene pool by about 30-60% of ANY animal population. Where's your pedestal now? I'd say that there are far more dangerous things than predators out there for the human race...war being an obvious example. One you might not be aware of is our little plasmodium friend called "malaria". You honestly can't tell me millions of deaths per year to malaria doesn't count as predation. Another terrifying and impending thing is an airborne plague. Wasn't the black death responsible for 1/3 of Europes population dying at one point? I'd take a few bears and lions over that ANY day if we are talking about individual mortalities.
you can't call that predation as malaria affects all species, and humans do have medicine and vaccines for many diseases that still kill many more animal species than humans. rabies is one example. natural disasters and war do not count as predation. look at human populations, they don't decrease or stay the same year to year. every year they increase. look at many animals species, many of them are decreasing rapidly. humans do not have any predators. you cannot argue with this fact. your argument about war and disease is weak. they may kill many humans, but the population continues to increase.
There are actually two different measures. For those that care for their young and have a conservative amount of young, success is measured by those offspring that go on to have offspring of their own. Therefore successfulness reproductively means you basically have to be a grandparent. For something that spawns en mass, such as insects, it's simply a measure of how many infants survive in the wild as they don't put any effort into infant care.
thats not true from a biological standpoint. the sucess of a one generation is the ability to create another generation. regardless of the care a parent gives to its offspring, if it has unfavorable traits, chances are it will die in the wild. look at coloration as an example. many species change color to blend in with their environments as a mechanism for survival, to avoid predators. if an animals coloration makes them stick out, predators will be able to prey on them. over time, this will decrease the number of individuals with a certain coloration and begin to favor a different trait.
Incorrect. Luck cannot be denied. Do you have any idea how many turtle hatchlings bite it to birds on the way to the water just by dump luck? Do you know how many actually DROWN in the waters along the beach on their way into deeper water because they are so tiny? A bad wave hitting or a bird dumbly selecting you is all it takes for your 'fitness' to go out the window. Of these lucky ones, fitness is a big issues though. It's not a matter of a single generation passing genes, as you seem to fixate on. It's the accumulation of many, many reproductive events eventually leading to a more solid set of traits for their environment.
that is very weak argument. dumb luck means nothing in evolution. just because a few individuals have luck does not mean they will significantly affect the gene pool. eventually a trait will arise that protects turtles from the effects of "big waves." im not focusing on one generations traits, evolution takes place over the course of many years. you seem to contradict yourself. "of these lucky ones, fitness is a big issue." like i said, luck means nothing. eventually these unfavorable traits will be cease to be passed on to the next generations.
Actually humans had a rapid evolution leading up to modern man. If you think the 1 million years it took to get from some 'cave man' and cycle through several different species is anything but very rapid, you are incorrect. People are not in stasis, as many people think. Think about it this way: We have undergone a HUGE environmental shift, making it easier on us. We also have intellectual pressures as well as artificial stress that is off the charts. Surviving offspring doesn't necessarily mean the genes will be passed- do you think someone with severe downs syndrome or autism has much chance of reproduction? Sorry if it offends anyone, but they aren't exactly reproductively competative.
i did not mean the evolution from cave man to homo sapien. i was discussing the present day evolution of man. it will takes generations upon generations for even the smallest evolutionary to take shape because we dont have random mating, etc. also, just because you the individuals that have downs' syndrome arent mating actively doesnt mean that the disease will not show up. downs' syndrome is caused by crossing over in meiosis. a couple who do not have downs' syndrome can produce a baby with downs' syndrome.
also, luck can be denied. science is about hypotheses and being able to get the same results over and over, not just being lucky a couple times.
