i heard that creatures had to evolve the ability to reproduce
You probably hear that on a creationist forum/new/site/video?
Sorry, but that is not a reliable source. ever heard that cells duplicate? like, they divide and become two cells.
when has a random mutation ever been helpful
Some bacteria evolved defences against antibiotics/antibiotica, you don`t have to view it as helpfull for the human race, it was helpfull for the bacteria.
There! evolution debunked...
Sorry, but that was not the case.
last time i checked, sickle cell anemia was a bad thing
last time you checked...Do you ever check out things that doesn`t support your belief? NO.
you cant say that it took millions of generations to "invent" sex
We don`t.
Evolution randomly spits out mutations and the bad ones die out
You cross-over!
"nothing is random, but evolution is as close as it gets"?
I say, "Nothing is random, so is evolution" There are several causes for mutation, the environment, the other beings, maybe even damage taken from another specie? When mothers give birth after they had a drink, the baby has some chance of getting mutated. There are so many factors that i cannot list them all here.
70 percent of all mutations are bad, but still there are 30% who doesn`t and then im not including the mutations we don`t notice wich doesn`t cause any damage at all!
Now you might argue that then since 70% are bad species will have gotten extinct a long time ago, but, the mutations only occur at one of the individuals, then if it is bad, that creature will die and not reproduce, if it is good, it will have a advantage over the other members of the specie, and evolve. There are of course individuals without mutations, and they are the majority, so if a good mutation shows up, it will reproduce more quickly, with taking less damage than the other members.
A harmful mutation decreases the individuals rate of survival in the environment.
If the mutation is beneficial however, it will increase the fitness of the individual and/or promote traits that are desireable.
Here is from wikipedia:
Mutations are changes in the DNA sequence of a cell's genome and are caused by radiation, viruses, transposons and mutagenic chemicals, as well as errors that occur during meiosis or DNA replication
Beneficial mutations
Although most mutations that change protein sequences are neutral or harmful, some mutations have a positive effect on an organism. In this case, the mutation may enable the mutant organism to withstand particular environmental stresses better than wild-type organisms, or reproduce more quickly. In these cases a mutation will tend to become more common in a population through natural selection.
For example, a specific 32 base pair deletion in human CCR5 (CCR5-Δ32) confers HIV resistance to homozygotes and delays AIDS onset in heterozygotes. The CCR5 mutation is more common in those of European descent. One possible explanation of the etiology of the relatively high frequency of CCR5-Δ32 in the European population is that it conferred resistance to the bubonic plague in mid-14th century Europe. People with this mutation were more likely to survive infection; thus its frequency in the population increased. This theory could explain why this mutation is not found in southern Africa, where the bubonic plague never reached. A newer theory suggests that the selective pressure on the CCR5 Delta 32 mutation was caused by smallpox instead of the bubonic plague.
Another example, is Sickle cell disease which is a blood disorder in which the body produces an abnormal type of the oxygen-carrying substance hemoglobin in the red blood cells. One-third of all indigenous inhabitants of Sub-Saharan Africa carry the gene, because in areas where malaria is common, there is a survival value in carrying only a single sickle-cell gene (sickle cell trait). Those with only one of the two alleles of the sickle-cell disease are more resistant to malaria, since the infestation of the malaria plasmodium is halted by the sickling of the cells which it infests.
Since devolution's going on now, why can't it always have been going on
Why can`t Evolution and "Devolution" have been going on at the same time? It can have been always going on, but evolution has too.
Don`t tell me you seriously belive that "man used to be higher than a house and now theyr growing smaller and weaker and dumber"?
Yah, you have to have random chance create reproduction with a female and a male at around the same time, and the male has to be attracted to the female and every little detail has to be perfect or else reproduction couldn't happen.
A simple answer would be: NO
A scientific answer would be long and boring:
The details of the female doesn`t have to be perfect, but occasionally you will meet someone with almost the exact deatails you need, then you will fell in the phenomenon "Love", your statement is not objective, without any evidence to support it. This is what evolution call: Species.
The guy is going to have to evolve his genitals and the female must evolve hers, and they have to be compatible. Besides how's the guy going to evolve his genitals, a little sensitive lump evolving to genitals?
I understood very little of that, but i`ll try.
The genitials doesn`t have to be compatible,there is no such thing as exact compatible if thats what your pointing to. that is something called what? a specie?
Anyway, you still have to get the female and the male before any of that........... No Opinion
Simply, no, you must have the chromozomes to reproduce sexually, asexually however you will only need one individual, a cell for example.
Nice that there is more creationists, hmm... there should be a poll: Creationism or Evoltuion...
