Hmm... I have very little knowledge so please correct me ifOriginally posted by einsteinian77
but a peerfectly evoled being wouldn't need to reproduce, correct?
Firstly, there is no such thing as a 'perfectly evolved being'. The closest thing that exists to that, is a being which happens to fit into a particular niche exceptionally well. But, over time, the environment changes, the predators around it change, its prey changes...stuff changes, and so too, must the well suited organism.but a peerfectly evoled being wouldn't need to reproduce, correct?
Umm...well, i guess so. But I wouldn't say that this is the reason why. It is true...but I think death and birth etc have an origin which comes from quite different reasons to this.Originally posted by drag
If one organism exists for a long time it's cells would
mutate and it would get all messed up, so that's why we
don't just live on but rather nature "installed" a mechanism
which makes us get older and eventually die. The new generation
has it's source in a single piece of code - so it's perfect
and with no different mutated cells at the very beginning.
Umm..in the begining, this wasn't necessarily true. At some stage, the food was just CO2 and other chemical elements not yet within the 'life cycle'...such as CH4, NH3 and whatever... and originally, there were no predators. Predators had to evolve...An even simpler and more basic reason is the fact that all
life forms we know of, except humans, were and are part
of some food chain. So a creature that can't reproduce will
be extinct rather quickly - which makes no evolutionary sense.
A mutation is a random change in the genetic material (DNA) of an organism. It can occur during the replication of DNA or due to external factors such as exposure to radiation or chemicals. In evolution, mutations can lead to changes in an organism's traits, which can be beneficial, harmful, or neutral.
No, mutation is not the only cause of evolution. Other factors such as natural selection, genetic drift, and gene flow also play important roles in the process of evolution. However, mutations are the original source of genetic variation, which is necessary for evolution to occur.
Yes, mutations can be beneficial for an organism. Beneficial mutations can lead to new traits that give an organism an advantage in its environment, increasing its chances of survival and reproduction. These mutations can then be passed on to future generations, driving the process of evolution.
External factors such as exposure to radiation, chemicals, and certain viruses can increase the rate of mutations. Additionally, errors during DNA replication can also lead to mutations. However, the rate of mutations is also influenced by the organism's DNA repair mechanisms, which can correct or reduce the occurrence of mutations.
Yes, mutations can be harmful for an organism. Harmful mutations can lead to changes in an organism's traits that are disadvantageous in its environment, decreasing its chances of survival and reproduction. In some cases, harmful mutations can even cause genetic disorders or diseases.
