Then over the course of millions and billions of years, these minute changes change again to either help or hinder the organism , those that don't adapt die out, and those that do pass on the new changes and survive.

Wonton Soup Jul 18 2015, 02:08 AM That's is what i don't get. How does mutation work in making animals live in their enviroment? As far i know dna copies itself perfectly almost everytime, the time it doesn't that is where mutation occars. I understand that bit, but i don't how that can produce creatures to grow larger and larger or grow teeths and weapons to hunt them down. DNA doesn't copy itself perfectly every time, and not every branch of original DNA is a mutation. For instance your DNA is only a percentage match to your parents. Not 100%, which would imply perfect. On that, my parents have blue and brown eyes, with type O and AB blood. I have green eyes with type B- blood. This is not a perfect copy, nor is it a mutation but a latent pattern in my lineage. Quote: How does mutation work in making animals live in their enviroment? Quote: Facts about Hammerhead Shark The shape of their head allows them to be able to find prey easier. Since their eyes are set apart they can see what is going on in various directions better than other species of sharks. They also have plenty of sensory organs in their head so they can feel vibrations and movements of their prey when they don’t see them.

When all of it was combined, we became sentient.

Firefox Favourite Manga Dragon Ball, Fullmetal Alchemist, Assassination Classroom, Deadman Wonderland	Evolution is simply successful (but random) genetic mutation over numerous generations. Genetic mutation itself is random, and more often than not, evolution produces more dead ends than it does successes. However, contrary to what some people believe, an organism doesn't simply decide one day that it wants to grow fingers. This process of growing fingers happens suddenly via random mutation. To give an example, a single individual from a species can have a mutation that makes them more resistant to UV radiation. That organism lives into adulthood to reproduce, and its offspring inherits these traits. The sun suddenly increases it's UV output, and most of the individuals in the species begin to die off, but the genetic descendants of the one who had that random mutation thrive because they're able to in their new environment. They reproduce with each other, and suddenly another genetic mutation happens that makes them have thinner fur. The climate all the sudden turns bad and becomes cold, then the species dies off. Numerous mutations over millions of generations turns a fish into a monkey, but there's no one single time when something became a different species. An offspring will and always has been the same species as its parent. It's just that the mutations were minor and over millions of generations. It's random, and the species who exist now are just lucky to have had their genetic mutations work for the environment that they live in. And the Big Bang theory and Evolution have nothing to do with each other. I don't understand where people get this assumption from. Edited by Ketchup Revenge, Jul 18 2015, 04:34 PM.

Christianity Favourite Manga The Bible	to quote one of my posts from another thread: Quote: some of it is random. there are four mechanisms regarding genetic evolution. mutatations, which are random random genetic drift, which is when the frequency of alleles in populations change over time due to random sampling error gene flow - interbreeding between different groups produces offspring that represent genes of both original populations natural selection - adaptive gene patterns in a certain environment becomes more prominent over time. so that part isn't really random edit: it's been a while so Idk any of this s* in great detail anymore, so obvs google up dat a* info.

Quote: Let's say better resistance to the cold is beneficial for the species to survive. A human has two children; one has a genetic variation that has allowed their body to better adapt to the cold than the other - ever so slightly. They both successfully reproduce, as do their children etcetera. Every now and then the genes push this a little further because it's working. That is, it's making it to the next person. 500 years later an incredibly cold winter occurs. That's the thing I don't get how it starts. I understand the process once it gets started, it just how does the person from the start gets resistant to cold?

I understand the process once it gets started, it just how does the person from the start gets resistant to cold? It's a genetic mutation. A unique piece of DNA that the mutant can pass on to his/her children. most of the times however it's the environment that changes. There is already a large number of a certain species present in an area, suddenly a cold period starts, up until then cold resistance was irrelevent to survival, but now the cold period starts they become crucial. The majority of a species dies and the one with cold resistance survive and reproduce. So it's either a genetic mutation that happens to fir the environment (though this is unlikely), or tons of genetic mutations have taken place over the years in a population of animals and when the environment changes natural selection occures and only certain genes make it through the change, thus changing the entire species of that animal itself Edited by Ginyu, Jul 19 2015, 06:59 AM.

If a species suffers, they die... Negative changes result in death, that's the basic idea behind evolution.

A bear that has evolved to only eat bamboo and sucks at reproduction.

A bear that has evolved to only eat bamboo and sucks at reproduction. Exactly, Panda's are too lazy to reproduce so they all die, it's us humans that have kept them alive. Same reason there's billions of humans on the earth. We invented medicine. We kind of broke the natural selection cycle and created a human selection cycle. But evolution is still very much present in human selection. Look at the fruit and animals we eat. Chickens have gotten fatter and fatter over the years, look up a natural banana on the internet and look as if it looks as tasty as the ones you find in a supermarket.

Well that does happen, when that happens the specimen dies, possibly the species going extinct, if there's an animal being kept alive almost entirely by humans, then evolution "failed" that creature. Like the panda just mentioned
