These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.
Answer = Natural Selection
Yes, prokaryotic cells evolved before eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both. It is believed that eukaryotic cells evolved from prokaryotic cells through a process called endosymbiosis.
Charles Darwin, English naturalist, is widely known for his development of the "Theory of Evolution". He stated that every living organism evolved from a common ancestor through a process called Natural Selection.
By god!
An apomict is any apomitic plant or organism - that is, any plant or organism which goes through reproduction without going through the process of fertilization.
According to Darwin's theory of evolution by natural selection, human beings evolved through a process of genetic mutation and adaptation over millions of years. Through this process, early hominids gradually evolved and developed traits that resulted in the modern human species.
A clone is an identical organism that is produced through asexual reproduction. This process results in offspring with identical genetic material to the parent organism.
The process is known as cloning. It involves creating an exact genetic replica of an organism by replicating its DNA.
every organism comes from parents through the process of
The process which produces an exact copy of the parent organism is asexual.
We used a microscope to observe the organism.
Scientists data can only date back to when these simple, unicelluar organisms lived and thus believe other living organisms evolved through them.
Adaption.
