decreased ability to survive changing conditions
DNA evidence shows that the Cro-Magnon were not descended from Neanderthals.
The process by which modern organisms have descended from ancient organisms is called evolution.
In biology, evolution is change in the genetic material of a population of organisms from one generation to the next. Though the changes produced in any one generation are small, differences accumulate with each generation and can, over time, cause substantial changes in the organisms. This process can culminate in the emergence of new species. Indeed, the similarities between organisms suggest that all known species are descended from a common ancestor (or ancestral gene pool) through this process of gradual divergence.Source: WikipediaContributor: Andy G (ndg619@gmail.com)
Yes and no.Mutation rates are different in different organisms, and are also dependent on how long a generation is and whether the organism reproduces asexually or sexually.There's no exact rate, but at least in humans, thanks to genetic markers, we can estimate that humans all descended from the San, in Africa about 150,000 years ago.
You are descended from ancestors.
It describes via what mechanism modern life forms derived from their common ancestors.

yes, theses ancestors are called common decent
an English naturalist who realised that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection.
Apes and humans descended from the same common ancestor.
Tamayo was born in Oaxaca. He descended from Zapotec ancestors.
Charles Darwin
First you need to demonstrate that American Natives are descended from Japanese. While American Natives probably came originally from Asia, there is no suggestion that they came specifically from Japan.
Charles Darwin's theory of evolution suggest that, yes, we are indeed descended from common ancestors of the apes. Later archaeological and DNA findings support his theory of evolution. However Christians or other religious people believe otherwise.
It is believed Filipinos descended from Malaysians.
According to the theory of evolution, originally proposed by Charles Darwin in his book "The Origin Of Species" human beings and monkeys are both descended from earlier primate species. Monkeys, according to this theory, would be more accurately described as our cousins, than as our ancestors. So actually, nobody has said that people come from monkeys. That would be a misrepresentation of evolutionary theory.
