Humans have already evolved, as the fossil record shows. Our present species is known as Homo sapiens, and our immediate ancestor species was Homo erectus. There are now many fossil remains that amply demonstrate this evolution. Also co-existing with us in Europe were Neanderthals, also evolved from Homo erectus, and Homo floresiensis (hobbit) in Asia. If we have already evolved, through adaptation, away from an earlier species to become an entirely new species, then this is possible if environmental conditions create the impetus for this, although it would take hundreds of thousands, even millions, of years.
What is sometimes known as micro-evolution is also demonstrable in humans. We know that the great apes have light-coloured skin under their hair, but black skin where exposed to the sun - as the black skin protects against the harsh sun of tropical Africa. When the ancestors of our species in Africa became more or less hairless, they adapted by developing black skin. Then the early Homo sapiens African dwellers were protected from sun damage. However, black skin is inefficient in using sunlight to create vitamin D, so when Homo sapiens entered Europe, the local members of the species adapted to the weaker sunlight by developing fair skin. This is an example of what can be termed micro-evolution.
Populations evolve, individuals are selected.
individuals do not evolve
individuals do not evolve
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.
individuals do not evolve
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
I did not evolve from anything! Individuals are naturally selected and populations evolve. Understanding this simple fact can explain certain things that creationists do not seem to understand. Such questions as, " where did the first man find the first woman? " When you understand that populations evolve and individuals are selected then you will see that questions as the one you asked and questions as the one I used as an example are just silly.
Individuals evolve through natural selection, leading to changes in the characteristics of populations over time. These changes can eventually lead to the evolution of new species within a specific genus, which may contribute to the diversification of higher taxonomic groups such as phyla and kingdoms.
Individuals evolve over time in response to their environment and experiences through a process called adaptation. This involves changes in behavior, physical traits, and mental abilities that help individuals better survive and thrive in their surroundings.
Yes, populations evolve. Individuals/genes are selected.
That are reproductively successful. The individual dies; populations evolve. Individuals are naturally selected.
Evolution is defined as a change in allele frequencies over time. Since individuals have only the set of alleles that they're born with, an individual cannot evolve. This leaves the population as the smallest unit that can evolve.
