Yes. But it probably is very slight. What we as humans have now to work with have allowed us to do the things we have done: moon landing, etc. Some people will be able to do more and so will carry us further. Natural selection occurs over very long spans of time.
There are some minor recent changes that result from natural selection on human populations that affect many of us. For instance, humans were not naturally lactose tolerant during adulthood until the keeping of domesticated animals became a widespread occupation in Eurasia, some 10.000 years ago. The trait of lactose tolerance in adults is still spreading from those first Eurasian roots. Reversely, there are some changes in human populations that may result from the *lack* of selection. Since humans change their environments to suit them, we may be able to witness degradations in the efficiency of our metabolisms, immune systems, and senses, as detrimental mutations are able to spread throughout the population. This is unlikely to result in very serious biological problems for the species, but may affect the demographies of human populations, the annual expenditure on medical care, and so on.
Natural selection is one of the main mechanisms responsible for generating the variety of life on Earth. It acts through the process of differential reproduction of individuals with traits that are better suited to their environment. Over time, this results in the accumulation of advantageous traits in populations, leading to the diversity of species we observe today.
No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
According to the theory of natural selection, the primary factor responsible for biodiversity is the process of adaptation to varying environments over time, which is driven by genetic variation and survival pressures. While invasive species can affect biodiversity by introducing competition and altering ecosystems, the fundamental mechanism of biodiversity arises from the diverse adaptations of organisms to their specific ecological niches. Thus, natural selection plays a crucial role in shaping the vast array of life forms we see today.
Natural selection is a key mechanism for evolution by which favorable traits are passed on to future generations, leading to the diversity of life. However, other factors like genetic drift, mutation, and gene flow also play a role in shaping the origin and diversity of life on Earth. Therefore, while natural selection is an important explanation, it is not the sole factor in the evolution of life.
Evolution by natural selection is currently the only viable theory explaining the diversity of life. However, the mechanism of natural selection is not the only mechanism to affect evolution. There are phenomena such as genetic drift, biased gene conversion, intragenomic conflict, and so on, that aren't exactly the same as natural selection (although they are all intertwined and all affect one another), but do affect the direction of evolution.

Everywhere where there is life.
yes they are
They aren't. Intelligent design posits that natural selection cannot create life as we know it, and inserts a deity as the cause.
Scientists explain the great diversity of life on Earth through the process of evolution by natural selection. Over millions of years, organisms have evolved and adapted to different environments, leading to the wide variety of species we see today. Environmental factors, genetic variation, and natural selection all play a role in shaping the diversity of life on Earth.

Darwin did not address the origin of life in his work on the theory of evolution by natural selection. He focused on the process of how different species evolve over time through natural selection. The origin of life is a separate field of study called abiogenesis.
they were awesome
she is brave
Darwin used the theory of natural selection to explain evolution. Natural selection is the process by which organisms best adapted to their environment tend to survive and pass on their genetic traits to offspring. This concept helps to explain how species gradually change over time, leading to the diversity of life we see today.
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
