Top 10 Species Humans Have Forced To Evolve To Survive

2. What is the biggest change in skull anatomy that occurred from the dawn horse to the modern horse? The size of the skull is dramatically larger in the modern horse.

I believe we’re rapidly heading towards a human-scale transformation, the next evolutionary step into what I call a “Meta-Intelligence,” a future in which we are all highly connected — brain to brain via the cloud — sharing thoughts, knowledge and actions.

If climate change is caused by humans, then no organisms can avoid selection resulting from human actions. Climate change impacts every corner of the globe. And species evolve in turn. Humans created the selective force (antibiotics) and applied them to microorganisms.

As with any other species, human populations are shaped by the usual forces of natural selection, like famine, disease or climate. Although it does shield people from other forces, culture itself seems to be a powerful force of natural selection. People adapt genetically to sustained cultural changes, like new diets.

Reproduction not only allows the human race to continue surviving, it also provides the opportunity for further physical and spiritual evolution of the species into more advanced states. This is the same reason reproduction exists for all species, animals and plants.

Overwhelming evidence shows us that all species are related–that is, that they are all descended from a common ancestor. More than 150 years ago, Darwin saw evidence of these relationships in striking anatomical similarities between diverse species, both living and extinct.

Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

Natural selection occurs if four conditions are met: reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual.

Survival of the fittest, term made famous in the fifth edition (published in 1869) of On the Origin of Species by British naturalist Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing.

In biology and genealogy, the most recent common ancestor (MRCA), last common ancestor (LCA), or concestor of a set of organisms is the most recent individual from which all the organisms of the set are descended. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms.

But if the DNA damage occurs to a gene that makes a DNA repair protein, a cell has less ability to repair itself. So errors will build up in other genes over time and allow a cancer to form. Scientists have found damaged DNA repair genes in some cancers, including bowel cancer.
