[4] [5] Thus, a knowledge of mutation bias can be used to design more evolution-resistant therapies. [4] When mutation bias is invoked as a possible cause of some pattern in evolution, this is generally an application of the theory of arrival biases, and the alternative hypotheses may include selection, biased gene conversion, and demographic ...
Due to natural selection, the percentage of Neanderthal DNA in ancient Europeans gradually decreased over time. From 45,000 BP to 7,000 BP, the percentage dropped from around 3–6% to 2%. [13] The removal of Neanderthal-derived alleles occurred more frequently around genes than other parts of the genome. [13]
This was followed by an explosion of Canis evolution across Eurasia in the Early Pleistocene around 1.8 million YBP in what is commonly referred to as the wolf event. It is associated with the formation of the mammoth steppe and continental glaciation. Canis spread to Europe in the forms of C. arnensis, C. etruscus, and C. falconeri. [23]
Homo erectus reconstruction, Natural History Museum, London. In an article published in 2021 titled "Interpopulational variation in human brain size: Implications for hominin cognitive phylogeny," it was found that the brain size of Asian H. erectus over the last 600,000 years overlaps significantly with modern human populations.
They are known to have one of the most relaxed and leisurely birthing seasons. They breed cautiously in the treetops during the monsoon season. Their habitats are breeding grounds for danger, as they can easily fall prey to their natural predator, the amethystine python, which also climbs and lives in the treetops. Tree-kangaroos are known to ...
The idea became taboo following the United Nations' 1994 International Conference on Population and Development, where framing human population growth as negatively impacting the natural environment became regarded as "anti-human". [170] Most human populations throughout history validate this theory, as does the overall current global population.

It is an evolution of the original Vega launcher, designed to offer greater launch performance and flexibility. Approved for development by the European Space Agency (ESA) in December 2014, Vega C was designed to accommodate larger institutional payloads and compete effectively in the commercial launch market.
