Question

В отличии от факторов эволюции растений и животных в развитии человека большую роль играли: а)борьба за существования б)естественный отбор в)развития мышления и речи г)искуственный отбор

Answer 1

Развитие мышления и речи

Answer 2

The question is about the factors that played a major role in the development of humans, as opposed to the evolution of plants and animals. The answer is:

- в) развития мышления и речи (the development of thinking and speech). This factor is unique to humans and has enabled them to create complex cultures, technologies, and civilizations. The development of thinking and speech is closely related to the evolution of the human brain, which is larger and more complex than any other animal's brain. - г) искуственный отбор (artificial selection). This factor is also specific to humans and refers to the intentional breeding of plants and animals for desirable traits. Humans have domesticated many species of plants and animals, and have modified their genomes through genetic engineering. Artificial selection has influenced the evolution of both humans and their domesticated organisms.

- а) борьба за существования (the struggle for existence) and б) естественный отбор (natural selection) are factors that affect the evolution of all living organisms, not just humans. These factors are based on the principle that organisms with traits that are better adapted to their environment will survive and reproduce more than those with less favorable traits. Natural selection is the result of the differential survival and reproduction of organisms due to the struggle for existence.
