protists
Organisms of the same species will share common traits.
Scientists added the kingdom "Protista" to classify organisms that exhibit both plant and animal characteristics. This kingdom includes a diverse range of eukaryotic microorganisms, such as algae (which have plant-like traits) and protozoa (which share animal-like traits). Protists play a crucial role in various ecosystems, often serving as primary producers or as part of the food web.
The method you're referring to is called "selective breeding" or "artificial selection." This process involves choosing specific organisms with desirable traits to breed, with the aim of producing offspring that exhibit those traits. It is commonly used in agriculture and animal husbandry to enhance certain characteristics in plants and animals.
Three key traits that define an animal are: they are multicellular organisms, they are heterotrophic (meaning they obtain their food by consuming other organisms), and they exhibit specialized cells and tissues that enable complex functions. Additionally, animals typically have the ability to move at some stage of their life cycle and possess a nervous system for responding to their environment. These characteristics distinguish animals from other life forms such as plants and fungi.
An "species" is the smallest classification subgroup of organisms that have the same traits and can interbreed to produce fertile offspring. Members of the same species share genetic and physical characteristics.
Ancestral traits are characteristics that are inherited from common ancestors of a group of organisms. These traits can provide valuable insights into the evolutionary history and relationships among different species. Studying ancestral traits can help scientists understand how traits have evolved over time and how organisms are related to each other.
An organism is any individual living entity that can function independently, including animals, plants, fungi, and microorganisms. An animal, on the other hand, is a specific type of organism that belongs to the kingdom Animalia, characterized by traits such as multicellularity, heterotrophy, and the ability to move at some stage of life. In summary, all animals are organisms, but not all organisms are animals.
purposely mating organisms with desired traits
yes! plants have traits.
Humans affect artificial selection by selectively breeding organisms with desirable traits, leading to changes in their genetic makeup over generations. By controlling the mating of organisms, humans can accelerate the process of evolution to develop specific characteristics in plants, animals, and other organisms. This process has been used in agriculture, animal husbandry, and even in pets to produce desired traits.
Bacteria belong in their own domain (a massive range of organisms) and do not have the traits of plants and animals who are made up of numerous cells unlike bacteria.
Linnaeus considered physical characteristics, such as anatomical structures and reproductive organs, along with behavioral traits to classify organisms. He also examined the overall morphology and life cycle of organisms to categorize them into different groups based on similarities and differences.
