In animals, structures such as antlers in deer and horns in cattle serve a similar purpose to implants by providing support for physical traits that enhance survival and reproduction. These structures are often used in mating displays or in combat for dominance. Additionally, beaks in birds and shells in mollusks function as protective adaptations that also aid in feeding. All these structures contribute to the animals' fitness in their respective environments.
If two different animals possess homologous structures, it means they share a common evolutionary ancestor. These structures may serve different functions in each species, but they have a similar underlying structure due to their shared ancestry.
pulpwood is mainly used for building houses other similar structures
It is either homologous structures or homozygous structures. Embryological structures are when different species of animals look similar in the earliest stage of development and Analogous structures are when animals look different but their function is basically the same. So just look up homologous structures and homozygous structures in your Bio book!!
Similar in appearance and function (different Orgin)
Homologous
Homologous structures among animals are similar body parts that suggest a common ancestry. These structures provide evidence for evolution because they indicate that different species share a common evolutionary history and have evolved from a common ancestor.
They live in different environments. They have similar basic functions.
Structures that are similar are called analogous structures. These structures may serve similar functions but have evolved independently in different species.
Similar structures that evolved independently are called analogous structures, or analogies.
Animals that are most similar to humans share characteristics such as complex social structures, advanced cognitive abilities, tool use, communication through language or gestures, and the ability to experience emotions.
Structures which are fully developed in one group of organism but reduced or possibly nonfunctional in a similar group are referred to as vestigial structures. These structures are remnants of organs or features that served a purpose in the organism's ancestors but are no longer needed in the descendant species.
Analogous structures are body parts or organs in different species that have a similar function but not necessarily a common evolutionary origin. For example, the wings of birds and bats are analogous structures because they both serve the purpose of flight, even though they evolved independently.
