Vestigial!

I wouldn't say that an organism is 'primitive', it's much better to state that the organism is philogenetically old (or older in comparison to other organism). Such statement means that a species has been on earth for a longer period of time than others.

Lamarck proposed the theory of inheritance of acquired characteristics, where an organism can pass on traits acquired during its lifetime to its offspring. He believed that organisms could change in response to their environment, and these changes would be inherited by future generations. However, this idea has been largely discredited by modern evolutionary theory, which is based on natural selection and genetic mutations.
It is misguided to try to find our eukaryotic ancestor among modern-day protists because the Protists living today have been through a process of evolution just as extensive as the one that produced every other living organism.
Homologous structures are features that originated in a shared ancestor, such as the bones in the limbs of vertebrates. These features may have different functions in modern organisms but have similar underlying structures due to their common ancestry.
Vestigial structures. Sometimes put to other uses that they were not adapted for.
The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.

The antonym of "ancestral" is "modern" or "contemporary." Ancestral refers to something that is passed down through generations, while modern or contemporary refers to something that is current or of the present time.
what term defined as the study of the distributon of organisms on earth
Gregor Mendel proposed that inherited characteristics are determined by discrete units called "factors" (now known as genes) that are passed down from parents to offspring. These genes come in pairs, with one copy inherited from each parent, and they influence the traits and characteristics that an organism develops. Mendel's work laid the foundation for the modern understanding of how traits are inherited.
Darwin's idea of "descent with modification" suggests that species evolve over time through the process of natural selection, where favorable traits are inherited by subsequent generations. Fossil evidence and the study of modern organisms indicate that genetic changes accumulate over time, leading to the diversity of life we see today. This concept underpins the theory of evolution, highlighting the connection between ancestral species and their modern descendants.
Animals of the genus Ambulocetus are intermediaries between basal mammals and modern whales, and possibly ancestral to modern whales.
The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
