Has a new cousin of Adam been discovered?

Anyone who has visited East Africa has heard the name of the pair of paleontologists - Lewis and Mary Leakey who became famous after they discovered fossils of the first human-like monkeys and later fossils of the first creatures that were associated with the genus Homo (man).

Later, based on the findings, they established the identity of the upright man (Homo erectus), who has since been considered the species from which the thinking human species (Homo spines) evolved. The Leakey couple's son is Richard Leakey, a friend of a paleontologist named Maeve. About forty years ago, the pair of paleontologists Richard and Maeve Leakey discovered a fossil of a creature that lived in northern Kenya about 2 million years ago. The fossil received the code 1470 and was named by a colleague - Homo rudolphensis.

The remains were discovered near Lake Turkana (Northern Kenya). The couple claimed that the creature belonged to the human species and that it existed at the same time as the one who is considered the father of the (new) human race, Homo erectus - the upright man. The 1470 existed at the same time, and despite an external resemblance, it is another species that has been extinct for many years. Based on 1470, the Leakey couple claimed that at the same time as the "upright" existed, there existed two other and perhaps more human species, which later became extinct.

Many paleontologists objected to the assumption of "a number of human species in Africa in the period 2 million years ago" and the debate continues even today.

More fossils were recently found that were identified as belonging to 1470, which led the couple to publish the find (and their opinion) in the journal Nature.
Maeve describes the production as "having a flat face and jawbones that are not prominent".

The remains were discovered at a distance of about 6 km from the site where 1470 was discovered (Lake Turkana), in the last forty years the "disputers" claimed that 1470 was "upright" sick or a mutant, the finding of the "new" fossils by the Leakey couple is a reinforcement of the assumption which is a new cousin.

However, it turns out that in the same environment, fossil remains of "hominids" were discovered that do not belong to Zacoff nor to 1470, which means, according to the couple, these fossils belong to a third species.
That is, three species of man that existed side by side, two that became extinct, while the upright one developed into the new man. is that so?

Contrary to convention, the two species (1470 and the second) did not receive official names as the debate continues. The opponents claim (again) that 1470 is Homo erectus (the upright), and the other remains belong to the skillful human species (Homo habilis).

Paleontologists claim that "the pair of leeks jump too far based on little evidence", and it is possible that the differences in the jaws due to which the leeks determined that these are new species could be differences between a male and a female or between a young and an adult.

Others accept the new species definition and support the assumption of three species that lived at the same time. The knowledge that one or more species lived in a certain period is important for understanding the development of the human species, since in an environment where there are several species of the same type - the competition between the species increases, while when there is only one species - the development is from one species to the next.
And as mentioned, the debate continues.
